8.3.1.1 Preparing for Measurement
Note
Inter-turn short circuit measurements may only be con-
ducted on voltage-free coils.
➭ Set the rotary switch to “
RISO
” or “
COIL
”.
➭ Repeatedly press the Func softkey until the measurement view 
for COIL appears at the display.
➭ Select the motor or coil type to be tested under the measure-
ment type parameter in “Setup for present measurement” (see 
below).
Selecting the Type of Measurement
 > Momentary Measurement Setup > Parameter   
Measurement Type 
 Coil / 1-Ph. Motor / 3-Ph. Motor   
 3 x > Measurement View
1-Ph. Motor: AC motor (L1)
3-Ph. Motor: 3-Phase motor (U-V, U-W, V-W)
Coil Motor with up to 15 coils (L1 - L15)
➭ Select polarity: unipolar or bipolar (see below).
