## Description

This AC voltage frequency meter can atuo detect the real time voltage and frequency. Perfect meter to monitor RV or home generator and shore power. Just what you need to add-on for your generator. It's a good reminder. Wide working voltage range, AC 80-500V Frequency measuring range 45-65Hz Two wires design Easy to use, connect two wires directly, the meter can automatically detect the accurate real-time voltage and frequency " Clear and bright LED digital display, much better than LCD Low power consumption Small size and portable, very convenient Widely used in different modes of gasoline engine generator, diesel engine generator, motor and RV Technical Parameters: Working voltage: AC 80-500 V Working frequency: 45-65 Hz Measurement speed: 2 times/s Measuring Accuracy : 1%±2 digits Operating Temperature: -10～+50℃ / 10℉~122℉ Operating Humidity: 10～80%(no condensation) Working Pressure: 80～106kPa Display: LED displayer(Red&Green) Material: ABS Product dimensions(WxDxH):2.75"x1.18"x1.57"/ 7x3x4cm Net weight:1.3oz/36g 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

Review: Accurate Easy To Read - After destroying my plasma cutter it was necessary to know the frequency & voltage of my portable generators. This meter instantly solved my problem. I tested it first on my oscilloscope and another known accurate meter and it was exact. Rather than modify my generators, I made a small mounting panel for it to attach to the frame. Then wired it directly to the back of one of the outlets. It's easy to read in bright sun and even looks good. Cheap insurance for valuable electronics and equipment. I wish I had the sense to buy & install this before I had a problem. Absolutely, I'd buy it again!
Review: Works good. Looks good. - Good looking unit. Very accurate. EZ install.

### ⭐⭐⭐⭐⭐ Accurate Easy To Read
*by J***P on October 11, 2023*

After destroying my plasma cutter it was necessary to know the frequency & voltage of my portable generators. This meter instantly solved my problem. I tested it first on my oscilloscope and another known accurate meter and it was exact. Rather than modify my generators, I made a small mounting panel for it to attach to the frame.

### ⭐⭐⭐⭐⭐ Works good. Looks good.
*by M***N on July 18, 2024*

Good looking unit. Very accurate. EZ install.

### ⭐⭐⭐⭐ DONT PRESS THE WHITE BUTTON ON THE BACK PANEL (see item 2 below)
*by W***N on May 3, 2021*

The meter does work. I dinged the product 1 star for two reasons: 1) The first one was not calibrated and was reporting 121 volts - actual was 119 2) It does not come with documentation, Yes it only has two wires that connect to the line voltage, *HOWEVER* there is a white pushbutton on the rear panel. Once presse it will put your device into calibration mode, and the device is useless unless you know what to do next. Fortunately the vendor was able to provide the following instructions (which do work): QUOTE: Long press the key to enter the frequency fine-tuning mode, and then increase the frequency by 0.1 for each press, cycle for 20 words (equivalent to +/- 10 words, +/- 1HZ), and then press the key for long time to save when reach the target value. Long press button to save and into voltage fine-tuning mode, then every click, voltage up to add 0.1, loop 30 words (equivalent to +/- 15 words, +/- 15v) NOTE, the adjustment range is a circular process, without addition or subtraction; But each time there may be a different scope.
