OMICRON 151
Using the Quick Test feature
10.5 Polarity check
This measurement type is exclusively intended for polarity checks using the
CPOL2 polarity checker as described below. Do not use this mode for any
other measurements!
Note: The Polarity Check measurement type requires the CPOL2 polarity checker
from OMICRON.
Polarity Check is a predefined measurement type, intended especially for checking
a series of test points (e.g., the connecting terminals of the burden wiring) for
correct polarity. For this purpose, CT Analyzer injects a signal with a special
waveform similar to a saw-tooth signal with a different steepness for the rising and
the falling slope. The CPOL2 polarity checker from OMICRON checks the polarity of the injected signal
and provides a clear indication whether the polarity is OK or not.
Checking the polarity using the Polarity Check measurement type is much faster than conventional
methods and can easily be performed by a single person.
To select the Polarity Check measurement type, use the cursor key to move the cursor to the
Measurement Type field in the CT-Quick card and then press the Polarity Check soft key.
