C. DC CURRENT TESTING (SEE FIGURE 5)
(figure 5)
Warning!
Before connecting the Meter in serial to the tested in-circuit, disconnect in-circuit power.
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 otherwise it
will burn the fuse or damage to the Meter.
The current ranges are: 200mA and 10A.
To measure DC current, connect the Meter as follows:
1. Insert the red test lead into the
terminal and the black test lead into the
COM
terminal.
2. Set the rotary switch to an appropriate measurement position in
.
3. Connect the test leads in serial to the object being measured.
The measured value shows on the display.
Note
- If the value of current to be measured is unknown, use the maximum measurement position
(10A) and
10A
terminal, and reduce the range step by step until a satisfactory reading is obtained.
- When DC current measurement has been completed, disconnect the connection between the
testing leads and the circuit under test.
- When measuring 5A~10A: for continuous measurement ≤10 seconds and interval time
between 2 measurement greater than 15 minutes.
