Featuring reverse polarity protection and adjustable voltage resistance, this mini digital voltmeter is perfect for both professional and DIY applications. With a user-friendly three-wire connection that can be adapted to two wires, it ensures safety and precision in every use. ## Description Features: High precision Reverse connection protection. The decimal point is automatically moved ADJUSTABLE VOLTAGE RESISTANCE Turn clockwise to lower voltage, it can work directly into 5V, 9V, 12V, 24V. Three-wire connection, but it can also change three wires to 2-wire connection. Technical parameters: 2-wire working voltage: 4.0~40V (with reverse connection protection) 2-wire detection voltage: 0.0~40V 3-wire working voltage: 4.0~40V (with reverse connection protection) 3-core detection voltage: 0.0~100V Working current: 20 mA. Detection rate: ≥200mS/times Mounting hole: 23 x 10 mm. Measuring Accuracy: 3% The minimum working voltage: +4 V. The maximum operating voltage: +30 V. Operating temperature: -10 to +65 °C. Working humidity: 10~80% (no condensation) Dimensions: 22.5 x 10 x 7 mm (L x W x H). Measurement rate: ≥ 200 mS/times. Accuracy: 3 Permil; (+/- 1 word) Operating temperature: -10 ~ +65 °C. Working humidity: 10 ~ 80%. Working Pressure: 80~106KPA Color:This package includes 4 colors three line mini digital dc voltmeter. Box contents: 4 x 0-100V 3 conductor DC digital voltmeter red yellow green blue Review: Expensive But work - these look good, as described, checked and had to adjust 2 of them as they were slightly out on there reading. Used one for a diode tester to read the voltage drop across them. Plus checking they are not shorted. Review: cheap but is it cheerful? - Quick efficient, well packaged delivery. However one unit dead on arrival another had a disconnected solder joint on the ground line but once re-soldered it functioned as advertised, I would only give 2 stars for quality and the lack of any detailed data sheet is not helpful especially when switching 3 to 2 line and using voltage/resistor trimmer. I also would have severe doubts about using these units for anything above 12Volts ## Features - Detection voltage: 0-100V. - High precision, reverse connection protection, the decimal point is automatically shifted - Adjustable voltage resistance: turn clockwise to lower voltage, can be directly operated in 5V, 9V, 12V, 24V. - Dre. i-wire conneting, but it can also change three lines to 2-wire connection - Note: the three-core voltage range is 0-100V, which can also be used as a second line, but the voltage should be within 40V. ## Images ![4pcs DC Digital Voltmeter 0.28 Inch Three-Line DC 0-100V Mini Digital Voltmeter Gauge Tester LED Display Reverse Polarity Protection and Accurate Pressure Measurement 4Colours - Image 1](https://m.media-amazon.com/images/I/71lOnXDkA9L.jpg) ![4pcs DC Digital Voltmeter 0.28 Inch Three-Line DC 0-100V Mini Digital Voltmeter Gauge Tester LED Display Reverse Polarity Protection and Accurate Pressure Measurement 4Colours - Image 2](https://m.media-amazon.com/images/I/61dq0pIX8mL.jpg) ![4pcs DC Digital Voltmeter 0.28 Inch Three-Line DC 0-100V Mini Digital Voltmeter Gauge Tester LED Display Reverse Polarity Protection and Accurate Pressure Measurement 4Colours - Image 3](https://m.media-amazon.com/images/I/71eUcenXaWL.jpg) ![4pcs DC Digital Voltmeter 0.28 Inch Three-Line DC 0-100V Mini Digital Voltmeter Gauge Tester LED Display Reverse Polarity Protection and Accurate Pressure Measurement 4Colours - Image 4](https://m.media-amazon.com/images/I/71fVpjT7uAL.jpg) ![4pcs DC Digital Voltmeter 0.28 Inch Three-Line DC 0-100V Mini Digital Voltmeter Gauge Tester LED Display Reverse Polarity Protection and Accurate Pressure Measurement 4Colours - Image 5](https://m.media-amazon.com/images/I/61HlCGtbnAL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐ Expensive But work *by P***R on 12 February 2023* these look good, as described, checked and had to adjust 2 of them as they were slightly out on there reading.
