What to do if dacell Measuring Instruments display shows 'OVER' or 'UNDER'?
If the dacell Measuring Instruments display indicates 'OVER' or 'UNDER', it could be due to a defective sensor, an open or short in the sensor's input/output line, or another issue. First, check the sensor wiring. If that doesn't resolve the problem, check the connection to the sensor. If the issue persists, consider exchanging the sensor for a new one.
Why does my dacell Measuring Instruments display drifts?
Display drift in dacell Measuring Instruments can stem from several causes: a defective sensor, AC noise in the power line, a faulty connection to the sensor (introducing noise), or an incorrect input filter setting. To address this, start by checking the sensor state and output. Then, examine the power line and connection for AC noise. Next, verify the connection to the sensor. Finally, check the filter DIP switch to ensure it is correctly set.
Two calibration systems: actual load and rated sensor output (mV/V).
User can select between peak hold and sample hold modes for data retention.
Configure limit values via front panel keys and output contact signal from the rear panel.
Setup values stored on flash memory, retaining data after power interruptions.
Automatic reset function to counter system halts caused by external factors like electrical noise.
Ensure proper installation environment: avoid wetness, vibration, high temp/humidity, direct sun, dust, salt/ion. Ground properly.
During calibration, do not input unstable loads. Avoid pressing keys at discretion.
