AZDelivery Module Mini Digital Voltmeter Panel 2,5V-30V DC 0.28 Inch with 7 Segment Display Voltmeter 2,5V-30V DC The Mini Voltmeter allows the reading of the voltages in a simple and fast way. Due to its characteristics, the Module is perfect to be installed in a house or another structure for a long time. Since it has Welded Cables the quick test of batteries or accumulators can be developed. In addition to its versatility, it has an easy connection. Just connect the black cable to the negative pole of the battery and the red cable to the positive pole of the battery. The reverse polarity protection makes it safer to use, especially for temporary installations. In case the reading is very accurate, the voltmeter can be calibrated, through the potentiometer on the back. The different colours displayed on the screen have different minimum voltages. This is because different coloured LEDs require different amounts of voltage to illuminate. So, each colour reflects a different range, the voltmeter with the red screen can measure from 2.5 to 30 V modules with the green screen and the yellow screen work from 2.6-30V and the blue screen from 3-30V. ✔️ Measuring range: 2.5V/2.6V/3.0-30V. ✔️ Operating voltage: Minimum 3V. ✔️ Screen: 0.28″ LED. ✔️ Screen colours: Red, Green, Yellow, Blue. ✔️ Measurement accuracy: +- 5%. ✔️ Cable length: approx. 20 cm. ✔️ Dimensions: 31x14x10mm. ✔️ Weight: 4gome to the AZDelivery family! Here you will find high quality products for your projects with Raspberry Pi. We are pleased to offer you a series of application examples, complete installation guides, E-Books, libraries and personalized assistance. AZDelivery: Your Microelectronics Expert!
