## Description

Main Specifications: CALIBRATABLE: The screw on the back is used to Calibrate the meterNOTE: When measured voltage is larger than 30V, the voltmeter will be damaged. Overall Dimension: 23mm x 15mm/0.9" x 0.59", Thickness: 10mm/0.39" Mounting Hole Center Distance: 28mmMeasure Voltage: DC 0~30V Working Voltage: DC 3V-30V Measurement Accuracy: 0.01(0.01 - 9.99V) / 0.1(10.0 - 30.0V); Display: Three 0.36" digital LED Tube Display Color: Blue Measurement rate: 300mS / times Operating Temperature: 14 ~ 149 °F(-10 ~ 65 °C) Reverse protection: Yes When measured voltage is below 10V: the voltmeter displays two decimal digits, for example, 5.32V When measured voltage is larger than 10V, the voltmeter displays one decimal digit, for example, 10.5V Wiring: Red wire: Power supply + Black wire: Power supply -, Measured Voltage - White wire: Measured Voltage + Package Includes: 5x DC 0-30V Voltmeter

Review: Work great. Accurate enough. I will be buying more to save my tools. - Great for B&D 20v converted tools with the "power wheels adapter". B&D Batteries or tools dont have a low voltage shutoff circuit. Relies on the motor requiring 15v. So if you use those batteries in other tools with adapters. You can drain them to a point of no recharge. This lets you monitor the voltage on tools to ensure you never drop past 16.5 volts. You are the low voltage shutoff circuit :D
Review: Nice little panel meters - Good looking blue LED display with a very small footprint. Good accuracy from 0 to 30V running off of a 5V supply. These do not measure negative voltages.

## Features

- This is Three-Wire Voltmeter. Three-Wire connection enable the Voltage Test Rang from 0.00 to 30V. (Two-wire meters cannot measure the voltage that is below 3V);
- Measurement Accuracy: 0.01(0.01 - 9.99V) / 0.1(10.0 - 30.0V); And the meter is CALIBRATABLE: The screw on the back is used to Calibrate the meter.
- BRIGHT & NICE Reading: Display: Three 0.36" digital LED Tube; Display Color: BLUE;
- Reverse Polarity Protection: The meter won't burn out if reverse polarity is applied, but the screen will display nothing
- NOTE: When measured voltage is larger than 30V, the voltmeter will be damaged.

### ⭐⭐⭐⭐⭐ Super
*by L***L on 17 May 2022*

Ça m'évite de sortir le voltmètre pour vérifié l'état des batteries. Un calibrage, par contre est nécessaire pour chaque voltmètre. J'aime bien.
