Used to select one of a range of pH and Millivolt values. The Function switch must be set to ON or Impedance for the pH/mV output to be active. See sections 2 and 3. Conductivity / TDS Output Selector Used to select one of a range of Conductivity and TDS values. The values are simulated by a precision resistor network, so the Function switch can be left in the OFF position for these tests. See section 4. Function Switch Used to select ON / OFF, Impedance (section 7) or Battery Test (section 8). pH / mV Output Connector All pH and Millivolt signals are output through this connector. Conductivity / TDS / Temperature Output Connector All Conductivity, TDS and Temperature signals are output through this connector.

1. Obtain the correct pH / mV output cable for the instrument under test. 2. Connect one end of the pH / mV output cable to the WP-Sim and the other end to the instrument under test, as per the example diagram below… 3. Switch the WP-Sim Function switch to ON. Switch the instrument under test on and select pH mode. See the instrument’s handbook if necessary. 4. Use the pH / mV selector to output any of the 5 simulated pH values. The readout of the instrument under test should approximately correspond to the simulated pH value selected on the WP-Sim. Variations are possible due to the current temperature and calibration settings of the instrument under test. Please note that the simulated values are for 25 OC.

1. Obtain the correct pH / mV output cable for the instrument under test. 2. Connect one end of the pH / mV output cable to the WP-Sim and the other end to the instrument under test, as per the example diagram below… 3. Switch the WP-Sim Function switch to ON. Switch the instrument under test on and select Millivolt mode. See the instrument’s handbook if necessary. 4. Switch the pH / mV selector to 650 mV. The readout of the instrument under test should be approximately 650 mV. Variations are possible due to the current calibration settings of the instrument under test.

1. Obtain the correct Conductivity / TDS output cable for the instrument under test. 2. Connect one end of the Conductivity / TDS output cable to the WP-Sim and the other end to the instrument under test, as per the example diagram below… 3. The WP-Sim does not need to be switched on for Conductivity or TDS output. Switch the instrument under test on and select Conductivity or TDS mode as required. See the instrument’s handbook if necessary. 4. Use the Conductivity / TDS selector to output any of the 4 simulated Conductivity or 2 simulated TDS values. The readout of the instrument under test should approximately correspond to the simulated Conductivity or TDS value selected on the WP-Sim. Variations are possible due to the current temperature and calibration settings of the instrument under test. Please note that the simulated values are for 25 OC.

1. Obtain the correct Conductivity / TDS / Temp output cable for the instrument under test. 2. Connect one end of the Conductivity / TDS /Temp output cable to the WP-Sim and the other end to the instrument under test, as per the example diagram below… 3. The WP-Sim does not need to be switched on for Temperature output. Switch the instrument under test on and select Temperature mode. See the instrument’s handbook if necessary. 4. The output will correspond to the current temperature inside the WP-Sim. Variations are possible due to the calibration settings of the instrument under test. all-guides com

This section is applicable to combination pH and ORP pool controllers, such as the poolCHEM series, easyCHEM 770 and easyCHEM 660. 1. Obtain the correct Pool Controller output cable for the instrument under test. 2. Each end of the cable is labelled as the WP-Sim or Pool Controller end. Connect the cable to the WP-Sim and the pool controller correctly, as per the example diagram below… 3. Switch the WP-Sim Function switch to ON. Switch the instrument under test on. Continued over the page…

readout of the instrument under test should approximately correspond to the simulated values selected on the WP-Sim. In addition, the pool controller will display the current temperature inside the WP-Sim. Variations are possible due to the current calibration settings of the instrument under test. Note : As the WP-Sim is simultaneously outputting pH and mV values, you will notice that BOTH readings on the display change when the pH / mV selector is changed. Please disregard the pH values when the WP-Sim is set to 650 mV, and disregard the mV reading when the WP-Sim is set to a pH value.

Testing a pH meter with simulated pH values only checks for the accuracy of the input circuit. It does not check for the impedance of the input circuit. The input impedance must be extremely high to match the pH sensor. If the input impedance has been reduced due to component failure, corrosion etc, accuracy will be affected and the pH sensor may suffer permanent damage. To test the impedance of the pH meter’s input circuit… 1. Obtain the correct pH / mV output cable for the instrument under test. 2. Connect one end of the pH / mV output cable to the WP-Sim and the other end to the instrument under test, as per the example diagram below… 3. Switch the WP-Sim Function switch to ON. Switch the instrument under test on and select pH mode. See the instrument’s handbook if necessary.

The readout of the instrument under test should approximately correspond to the simulated pH value selected on the WP-Sim. Variations are possible due to the current temperature and calibration settings of the instrument under test. Please note that the simulated values are for 25 OC. 5. Make a note of the reading obtained on the display. 6. Now switch the WP-Sim Function switch to Impedance. The pH value on the instrument’s display should change by less than 0.05pH if it’s input impedance is high enough. If the display changes by more than this amount, the instrument must be returned for repair.

The WP-Sim is equipped with a Battery Test function. To check the battery, set the Function switch to Battery Test. The red light on the front panel will glow brightly if the battery is OK. If the light is very dim or does not operate at all, the battery must be replaced. all-guides com

1. Turn the instrument over and locate the 6 Instrument Case Screws on the rear. See the diagram below. 2. Remove all 6 screws and open the WP-Sim. CAUTION : THERE ARE WIRES THAT CONNECT THE CIRCUIT BOARD TO THE CONNECTORS. TAKE CARE WHEN OPENING THE METER TO ENSURE THESE WIRES ARE NOT BROKEN. Do not lose the nylon washers, as these form a part of the waterproof seal when the screws are replaced. 3. Replace the battery with a new alkaline 9V battery. 4. Re-fit the rear of the WP-Sim and replace the Instrument Case Screws.

It is your responsibility as the sender to ensure that TPS receives the unit. Please check that the following is enclosed with your equipment: • Your Name and daytime phone number. • Your company name, ORDER number, and return street address. • A description of the fault. (Please be specific.) (Note: "Please Repair" does NOT describe a fault.) Your equipment will be repaired and returned to you by air express where possible. For out-of-warranty units, a repair cost will be calculated from parts and labour costs. If payment is not received for the additional charges within 30 days, or if you decline to have the equipment repaired, the complete unit will be returned to you freight paid, not repaired. For full-account customers, the repair charges will be debited to your account. • Always describe the fault in writing. • Always return the sensors with the meter.
