6. Troubleshooting 39 6. Troubleshooting 6.1 Check Power Symptom Even when the power switch is turned ON, on-screen display does not appear or display goes off quickly. Possible Cause / Solution Refer to - When using battery: The battery is exhausted. => Turn the power off and charge the battery. 4 - When using AC adapter: The dedicated adapter is not being used. => Make sure to use the dedicated AC adapter.
6. Troubleshooting 40 6.3 Zero Check Symptom Zero is not stable Zero adjustment cannot be performed. Possible Cause / Solution Refer to Rubber cap may not be put on the inlet or may not be inserted properly. Put the rubber cap on properly. 2 Filter may be clogged. Replace the filter with a new one. 35 Inside the optical system may be dirty. Relatively light particles such as carbon or resin could enter inside the optical system, which could result in Zero point rise.
6. Troubleshooting 41 6.5 Calibration Check Symptom ZERO cannot be adjusted. (BACK GROUND) Sensitivity cannot be adjusted. (SPAN CALIBRATION) Possible Cause / Solution The zero adjustment range may exceed the specified range. If the ZERO adjustment range exceeds the standard range ± 20 counts before shipping, it is a calibration error. Please contact your distributor or KANOMAX service center for repair. The sensitivity may be beyond the specified sensitivity adjustment range.
6. Troubleshooting 42 6.7 Pulse Output Symptom There is no output. The output signal level is wrong. Output value exceeds the specified value. Possible Cause / Solution The plug may not be firmly inserted into the output terminal. The dedicated output cable must be used. The instrument may not be used within the rating (voltage and current). The polarity may be wrong (+, -). The instantaneous value may exceed the concentration equivalent to 10,000 CPM of the instantaneous value. Refer to 31 31 31 6.
