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 connectedtoPT3, testtransformer 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. Whentheinstrument is notworking properly, first check the power fuse is blown. After replacement of the same model can continue the insurance experiment. If the problem is more complex, please contactmedirectly.

5, The instrument must not be placed in humid and high temperature environments.

6, The instrument is not used as a long time (more than three months), the battery will run out of damage, so each interval of 3 months should be given to the instrumentonecharge(6 hours or more), in order to ensure that the instrument can be used normally. Charging steps: Turn the power switch, plug in 220V power until the battery is indicating below the LCDscreen90% ormore.
