4.3.6. DC Current measurement
CAUTION
Maximum input DC current is 10A (input 10A) or 400mA (input
VHz%mACAP ). 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. 8: Use of the instrument for DC current measurement
1. Cut off power supply from the circuit to be measured.
2. Select positions
“A ”, “mA ” or “10A ”
3. Press the MODE/ key to select “DC” measurement.
4. Insert the red cable into input terminal 10A or into input terminal VHz%mACAP
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, respecting polarity and current direction (see Fig. 8).
6. Supply the circuit to be measured. The display shows the value of current.
7. If the display shows the message "O.L", the maximum measurable value has been
reached.
8. When symbol "-" appears on the instrument's display, it means that current has the
opposite direction with respect to the connection in Fig. 8.
9. To use the HOLD, RANGE and MAX MIN functions, see § 4.2
