4.3.9. AC Current measurement

Maximum input AC current is 10A (input 10A) or 600mA (input mAA). Do
not measure currents exceeding the limits given in this manual. Exceeding
voltage limits could result in electrical shocks to the user and damage to the
instrument.
Fig. 10: Use of the instrument for AC current measurement
1. Cut off power supply from the circuit to be measured.
2. Select positions A
3. Press the MODE key to select
4. Insert the red cable into input terminal 10A or into input terminal mAA and the black
cable into input terminal COM.
5. Connect the red lead and the black lead in series to the circuit whose current you want
to measure (see Fig. 10).
6. Supply the circuit to be measured. The display shows the value of current.
7. If the display shows the message
reached.
8. Press the Hz%/REL key to select measurements
values of frequency and duty cycle of input voltage. The bargraph is not active in these
functions.
9. To use the HOLD, RANGE, MAX MIN, PEAK, REL and HIRES functions, see § 4.2
