Measurement Operation(4)
C. DC Current Measurement (see figure 5)
Warning
Never attempt an in-circuit current measurement
where the open circuit voltage between terminals
and ground is greater than 60V DC or 30V rms.
If the fuse burns out during measurement, the Meter
may be damaged or the operator himself may be hurt.
Use proper terminals, function, and range for the
measurement. When the testing leads are connected
to the current terminals, do not parallel them across
any circuit.
The DC current measurement has 3 measurement
positions on the rotary switch: 20mA, 200mA and 20A.
To measure current, do the following:
1. Turn off power to the circuit. Discharge all high-
voltage capacitors.
