JOY-it COM-VM330 Voltage with 3-Digit LED Display
GENERAL INFORMATION
Dear customer,
Thank you for purchasing our product. In the following, we will show you which
things should be noted during the use. Should you encounter any unexpected
problems, do not hesitate to contact us.
USAGE
This voltmeter can measure DC voltages from 3 V to 30 V without requiring an additional power supply for the meter. To measure a voltage, connect the positive end of the voltage you want to measure to the positive terminal of the voltmeter (red wire) and the negative end of the voltage source to the negative terminal of the voltmeter (black wire).
| V | + | – |
|---|---|---|
| Not connected | Measuring voltage + |
( 3 V – 30 V)
| Measuring voltage –
You can also measure voltages below 3 V with this voltmeter, but for this you have to supply power to the display regardless of the measuring voltage. This requires soldering, because you have to remove a solder bridge on the back of the unit and solder more wires to the board.
Now you have a new pin assignment on the measuring device. Please note that two ground connections must be connected to the negative terminal of the measuring device (black cable) (one for the measuring voltage and one for the supply voltage).
