Voltage Polarity
The Voltage Polarity settings allow for toggling the polarity without it being
necessary to change the wiring when voltage probes are connected in wrong
polarity due to a wiring mistake.
Current Probes Info
The Current Probes Info section provides the status and configuration for the
current probe detection mechanism. When it is successfully detected, the
probe type is displayed on the Info section. If no probe is con-
nected/detected, the Info shows a No probe detected string.
Configuration options are directly dependent on the probe type, for example,
the mini clamp 1A/1V (refer to page 11 for specifications) is normally
used to measure a secondary current of a current transformer (CT). In that
case, the CT should be defined as Primary/Secondary values. On flexible
probe types, these settings are not available.
Nominal (A) value plays an important role for the PQZip recording func-
tionality (refer to PQZip on page 111). In the event that the probe is
identified, the value is automatically set to probe default.
