Usage tips:

Application: This meter is only suitable for pure AC 45-65Hz power supply, can not be used for square wave, inverter output and modify the sine wave sine wave circuit measurement (it can't be used for measuring the AC power converted from a DC power with an inverter), otherwise the meter will damaged!

Install method: you can dirrectly connect two wires to the tested voltage to measure voltage and frequency .

Package includes:

1 x AC voltage frequency meter
