LM YN Digital AC Voltmeter AC80-300V Frequency Counter 45.0-65.0HZ LCD Display Voltage Frequency 2 in 1 Meter Tester

LM YN Digital AC Voltmeter, AC80-300V Frequency Counter, 45.0-65.0HZ LCD Display Voltage Frequency Meter

Parameters: Accuracy: 1 2 digits . Display: LCD displayer . Measuring Range: AC 80-300.0V . Testing Frequency: 45-65.0Hz . Measuring Velocity: 2 times/sec . Product Size: 70 mm x 40 mm x 30mm LWH . Extreme Working Condition: Operating Temperature: -10 +50 . Operating Humidity: 10 80%(no condensation) . Working Pressure: 80 106kPa . Sunlight Irradiation: No . Note: 1.Needn't power supply: you can dirrectly connect two wires to the tested voltage to measure voltage and frequency . 2.This meter is 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.. Package Included: 1 Digital AC Voltmeter AC80-300V Frequency Counter 45.0-65.0HZ LCD Display Voltage Frequency 2 in 1 Meter Tester If you for any reason are not happy with any product supplied , please do not hesitate to contact us and we will do our best to solve your problem .

Key Features

• ✅ 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.
