Product information

1, Taken from the PT secondary voltage reference, you should carefully check the wiring to avoid PT secondary circuit.

2, The voltage signal input line and the current signal input line must not be reversed, if the current signal input line connected to PT3, test transformer secondary side or measuring end, it may burn the instrument.

3, Where the input voltage and input current circumstances, do not plug the measuring line, so as not to burn the instrument.

4, The instrument is damaged, stop using it immediately and notify the Company and do not repair yourself out of the box. When the instrument is not working properly
