3、 Installation and usage precautions
When stored for a long time without use, please power on for at least 4 hours every three months.
If the instrument does not display, the auxiliary power supply should be checked first to ensure that the voltage is within the range.
The input wire should not be too long. If the input end of the tested signal is too long, please try using twisted pair shielded wire.
If the signal is accompanied by * frequency interference, a low-frequency filter should be tested online.
Remove the instrument and install the card;
Before use, the instrument needs to be powered on for 15 minutes.
To calibrate instruments, the calibration instrument should be better than level 0.1 to ensure calibration accuracy.
Unless the PT has sufficient power, the PT signal cannot be used as an auxiliary power source to ensure the normal operation of the instrument.
Insert the instrument into the installation hole of the distribution cabinet;
If the display is abnormal, check if the input signal is normal and if the signal terminals are tightened.
