can be selected freely on the display. To change the position or the composition, please proceed as follows: -with / / activate the first line on the display -choose with curser key the measured or calculated value -with activate the next line on the display and so on -with or in the last line you leave this process. The values for CO2, Efficiency, Losses, Lambda and the Dew Point are calculated values. They just can be calculated when realistic figures for the basic values like O2 and the temperature are available. It must be assured that: O2 < 20,5 % and T.Gas – T.Air > + 5°C The dew point can just be calculated correctly if in the menu “Ad- justments / Air pressure” the current barometric air pressure has been entered. If the combustion gas temperature falls below the dew point /between 25 and 65°C) the efficiency will be calculated with condensation gain. In this case a (C) is displayed behind the effi- ciency . Correct measurement values are displayed after a delay of 1 to 1,5 minutes necessary for the gas transport to the sensors and to establish a stable electrochemical reaction in the sensors. For stor- age and printing wait for the values to become stable. If the gas val- ue still fluctuates for more than 2 ppm, the reason could be in an unstable draft condition in the gas channel. Once the measurement values are stable and the results can be printed, press to transfer the values to the tem- porary memory. Data will be stored here for later printout (the values of the temporary memory could be checked by pressing / / . While check- ing the values the gas pump will be switched off in order to spare the sensors. (back with ).

10.1. Communication The menu „Data processing“ allows the selection of the following functions: Select: This sub-menu enables to search for or create a data record for the allocation of measurement values (see chapter 3.). Look at: The recorded values of the selected data record can be viewed (see chapter 3.). Load data: Possibility of data import e.g. from ecom software (available at „www.ecom.de“ - check the transfer options of your software). Proceed as follows: 1. Connect instrument and PC with a current RS232 cable. 2. Select “Load data“ and confirm with . 3. Answer following question with Yes (select with cursor keys). 4. Start the data transfer at the PC. Send data: The date record completed with values can be transferred to the PC program using this function (procedure identical to „Load data“). Format: This function is normally only needed by the initial adjustment of the instrument by the manufacturer (preparation of internal memory to data receipt). Caution: All recorded values will get lost! Data processing Select Look at Load data Send data Format memory Continue with : ↑↓ ↵↵↵↵

To display and storage of measured values, the "ecom Connect App" for smartphones (iOS or Android) is available. Test results are stored along with customer information in a pdf-file and can be sent f.e. as email attachment. Links to free download of the Apps can be found on the ecom website.

To secure the accuracy of your measuring instrument we recom- mend the annual check by an authorized ecom partner. In the case of strong demand (e.g. permanent several hours of measurement per day, rough conditions etc.) shorter intervals between checks should be selected - please contact your ecom partner. All ecom partners are listed under www.ecom.de. Do not use other sensor than supposed by our factory and be aware that service done by service stations not authorised by ecom will lead to expiration of any warranty. The following tips for the daily care of accessible parts and compo- nents should be helpful: Condensate pad Regularly check the condition of the condensate pad. It should be changed: - If it is soiled darker than no. 3 on the soot scale - If its extension is on mark "MAX" Replace the condensate pad as follows: 1. Remove hose from the cap and unscrew the cap 2. Unscrew the retaining bolt with spring 3. Replace old condensate pad against new 4. Scew on retain bolt with spring again 5. Scew on cap and replace the hose to the cap Condensate pad

with fresh air. The instrument permanently monitors the condition of the sensors. New sensors wear out from use in time due to reaction (O2-sensor) and due to soiled gases respectively gases in concen- trations beyond the nominal range (toxic sensors). The output values of the sensors are (see menu “Control”): O2 approx. 1500 mV CO 0 mV (+/- 30) If an error message is displayed during calibration cycle and does not disappear after repeated calibrations the instrument must be send to a service centre. The O2 sensor should show > 200 mV, otherwise it should be changed. The CO-sensor is protected by the internal program for overload. In case the limit of 4000 ppm is exceeded the gas pump is switched off. Power supply The battery ensures a main power independent operation. The bat- tery is automatically charged when the instrument is connected to the main power supply. (Please do not interrupt the charging shortly since the charging circuitry could operate faulty.) The recharge of the battery should be done in any case if the voltage display (menu “Control”) is less than 5.8 V (Instrument will stop working at 5.5 V). Sampling probe and hose Depending on the frequency of use the probe and the hose must be cleaned regularly, thus in order to prevent particles from lodging and early ware due to corrosion. The hose can be cleaned after all connections on the instrument and the probe itself have been switched off (use warm water and then blow out to dry)

ment information? How long is the life span of the sensors? Which sensors can I exchange? The instrument shows the error message „O2 sensor 0 mV“! The instrument shows the mes- sage „Check required“! The instrument shows the error message „T-Gas“ oder „T-Air“! The instrument shows wrong or inaccurately CO2 values! In the menu „Control“ all important instrument infor- mations are shown (e.g. accu voltage, sensor values, unit number, next service date, operation hours etc.). With the arrow keys stands you can switch to the second page. The life span depends on the operating hours and the instrument equipment. The life span of the toxic sensors (CO, NO, SO2, NO2) is affected by high gas concentrations and a not sufficient purging. The life span for these sensors amounts to on the average between 4 and 6 years. The life span of the O2 sen- sor is independent of the operating hours and amounts to approx. 4 years. Please contact the next authorised service centre for changing sensors. The sensor must be renewed. This message appears automatically every 12 months or after 250 operating hours. Note: This is a recommendation to let check the instrument. The instrument is however still ready for use. Possible reasons could be: - Cable is broken (at the plug) - T-Air sensor is broken - Thermocouple is broken - Cable is defective Note: The error messages can be ignored at the B by pressing „Enter“. Calculations that depends on these temperatures are not implemented. Possible reasons could be: - O2 is defective (CO2 values are calculated from the O2 values) - Pump is not working correctly - Leakage in the gas way - condensate trap / gas cooler is clogged

exchanging the accessories (probe, hose, temperature sensor etc.). If further questions or problems should arise, please contact the next authorised ser- vice centre. My instrument cannot be switched on! My instrument does not print! Can I change the printout? - Please check the mains cable - Please check the fuse - Please check mains connection (Plug socket switched on?) - Please load the accumulator min. 8 hours (Accumulator could be over-discharged) Please check whether the printer paper is correctly inserted. The thermal printer writes only on the ther- mally sensitive side. Please use always the correct paper for the printer, you will prevent defects at the printer. Please make sure that the printer is clean (no chads in the drive). You can change the printout (Menu: “Adjustments”).
