Measurement Operation(4)

C. DC Current Measurement (see figure 4)

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 4 measurement positions

on the rotary switch: 2mA, 20mA, 200mA and 20A.

To measure current, do the following:

1. Turn off power to the circuit. Discharge all high-

voltage capacitors.

2. Insert the red test lead into the mA or 20A terminal

and the black test lead into the COM terminal.

3. Set the rotary switch to an appropriate measurement

position in A range.

4. Break the current path to be tested. Connect the red

test lead to the more positive side of the break and

the black test lead to the more negative side of the

break.

5. Turn on power to the circuit.

The measured value shows on the display.
