Installation and Wiring
Correct installation and wiring are prerequisites for ensuring the normal operation of the 7D2C. Please operate as follows:
- Confirm that the power supply matches the instrument nameplate, and disconnect the power.
- Fix the instrument in a suitable position, avoiding strong vibration and corrosive environments.
- Connect the power and signal wires according to the wiring diagram in the manual, paying attention to polarity.
- After checking that the wiring is correct, turn on the power.
Calibration and Maintenance
Calibration Steps
- Preheat the instrument for at least 15 minutes.
- Connect a standard signal source and input the zero and full-scale signals in sequence.
- Adjust the zero and span potentiometers so that the output matches the standard value.
- Repeat the verification until the error is within the allowable range.
Daily Maintenance
- Regularly check whether the wiring is loose or oxidized.
- Keep the instrument surface clean to avoid dust accumulation affecting heat dissipation.
- Perform an accuracy verification every 12 months.
Common Problems and Precautions
- No output: check the power and signal wire connections.
- Output fluctuation: check whether the grounding is good and eliminate interference sources.
- Abnormal display: confirm that the power supply voltage is stable; contact the manufacturer if necessary.
