8.3.2.3 Starting a New Measurement Series / Measuring Routine
In order to start a new measurement series, you can:
– Delete the respectively recorded measurement for each coil
as described under “Measured Value Displays”, or
– Reselect the COIL measuring function with the help of the Func
softkey (or by turning the rotary switch)
– Start a new measurement series by pressing the Restart soft-
key
8.3.2.4 Stopping/Ending Measurement and Discharging
You can stop an active measurement (of a coil) at any time, as
long as the measurement results have not yet been displayed.
➭ Press the Stop softkey.
After measurement has been ended, any remain-
ing residual voltage (Uext) is displayed (message:
“Discharging – please wait”), which may result
from cable capacitance. The instrument’s internal
1M resistor causes rapid discharging.
Contact to the motor coils must be retained to this end.
Do not disconnect the DUT until voltage has fallen
below 25 V, i.e. until after the “Discharging – please wait” message has
been cleared from the display.
➭ Press the Start softkey in order to restart the measurement.
8.3.2.5 Interrupting the Measurement Series / Measuring Routine
➭ The measurement series can be interrupted by setting the ro-
tary switch to the “0” position.
➭ In order to resume the measurement series, set the rotary
switch to the desired coil (e.g. V-W) and press the Start soft-
key once again.
8.3.2.6 Saving the Measurement Series
The values obtained during the measurement series can be saved
to the instrument’s internal memory by pressing the STORE key
after the measurement series has been completed.
