## 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: 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.
Review: They work accurately enough to give you a point of reference. Not expensive, so not top tier. Example: Vehicle is charging at 14.4v@idle as verified on multimeter at display connection, adjust pot to calibrate this display to match meter, then turn off car to see 12.4 on meter and 12.7 on this display.... As stated, ideally used as a point of reference (you are above or below your target range). The deviation will spread as the range gets wider, but it's perfect for a voltmeter in the dash or on an amp. Just a monitoring tool, not a diagnostic tool.

## 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.

*by E***K on 14 June 2019*

They all seem a accurate, and only had to adjust one of them by 0.1V based on the reading from my Fluke meter. Bright display, easy to read. Like the Three wire set up for reading voltage of same device or separate one. Dislikes... With the lack of a bezel you need a CNC machine to cut out a accurate hole to mount them and still look nice... See picture.... The wires come out the top of the board... See other picture... So when you mount it thru the plate. You need a couple washers to space it so it rests flat. If the wires were soldered to the other side of the board, this would not be an issue. Still would recommend
