Description
AZDelivery 0.28 inch mini digital voltmeter with 7 segment display 2.5 V - 30 V voltage meter module
Reading voltages is easy and fast with this mini voltage meter.
The module is ideal for permanently installed in a housing or other construction. But the quick testing of batteries or batteries is also no problem thanks to the soldered cable.
Simply connect the black cable to the negative pole of the battery and the red cable to the positive pole of the battery. Reverse polarity protection ensures safe use, especially in temporary structures.
If the measurement result needs to be very accurate, the voltmeter can be calibrated via the potentiometer on the back. It is still important to know that the different display colours also have different minimum voltages. This is because the different coloured LEDs require different amounts of voltage to light up.
The voltage meter with the red display can measure from 2.5 - 30 V. The modules with the green and yellow display work from 2.6-30 V and the blue display works from 3-30 V.
