What causes Err. 6 (Zero Point Error) on YOKOGAWA Measuring Instruments?
Err. 6 (Zero Point Error) may be caused by chlorine entering the chlorine-free water used for calibration (when the chlorine-free-water-based measuring method applies), or the indicator electrode or counter electrode may be defective. Confirm if any of these is the cause.
What should I do if I get Err. 10 (Converter failure) on YOKOGAWA FC400G Measuring Instruments?
The FC400G free available chlorine analyzer has become defective. Contact Yokogawa service.
What does NOTE. 02 (Input Data Setting Error) indicate on YOKOGAWA Measuring Instruments?
If NOTE. 02 (Input Data Setting Error) appears, the relevant data will not be updated. Set correct value again.
What does NOTE. 01 (Input Data Setting Range Exceeded) mean on YOKOGAWA Measuring Instruments?
If NOTE. 01 (Input Data Setting Range Exceeded) appears, the relevant data will not be updated. Set correct value again.
What does NOTE. 03 (Input Data Setting Error) mean on YOKOGAWA Measuring Instruments?
If NOTE. 03 (Input Data Setting Error) appears, the relevant data will not be updated. Set the correct value again so that the mg/l (or ppm) value for 100% signal output exceeds the value for 50% signal output.
What to do if I see Err. 4 (Applied Voltage Error) on YOKOGAWA FC400G Measuring Instruments?
If you see Err. 4 (Applied Voltage Error), confirm if the applied voltage parameter value set in service code 07 is correct.
How to resolve Err. 1 (Diffusion Current Value Exceeded) on YOKOGAWA FC400G Measuring Instruments?
To resolve Err. 1 (Diffusion Current Value Exceeded), confirm if the applied voltage parameter value set in service code 07 is correct. Also, confirm that there is no grime or moisture adhesion resulting in insulation deterioration on the electrode cable connection.
How to troubleshoot abnormal analog output on YOKOGAWA Measuring Instruments?
To troubleshoot abnormal analog output: * Reduce the lead resistance to 550? or less. * If the output circuit is abnormal, contact YOKOGAWA.
What to do for Err. 8 (Temperature Compensation Range Exceeded) on YOKOGAWA Measuring Instruments?
To address Err. 8 (Temperature Compensation Range Exceeded), control the sample temperature to be in the range of 0.0 to 40.0°C.
How to resolve Err. 7 (Response Error during Zero and / or Span Calibration) on YOKOGAWA FC400G Measuring Instruments?
To resolve Err. 7, confirm response recovery after polishing the indicator electrode with alumina. Also, check that the stability determination parameters “*?T. SEC”, “ *?PPM ”, and “*CT.min” set in service code 04 are correct. If the parameters are correct but there is still no response recovery, the indicator electrode may have deteriorated and should be replaced.
