5.9. DC CURRENT MEASUREMENT
CAUTION
Make sure that all the test leads are disconnected from the meter terminals
for current measurement
Fig. 31: Use of the instrument for DC current measurement
1. Select position
60A
,
600A
o
1000A
2. Press key
MODE/VFD
to select measurement “A “
3. Long press key
HOLD/REL
to perform the zeroing of residual magnetization current
(see § 4.3.5)
4. Put the conductor to be tested inside to the center of clamp jaw (see Fig. 31) in order to
perform accurated measurements in the direction from positive pole “+” (see Fig. 1 –
part 2) to the negative pole “-“ (see Fig. 2 – part 1). Consider the notches on jaws as
reference (see Fig. 3)
5. The display shows the value of DC current.
6. If the display shows the message
“
OL
”
, the maximum measurable value has been
reached.
7. When symbol
“
-
”
appears on the instrument's display, it means that current has the
opposite direction with respect to the connection in Fig. 31
8. To use the HOLD function, see § 4.2
9. To use the internal functions, see § 4.3.3
10. To save the measured result, see § 4.3.4
