LM YN Digital AC Voltmeter AC80-300V Frequency Counter

LM YN Digital AC Voltmeter AC80-300V Frequency Counter 45.0-65.0HZ LCD Display Voltage Frequency 2 in 1 Meter Tester
- 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,This voltmeter is designed using the principle of capacitor step-down. Because the higher the frequency, the smaller the impedance of the capacitor, so it is not suitable for high-frequency electronic speed regulation, unconventional AC sine wave frequencies, or other high-frequency equipment. Otherwise, it may appear inaccurate test or damaged voltmeter.
- Two wires direct connection, standard installation size, can work under extreme environmental condition.
