VII. Installation and Maintenance Key Points Installation steps

The equipment should be placed on a stable desktop or fixed to a standard rack, ensuring good ventilation and being away from strong heat sources and strong electromagnetic equipment;

Connect to a 100-240V AC power supply and confirm that the power voltage matches the rated voltage of the equipment;

Connect the tested circuit: connect the voltage terminals in parallel to the tested circuit, and the current terminals in series to the tested circuit, ensuring that the connections are firm and the insulation is good;

If communication is required, connect the RS232/RS485 interface to the upper computer and configure the communication parameters (baud rate, address, etc.);

After powering on, the LED screen lights up, the equipment enters the measurement state, and the range and alarm threshold can be set according to the requirements.

Daily maintenance

Regularly (every 3 months), after power off, use a dry soft cloth to wipe the surface of the machine body, the connection terminals and the communication interface, remove dust and oil, and avoid liquid cleaners from invading the equipment interior;

Check the tightening status of the connection terminals to prevent loosening from causing poor contact or measurement errors;

Avoid long-term exposure to high temperature, high humidity, and strong corrosive environments, maintain ventilation and heat dissipation of the equipment to extend its service life;

Regularly check the communication interface to prevent oxidation that may cause communication interruption; if necessary, use alcohol cotton swabs to wipe the interface contacts.

Common fault troubleshooting

Screen does not light up: check if the power connection is normal, if the power adapter is damaged, and if the power socket is powered on; troubleshoot the equipment power circuit faults.

Measurement data fluctuates greatly: check if the connections are firm, and if there are strong interferences in the tested circuit; confirm that the equipment is well grounded and is away from interference sources such as frequency converters and motors; switch to the appropriate range and try again.

Communication failure: check if the communication line connection is correct, if the interface is oxidized; verify if the communication parameters (baud rate, address, protocol) of the upper computer and the equipment are consistent; replace the communication line and try again.

Alarm triggered mistakenly: check if the alarm threshold setting is reasonable; troubleshoot if there is instantaneous voltage/current fluctuation in the tested circuit; calibrate the equipment measurement accuracy.
