How To Read Amps On A Clamp Meter. Make sure the circuit is turned on. To explain this in more detail if you are testing for voltage set the clamp meter to a voltage setting.
In order to read amperage of DC you need a meter thats inline with the current flow between the source battery andor alternator and the load. How to make a DC Clamp meter. An ordinary clamp meter measures alternating current.
That should give a true reading in amps.
Most ammeters use a shunt reading a set percentage of load for safety concerns. Keep the lead where it is and switch to the 10A range. Select the AC current or DC current function using the dial. That should give a true reading in amps.
