What to do if ADCMT 823B Measuring Instruments displays OL?
- AAshley GreenAug 10, 2025
If the ADCMT Measuring Instruments displays 'OL', it indicates that the input power is too high or the input value exceeds the maximum value set in the specified manual range. Try reducing the input power. Alternatively, if the manual range is set, change to the automatic range.
