4.2 Calibration Errors, Trouble shooting and Remedies
Error 1: Sensor Zero too high.
The microprocessor was unable to make initial adjustment. The output from
the sensor-element is too high to adjust. This error can occur during step 4
of the calibration procedure. A short sensor-element could result in this
error. Check if sensor wires are connected properly and firmly to the sensor
terminals.
Error 2: Sensor Zero too low:
The microprocessor was unable to make initial adjustment. This error can
occur during step 4 of the calibration procedure. Check if the sensor wires
are not loose and are connected properly to the terminals.
Error 3: Calibration Time Out:
After initial adjustment the unit waits maximum of 60 seconds for the
calibration gas. Calibration is aborted if no calibration gas is detected by the
microprocessor. Check for the leaks in the calibration apparatus and check
the flow rate. Always use a calibration adapter and proper flow rate. A
completely dead sensor could also result in this error.
Error 4: Not enough Sensor reaction to gas:
At the end of the calibration cycle the microprocessor checks for the
adequate sensor reaction to the calibration gas. This error code is
displayed when sensitivity of the sensor to the calibration gas applied is
extremely low and the microprocessor is unable to make final adjustments.
This error can also occur when there is insufficient flow of the calibration
gas to the sensor. Also check if the calibration gas has not expired and be sure to use the
calibration adapter and check the calibration apparatus for leaks.
