4.3.7. DC Current measurement (only HT9015)
CAUTION
Make sure that all the test leads are disconnected from the meter terminals
for current measurement.
Fig. 9: Taking DC current measurements
1. Rotate the switch on 60A
or 600A position
2. Pushing MODE key and select the kind of measure “DC”
3. Pushing PK/REL key to perform the zeroing of residual magnetization current
CAUTION
The zeroing operation of residual magnetization current is essential to obtain
accurate results
4. Put the conductor to be tested inside to the center of clamp jaw to perform accurated
measurements. Consider the notches on jaws as reference (see Fig. 2). The reading
will be displayed
5. On DC current measurement the “-“ symbol at display means that the meter is
connected in the opposite side compared with current direction (see Fig. 9)
6. When “O.L.” symbol is displayed, the result exceeds the maximum value that the
instrument is capable of measuring. Select an higher range
7. For HOLD, MAX/MIN and REL features please refer to § 4.2
