Test Voltage (U
set
= 1000 V)
Test voltage for the inter-turn short circuit measurement is perma-
nently set to 1000 V and cannot be changed.
Connection and Contacting
➭ Make sure that the device under test is voltage-free.
Note
In combination with the COIL ADAPTER XTRA, interfer-
ence voltage can only be detected under certain condi-
tions.
➭ Connect the
COIL ADAPTER XTRA
to the S+ and sockets at
the multimeter via the contact protected plug.
➭ Connect the three measurement cables to the sockets la-
beled U, V and W at the
COIL ADAPTER XTRA
. In doing so,
make sure that the color coding included on the measurement
cables and the sockets matches up.
➭ If possible, contact the inductive device under test with op-
tional alligator clips plugged onto the test probes. Simultane-
ously contact coil terminals U, V and W, or L1, L2 and L3.
Caution: High-Voltage!
Do not touch the conductive ends of the test probes as long as
measurement is active and the Stop softkey is displayed.
A voltage of up to 1200 V is present at the multimeter’s two
enabled output sockets, and as a pulsed voltage at the output
sockets of the COIL ADAPTER XTRA (identified with U, V, W).
Multimeter: You may otherwise be exposed to a current of
2.5 mA (limited in the measuring instrument), and although
this is not life endangering, the resulting electrical shock is
quite discernible.
COIL ADAPTER XTRA
: Power pulse currents of up to 600 A
can flow from the output sockets.
The device under test can become charged: wait until voltage at
the device under test has been discharged after each mea-
surement. The rotary switch may not be turned in order to
start the next measurement until after the “Select next
switch position at COIL Adapter” prompt appears, which is
displayed subsequent to the “Discharging – please wait”
message. Touching the device under test may otherwise be
life endangering!
Caution: High-Voltage!
In the case of inter-turn short circuit measurements at
transformers, very dangerous high-voltage may occur at the
output side depending on the transformation ratio.
Caution: High-Voltage!
For safety reasons, all three motor terminals must always be
connected to the adapter when measurements are con-
ducted at 3-phase motors. Dangerous voltage may be
present at unconnected motor terminals.
Selecting the Inductance Range
Note
The High or Low inductance range is selected with the
rocker switch at the COIL ADAPTER XTRA:
High: 5 mH to 5 H (0.16 kVA to 160 kVA)
Low: 10 μH to 50 mH (15 kVA to 80 MVA)
