9. During measurement the EXA adjusts the measuring frequency to give the best conditions for the actual value being measured At low conductivity there is a risk of error due to the capacitive effects of the cable and the cell These are reduced by using a low measuring frequency At high conductivity the capacitive effects become negligible and errors are more likely to be caused by polarization or fouling of the cell These errors are decreased by increasing the measuring frequency At all values the EXA checks the signal from the cell to search for distortion which is typical of capacitive or polarization errors If the difference between pulse front and pulse rear is gt 20 an error E1 will be displayed and the FAIL flag in the display is activated In service code 05 it is possible to turn this check on and off 12D08B02 01E 8 2 Troubleshooting The following error message table gives a list of possible problems that can be indicated by the EXA Table 8 1 Error Codes Error description Possible cause Suggested remedy Polarization detected on cell Sensor surface fouled Conductivity too high Clean sensor and calibrate Replace sensor Temperature coefficient out of limits 0 3 5 C Calibration out of limits Matrix compensation error Incorrect field calibration of TC Calibrated value differs more than 20 of nominal value programmed in code 03 Wrong data entered in 5x5 matrix Re adjust S
