Description
The reading of voltages is not complicated and fast with this mini voltmeter. The module is ideally suited to be permanently installed in a housing or other structure. But also the quick testing of batteries or accumulators is no problem thanks to the soldered cables. Simply 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 setups. If the measurement result must be very accurate, the voltmeter can be calibrated, via the potentiometer on the back. It is still important to know that the different display colors also bring different minimum voltages. This is because the different colored LEDs require different amounts of voltage to light up. The voltmeter with the red display can measure from 2.5-30V. The modules with the green and yellow display work from 2.6-30V and the one with the blue display works from 3-30V.
