3 Digital Mini Blue 100mV/100mA Meter
New version, faster response to current change!
This meter is specially designed for a 100mA measurement (100mA full scale). It's ready to use with a CO2 laser power supply for a current indicator. Just connect it in series with the negative from the power supply to the tube and that will show real time current. Specifications
Power: 5V DC +/- 0.2V
Accuracy: +/- 0.5% Type: LED (blue) Range: 0-99.9mA Resolution: 0.1mA Dimensions: 45mm x 26.5mm x 20mm Mount hole: 42mm x 25.5mm
No shunt is needed and it is ready to use.
Please note: The meter is powered by 5V DC and you need a DC-DC isolated power module if you're trying power it up using the same DC source with other devices.
Do NOT reply on the color of the wire for connection because it may change. Always looks for marking on the wire hardness: +5V, -5V, -IN, +IN
+5V, -5V (5V power source to power up the meter)-IN, +IN : +IN connects to negative of the laser tube, -IN connects to the negative side of the power supply.
