الوصف
This is a small volt and current meter that you can connect to your power source and device/load to keep an eye on the status of your device.
Notice
- The voltage between the thin red and thin black lines must be within DC 4.5-30V
- The ammeter can only be connected to the negative of the device under test
- 10A below ammeter (include 10A), built-in shunt, does not require an external shunt
- When the black thin line is vacant, it is better to use insulating tape around the exposed part of the wire, to prevent short circuits
- If just being used as a voltmeter, it is recommended that the yellow line and the black line were connected together, to prevent the ammeter digital flashing
