## Customer Reviews

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

Good looking unit. Very accurate. EZ install.

### ⭐⭐⭐⭐⭐ Functions well
*by J***N on July 20, 2023*

Simple and easy to use

### ⭐⭐⭐⭐ 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 1192) 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.
