6 EXTERNAL CURRENT MEASUREMENT
3] Select "External" for "Current measure-
ment".
4] Press the numeric field to set the "Ratio" for
the current clamp to be used
5] Press
6] Activate the warning and stop limit func-
tions.
7] Connect the DC clamp-on current probe to
input I EXT ≤ 1 V. Best results are obtained if
the cables running from the DC clamp-on
current probe are twisted.
Note If the DC clamp-on current probe has an
adapter for using external power supply. Use
the power supply from TORKEL (DC Out) con-
nector, that gives 9 V.
Important
The DC clamp-on current probe must
always be applied in such a way that cur-
rent through TORKEL is included in the
measurement.
8] Apply the DC clamp-on current probe to the
conductor.
9] Turn on the power switch on the DC clamp-
on current probe.
10] Make the setup for preferred test mode.
Troubleshooting
1] Check that the DC clamp-on current probe is
properly connected to TORKEL.
2] Check that the DC clamp-on current probe is
switched on.
3] Check that the DC clamp-on current probe
has fresh batteries.
4] Check the following settings in “TEST SET-
TINGS”, "Settings":
• “I measurement” must be set to “External”.
• The mV/A ratio must match the ratio that
appears on the DC clamp-on current probe
itself.
6.3 TORKEL used together
with TXL Extra Load
A current shunt can also be used, but this requires opening
the current path and connecting the shunt in series.
Multiple units used together
One TORKEL control
The first TORKEL regulate the TXLs.
1] Apply the clamp-on-probes as illustrated
above.
2] Set the desired total current on TORKEL 1
.
