reading, waterproof photometer for determining key water quality parameters for swimming pools, hydrotherapy pools, hot tubs and spas. Designed for both portable and static use, the Pooltest 9 Bluetooth should always be used with genuine Palintest reagents for optimal performance. The fundamental operating technique applied to the Pooltest 9 Bluetooth is based on the principles of optical absorbance and scattering of visible light. Optical absorbance techniques are based on the use of Palintest (spectro)photometric reagents, creating visible colours with specific analytes upon reaction.The intensity of colour produced is measured with the Pooltest 9 Bluetooth and the data compared to the stored calibration data to deliver the final result. Optical scattering techniques produce small particles to scatter the source beam, the amount of scatter providing a result for the concentration of parameter under test. For more information regarding the science behind both photometric and turbidimetric analysis technology please visit www.palintest.com/know. The Pooltest 9 Bluetooth is provided with programmed methods for a comprehensive range of water quality parameters. Upon choosing a test the instrument automatically selects the required parameters for accurate analysis including wavelength and reaction time. On completion of some tests optional follow-on tests are available plus results can be converted to alternative units of expression e.g. mg/l to ppm, N or NH3. The Pooltest 9 Bluetooth offers a choice of connectivity to download all or selected results via Bluetooth 4.0 wireless connectivity or USB connection. Bluetooth 4.0 (also known as Bluetooth SMART or Low Energy) connection allows seamless data exchange using the Palintest Aqua Pal app, available for iOS and Android devices. See Appendix 5 for more details. USB connection via the port located at the rear of the instrument provides a choice of either ‘Hard Disk’ mode or serial communication mode. See Section 6.5 for more details. The Pooltest 9 Bluetooth offers a choice of either mains power via the USB port or using three 1.5V ‘AA’ batteries (supplied). The Pooltest 9 Bluetooth is delivered with a two year warranty and a full range of service, calibration and technical support.

6 3.0 Taking a Sample The first critical step in any analysis is taking a representative sample.When selecting a sample point a number of care points are recommended as follows: • Ensure the sample point is safe to access and follow all relevant/required precautions • When sampling from a tap or outlet, remove any attachment and clean the tap/outlet with a dry cloth before allowing to run for 1 minute prior to sample collection • When sampling from a pool or spa take the sample as near as possible to the centre of the pool and at least 20cm below the surface of the water • Rinse any sample container repeatedly with the sample to prevent any cross contamination from previous samples • Once collected the sample must be processed immediately or as quickly as possible, especially for highly reactive species such as chlorine for example. The use of a portable field test kit makes this possible. However if the delay between sample collection and analysis is likely to be several hours chill the sample to preserve and prevent potential sample deterioration • Samples containing solid particles can interfere with photometric analysis. Either allow solids to settle and decant the clear liquid or filter the sample prior to analysis all-guide s.com

The Pooltest 9 Bluetooth provides simple, accurate and reliable analysis of key pool, spa and other aquatic samples. Selecting the required parameter and performing the test are supported through on-screen prompts and comprehensive test instructions. The principle of photometric testing is based on the absorption or scattering of a measured intensity of incident light compared to the light intensity reaching the detector array. The light intensity is determined as Transmittance (%T) or Absorbance (A) and compared to calibration tables stored within the Pooltest 9 Bluetooth. The stored calibration tables convert %T or A to results in a variety of units (mg/l, ppm etc.) as defined in Section 6.6. Calibration tables are defined by Palintest based on the measurement of reference standards using Palintest reagents. To achieve the best quality results there are a small number of care points: 1 Always use the provided light cap to prevent ambient light affecting the results. 2 Ensure Sample and Blank cuvettes are clean, dry and inserted correctly into the sample chamber, using the allocated orientation mark to align. 3 Always blank the instrument with untreated sample prior to analysis. Additional guidance is provided in Appendix 1 Photometric Testing Hints and Tips 6.1 Selecting Test Parameters The Pooltest 9 Bluetooth offers a number of choices to select the parameter to test: Test Number Entry - use the numeric keypad to enter the unique Test Number to directly access any programmed calibration. Direct Entry - use the numeric keypad to directly access the 10 most common tests with a single key push. Choose a Test - the full list of test parameters is available by selecting Choose a Test and scrolling using the up/down keys.When the desired parameter is highlighted, press the OK key to access the method.Tests are presented in Test Number order. When the required test is selected the Pooltest 9 Bluetooth automatically selects the correct wavelength and sets additional method parameters as required. Test method protocols are defined in detail section 8, including the reagents and accessories that may be required. When a test is selected, the Pooltest 9 Bluetooth will display a number of screens and options to guide the user through the testing process, as described in the following pages. 6.2 Dilution Factor If selected in the System menu, the initial screen will request the defined Dilution Factor to apply to results. If Dilution Factor is not active this screen will not be shown. Results shown on the final screen have automatically been corrected for dilution prior to display. Corrected results will also be stored in the log. Note: if the System Lock is applied the Dilution Factor functionality cannot be switched on or off from the current status until the system is unlocked. 6.3 Blanking the Pooltest 9 Bluetooth Blanking the photometer is a key first step in photometric analysis, effectively removing the potential entrained sample colour and minor amounts of turbidity from calculation of analytical results. To blank the photometer, prepare a Blank cuvette using untreated sample i.e. sample that has not been reacted with any reagents. If the sample is to be diluted or physically treated (filtered for example) before analysis, use the same dilution/ treatment for the Blank cuvette.

Bluetooth will request the user to Insert Blank. Insert the Blank cuvette and press OK. The Pooltest 9 Bluetooth will determine the absorbance due to the sample colour at all wavelengths simultaneously and store in temporary memory for use in analysis. Upon successful blanking the Pooltest 9 Bluetooth will automatically move to the Insert sample stage of the analytical method. If the sample is too highly coloured to support effective blanking and subsequent analysis the error message “Error 9 is caused by the blank cuvette being too dark. Check the correct cuvette is being used”. Ensure the blank cuvette is being used, not the sample plus reagent cuvette. Sample colour can be reduced by dilution with clean water; the dilution selected should take account of the expected concentration of parameter under test. Blank results are stored in the temporary memory of the Pooltest 9 Bluetooth and will be used for all subsequent tests until: • The instrument is powered down (temporary memory is lost/deleted) • A new Blank reading is taken - this option is available on accessing any subsequent test at the base of the screen. Repeat the blanking process if the sample changes significantly or a new sample is under test • Some tests use a reversed blanking process where a coloured blank cuvette may be required. When changing between standard tests and ‘reverse blank’ test, a new blank will be requested by the Pooltest 9 Bluetooth. If the blank value generated in this step is not detectable an error message will be displayed “Error 7 is caused by too much ambient light.Try using the light cover provided with the instrument”. See Appendix 1 Photometric Testing Hints and Tips for more advice regarding effective blanking. 6.4 Reading Results with the Pooltest 9 Bluetooth Assuming a suitable blank has been recorded, the next step of the photometric analysis process is to carry out the reading step. Prepare a Sample cuvette following the method instructions provided in Chapter 8. all-guide s.com

At the Insert sample prompt, insert the sample cuvette ensuring it is clean and dry and oriented correctly using the location mark. Press OK to begin the measurement process. The screen will display Reading... At the completion of the measurement process the result is displayed on screen. 6.5 Timer Many photometric methods require a reaction time to develop, the recommended time period being documented in the Palintest Phot Book and included as part of the method parameters programmed into the Pooltest 9 Bluetooth. Tests requiring a reaction time will have the option to select an automatic timer to count down the reaction time required.While in the Insert sample screen use the right key to move the cursor to highlight Timer. The programmed reaction time will be displayed. Press OK to Start the countdown. Three options will be displayed: Stop cancel the countdown timer Exit exits the countdown screen and returns to the Insert sample screen. The countdown will continue and the current time can be seen by selecting Timer.At the end of the countdown an audible alarm will sound to indicate the sample is ready to read. Select OK to read the sample manually. Exit and Read exits the countdown screen and automatically reads the sample at the completion of the allocated time period. 6.6 Changing Result Units of Expression Many chemical species have a number of alternative units that can be used for reporting results e.g. Phosphate can be expressed as PO4 or P for example.

are available the LM symbols will be displayed next to the current result units. Use the up/down arrows to change the units of expression as required.Values are modified automatically. Results stored in the log will be in the units selected on screen, changing the chemical species will add an entry to the log showing the updated result and species parameter selected. 6.7 Follow-on Tests A number of photometric methods have additional optional methods that can be applied, known as Follow-onTests e.g. Phot 008Total Chlorine follows Phot 007 Free Chlorine. Follow-on methods are usually either based on further reagent addition to the sample just measured for sequential parameters or used to correct for potential/known interferences. Follow-on tests are clearly defined in the Section 8 and, if available, are accessed via the Follow-on option located at the right hand side of the options. To access the Follow-on test, highlight Follow-on and press OK. The next method is automatically loaded and operated in the usual manner. NOTE: if no viable result is produced during the first stage of a sequential test method, the Follow-on option will be automatically removed.

protocols for the key parameters required to effectively control swimming pools, hydrotherapy pools, spas and hot tubs. The tests available by number are as follows: Test 1 Chlorine-Free/5 or Chlorine-Free/10 Standard Range: 0-5.00mg/l (ppm) Cl2 (use DPD 1) Extended Range: 0-10.0mg/l (ppm) Cl2 (use DPD XF) Colour change: Colourless - Purple/Red 1 Rinse test cuvette with sample leaving two or three drops in the tube. 2 Add one DPD 1 or DPD XF tablet, crush tablet and then fill the test tube with sample to the 10ml mark.

To determine Water Balance Index, select either Palintest or Langelier from the System Mode prior to commencing. In both Palintest and Langelier test methods, three parameters are measured using the Pooltest 9 Bluetooth in a defined sequence with the result for Water Balance displayed at the test conclusion. Alkalinity (Alkaphot), Calcium Hardness (Calcicol) and pH (Phenol Red) tests are required. Prepare the test solutions as described in the individual parameter test methods and proceed as follows: Palintest Water Balance 1 Select Test 77 by pressing the Alkalinity key (no. 7) twice or from the ‘Choose a Test’ list. 2 Carry out the Alkalinity test then select ‘Follow-On’ from the results screen. 3 Carry out the Calcium Hardness test then select ‘Follow-On’ from the results screen. 4 Carry out the pH test then select ‘Follow-on’ from the results screen. 5 The Water Balance Index is calculated and is displayed. See the table below for more details of the results guidance Note: the Palintest Water Balance test has been calculated for an average heated swimming pool (82°F, 28°C). For unheated swimming pools, subtract 0.1 from the index value obtained. For higher temperature pools and spas, add 0.1 to the index value obtained. Langelier Saturation Index Water Balance To complete the Langelier method, a separate Total Dissolved Solids (TDS) meter is required to provideTDS and temperature values which are entered manually. Prepare the test solutions and proceed as follows: 1 Select Test 77 by pressing the Alkalinity key (no. 7) twice or from the ‘Choose a Test’ list. 2 Carry out the Alkalinity test then select ‘Follow-On’ from the results screen. 3 Carry out the Calcium Hardness test then select ‘Follow-On’ from the results screen. 4 Carry out the pH test then select ‘Follow-on’ from the results screen. 5 Manually enter the TDS reading (in mg/l or ppm) taken using the numerical keys.

calibration certificate validating the performance of the instrument as it leaves Palintest. We recommend annual service and calibration of all photometric instruments in normal use. The Pooltest 9 Bluetooth also includes an automatic routine to validate analytical performance using certified Palintest Check Standards.Accessed via the Mode menu, the Check Standard Mode provides a field method of ensuring your instrument is operating within defined specifications and also a troubleshooting method for unexpected results. Every Palintest Check Standards set is supplied with certified values expressed as %T (Transmission), derived from traceable reference materials.Acceptable tolerances are defined on the certificate and are automatically specified within the Pooltest 9 Bluetooth. 8.1 Check Standard Mode Access Check Standard Mode from the Mode screen. Highlight Check Standard Mode and press OK. Two choices are offered: Enter Check use the up/down keys to Standard Values adjust the displayed values to match the certificate Check Standard insert the Check Standards Measurement in the defined order to generate a validation report 8.2 Enter Check Standard Values Each standard has two values assigned, for two individual wavelengths. Use the up/down keys to adjust the values to match the certificate, following the order defined on the display. Press OK when the correct value is shown and the prompt will forward to the next value. Upon completion the message Check Standard Values assigned successfully will be displayed. Press OK to return to the Check Standard Mode menu. 8.3 Check Standard Measurement Follow the on-screen prompts to insert the Check Standards in the defined order. The Pooltest 9 Bluetooth will automatically measure the Transmittance at the required wavelength. Upon completion of the sequence the results are displayed on screen with pass or fail status. If the Check Standard Mode reports a failure, see Appendix 2 Troubleshooting for guidance or contact your local Palintest supplier.

Photometric analysis is a very powerful technique, providing accurate analysis of a wide range of critical swimming pool, spa, hydrotherapy and hot tub parameters. A complete guide to the science behind photometric (also known as colorimetric) analysis can be found in the Know portal at www.palintest.com/know/ Palintest has focused on simplifying the test methods and equipment used for this technique but there are still a number of ways to ensure the results you generate are as accurate as possible: 1 Always use genuine Palintest reagents when using the programmed test methods. Each parameter has a unique calibration which has been generated using Palintest reagents. Alternative reagents may follow the same general methodology but can differ substantially in formulation and colour generated thereby rendering the calibration and results inaccurate. 2 Always correct for the blank value - any inherent colour in the sample (which may not be visible to the naked eye) will offset the result if the blank step is omitted. If the sample colour is too intense for the photometer to blank use dilution with deionised water to reduce the intensity. Remember to dilute the sample to the same extent for analysis. 3 Always respect the reaction time specified within the instructions. Some methods produce instant colour whereas others require a reaction time to reach full development. Taking a reading before the reaction time has elapsed may lead to low results. 4 The presence of solids, either large or in the form of turbidity, can adversely affect the quality of results by preventing incident light from reaching the detector.The blanking step can reduce the impact of turbidity interference but large solid particles must be removed prior to analysis. Solids can be removed by filtration prior to analysis or, if the solids are settleable and will not lie in the optical path, allowing them to settle in the photometer cuvette can be acceptable. 5 Calibration curves relate transmission/absorbance to concentration to provide result data but not all calibration ranges are linear. Frequently at higher concentrations the curve ‘flattens’ leading to higher potential variability in results. If greater accuracy is required than can be achieved on neat samples then dilution can be used to improve performance. 6 Ensure the photometer cuvette is clean, has no droplets on the outside and is not excessively scratched. Good technique is to wipe the outside surface of the cuvette prior to inserting into the optical chamber to prevent contamination of the optical system. 7 Always use good quality, genuine Palintest cuvettes. Use the orientation mark to ensure repeatable positioning of the cuvette. 8 Maintain the cleanliness of the optical chamber by only inserting clean cuvettes. If the chamber becomes fouled or sample is spilled the base can be removed for cleaning access. Clean the optical chamber with a soft cloth. Do not use abrasive chemicals or scouring agents. 9 Always use the light cap provided to prevent ambient light affecting results.This is especially relevant when operating in strong sunlight or other light conditions. 10 Ensure your Pooltest 9 Bluetooth is operating effectively by using Palintest Check Standards and the Check Standard Mode (see Section 9 Calibration/Validation) and having the photometer serviced and calibrated at regular intervals. Calibration is recommended at 12 month intervals for normal usage and can be provided by your local Palintest distributor. 24

The Pooltest 9 Bluetooth features self-diagnostic software and hardware to optimise performance and battery life.The Info panel indicates the status of the Pooltest 9 Bluetooth and any specific fault conditions are defined and displayed on screen. Optical Errors I have an Error 9 message Error 9 is caused by the blank cuvette being too dark to allow the blanking step to be carried out. Check that the correct cuvette is being used i.e. ensure the sample cuvette is not being used for blanking. If the sample is too highly coloured or contains significant solids, dilute and repeat the blanking step. If the problem persists and the blank cuvette is not the issue, clean the optical chamber by removing the access cover and cleaning with a soft cloth. Do not use corrosive or abrasive chemicals. I have an Error 7 message Error 7 is caused by too much ambient light reaching the detector. Use the light cover provided with the instrument. Check Standard Issues How do I maintain my Check Standards? Check Standards are manufactured to precise values/tolerances, certified against traceable reference materials and provided in sealed cuvettes. Do not decant or remove the sealed cap from the Check Standard. Ensure the Check Standard cuvettes are clean and dry using lint-free cloths before inserting into the optical chamber. Insert the Check Standard aligning the orientation arrow towards the front of the optical chamber. Values assigned to calibration standards are defined at 20-25°C. Extremely high or low ambient temperatures can affect Check Standard results so ensure standards are at the defined temperature to effectively validate. Check Standards have a two year shelf-life, after which the colours will no longer be valid. Please dispose of the expired standards after this period according to the MSDS. My Check Standard validation has failed Photometers may fail the Check Standard validation step due to the requirement for service/calibration. Contact your local Palintest partner for service and support. Ensure the Check Standards are inserted correctly, using the orientation mark to align and inserted fully. Use the light cap to prevent any ambient light interference. Service/calibration is recommended at annual intervals in normal operation.
