Matters needing attention

1. Before use, the meter needs to be powered on for 15 minutes.

2. Pay attention to prevent vibration and impact, and do not use it in places with excess dust and excess harmful gases.

3. The input wire should not be too long. If the input end of the signal under test is long, please use a twisted pair shielded wire.

4. If the signal is accompanied by high frequency interference, a low frequency filter should be used in the line.

5. When not in use for a long time, please turn on the power for no less than 4 hours every three months.

6. Long-term storage should avoid direct light, and should be stored at -10℃~70℃.

7. If there is no display on the meter, first check the auxiliary power supply to see if the voltage is within the specified range.

8. If the display is abnormal, check whether the input signal is normal and whether the signal terminals are tightened.

9. Unless the PT has enough power, the PT signal cannot be used as an auxiliary power supply at the same time to ensure the normal operation of the instrument.

10. The screws of the current terminals in the CT circuit must be tightened to ensure reliable contact between the incoming and outgoing wires to avoid malfunctions.
