4.4.4. AC Current and Frequency measurement
CAUTION
The maximum input AC current is 1A. Do not measure currents exceeding
the limits given in this manual. Exceeding current limits could result in
electrical shocks to the user and damage to the instrument.
Fig. 5: Use of the instrument for AC current measurement
1. Cut off power supply from the circuit to be measured.
2. Select position
A
or
mA
(for measuring currents <50mA).
3. Press the
MODE
key for manually selecting “AC” or “AC+DC” measurement (see
§ 4.3.3) or press the
HFR
key for “HFR” measurement (see § 4.3.4).
4. Insert the red cable into input lead
mA
or
A
and the black cable into input lead
COM
5. Connect the red lead and the black lead in series to the circuit whose current you want
to measure (see Fig. 5)
6. Supply the circuit to be measured. The display shows the value of current.
7. If the display shows the message “
OL
”, the maximum measurable value has been
reached.
8. Press the
Hz
key to display the frequency measure of AC current. The symbol “Hz” is
shown on the display.
9. For using the HOLD function see § 4.2.1, for measuring MAX/MIN/AVG values see
§ 4.3.1, for relative measurement see § 4.2.1 and for saving the result see § 4.3.5.
