Figure 48 shows the winding resistance main settings.
To select the H-Side current that injects into the primary winding side
To select the X-Side current that injects into the non-primary winding side
The stability condition is a reference for the device to decide if the resistance value during
a measurement is considered stable or not. For example, 0.1%/5s means that if the
resistance fluctuations keep less than 0.1% of the average value continuously for more
than 5 seconds, it will be considered stable
The maximum acceptable deviation value. Please see chapter 4.2.3 for more information
INFO:
Do not select currents more than 10% of the test object nominal
current for each side. Otherwise, current will increase the temperature
and hence resistance of the winding.
