Tips for using the digital panel volt meter

Before use, the digital panel volt meter needs to be powered on for 15 minutes.
Pay attention to prevent vibration and impact, and do not use this meter in places with excessive dust and excessive harmful gases.
The input wire should not be too long. If the input terminal of the signal under test is long, please try a twisted-pair shielded wire.
If the signal is accompanied by high frequency interference, you should try the low frequency filter online.
When it is stored for a long time and not in use, please turn on the power once every three months for not less than 4 hours.
For long-term storage, avoid direct light, and should be stored at an ambient temperature of -25°C ~ 55°C.
If there is no display on the digital panel voltmeter, first check the auxiliary power supply and whether the voltage is within the range.
If the display is abnormal, check whether the input signal is normal and whether the signal terminal is tightened.
Unless the PT has enough power, the PT signal cannot be used as an auxiliary power source at the same time to ensure the normal operation of the instrument.
The current terminal screws in the CT circuit must be tightened to ensure reliable contact between incoming and outgoing wires to avoid malfunctions.
If you want to calibrate the voltmeter, the calibration instrument should be better than 0.1 level to ensure calibration accuracy.
