The maximum current measurement range is 600A.
Set the Function Switch to the V position, press FUNC to select AC or DC Voltage, insert test leads into COM and V/Q jacks, and connect them in parallel with the circuit.
Use the ZERO procedure to zero the meter before taking DCA measurements for best results.
