- Hall Effect Current Sensor (GS-AMPS)
How can I monitor two different currents on one monitor?
For monitoring 2 batteries, if I buy 2 GS-AMPS adaptors and use another switch to select the battery, which wires (of the 3) would I need to switch, and would I need a make-before-break or other type of switch to protect the gauge internals?
A switch may be used to choose between the two yellow wires (the others should be permanently connected as they are power and ground). During programming, the connected GS-AMPS sensor is calibrated (‘zeroed’) so the other sensor may show a slight error.
Why does my current display as negative?
The wire has been passed through the loop of the current shunt (GS-AMPS) in the wrong direction.
Can you read 2 sets of Current (Amps) on a single gauge?
I.e. See the current in battery 2 from battery 1?
No, there is only provision for one Hall Effect (current) sensor. Two G52-VA gauges could be used, each with a GS-AMPS Hall effect sensor.
The current (Amps) going into the battery so why is there a negative displayed?
Current flow can be in either direction, that is, current going into the battery (+) or current being taken out of the battery (-). This will be the same as you would see on an ammeter/multimeter.
