36 8 Troubleshooting Problems Causes Remedies After calibration, the instrument produces abnormal measurement results. The gas container is improperly connected. Vacuum pressure is being applied on the exhaust tube. Pressure is being applied on the exhaust tube. The connected gas container contains gas components other than the calibration gas. An improper calibration gas has been selected. The component ratio of the calibration gas has been set improperly. The regulator has been set to an improper pressure. Check the connection between the gas container and the instrument or the gas pressure of the gas container. Check the exhaust tube connection and condition. Select and set up a calibration gas properly and redo the calibration *3. Contact your local distributor. *1: Error message: "WARNING! : FROM Data Error", "WARNING! : EEPROM Error", "WARNING! : Signal Level Error" *2: Error message: "sample gas is not detected!", "MEASUREMENT FAILURED!", "CALIBRATION FAILURED" *3: Turn the power ON with the CAL key held down to return the instrument to the state before the calibration (the state before shipment). 28 TASCO JAPAN CO., LTD.

For details, refer to " 4 Calibration method " (page 14). Other gases have already been calibrated before shipment. WARNING Combustible gases hazard Combustible gases should not be applied to TA400A.There is no sensor for combustible gases built in TA400A, so there is a high risk of a possible explosion of the exhausted combustible gas when in contact with air after measurement. Note TA400A can only detect six single refrigerants (R12, R22, R32, R125, R134a, and R143a) and mixed refrigerants consisting of the mixtures of the above single refrigerants. Even when refrigerants other than the six single refrigerants are contained in the sample, the ratio of the refrigerants will automatically be divided proportionally among the detected single refrigerants so that the total percentage would add up to 100%. Likewise, there is also a possibility that the interference of the non-measurable gas would affect the outcome of the measured result. 30 TASCO JAPAN CO., LTD.
