Feature

2 in 1 meter which can measure AC voltage and frequency simultaneously, with potentiometer for frequency calibration, turn the screw clockwise to increase frequency and turn the screw anticlockwise to reduce the frequency.

It can directly connect two wires to the tested voltage to measure voltage and frequency without power supply.

It is for testing AC 80V to 300V with high accuracy and high working efficiency of 2 times/s measuring speed.

Only suitable for AC45-65Hz mains supply, can't be used for measuring circuit of square wave, inverter output and sine wave.

Two wires direct connection, standard installation size, can work under extreme environmental condition.
