Panel Mount Current Meter


Panel Mount Current Meter


SKU: GAU-002


Do you need to keep tabs on the current draw of your project? This handy panel mount current meter can measure between 0.01 and 9.99A with an accuracy of +/-4%.

Connecting this current meter is a little more difficult than a standard Volt Gauge. The display ground wire is internally connected to the output current sensor wire so specific care needs to be taken when connecting these sensors. Doing this incorrectly will result in the sensor being shorted. So, to avoid damaging the sensor, there are two ways to connect this correctly:

Option 1: Using a separate power source for the gauge power

The easiest and safest way to use the meter is to have no electrical connection between the powering and sensing current. That is, connect something like a 9V battery to the thin power wires and you can put the current sensor in anywhere you want. As long as the circuits are totally separate this will work great.

Option 2: Low Side Sensing

If you need to power the gauge from the same power source you are monitoring current, you will need to use low side sensing. This means the you need to measure between the negative portion of the battery or power supply and the negative connection on device you are wishing to monitor. See attached image
