Power Line Voltage; Touch (Contact) Voltage - Fluke Calibration 5322A Operator's Manual

The Product shows the following for an RCD trip time calibration:
•
DUT test signal polarity is indicated with one of the following icons:

Similar to the Trip current function, the current reading is displayed in red, and
noted as a real (actual) tripping current or recalculated to a nominal line voltage.
Nominal line voltage is selectable under Setup>RCD>Trip I Nom Line V
Correction. The nature of the tripping current is shown after the current reading,
either Real or the selected nominal line voltage.
If the signal cannot be recognized, then Not recognized is displayed. When the
trip time is set to <20 ms, only positive and negative polarity are detected. If a
negative dc test current is detected, a NEG symbol is displayed. If a positive dc
test current is detected, a POS symbol is displayed. Phase is not displayed for dc
sensitive signals.

Power line/Touch voltage

Power Line Voltage

The Product measures the power line voltage as a first step in the tripping
procedure. This voltage is measured after the output terminals are switched on.

Touch (contact) Voltage

Touch voltage is the voltage difference between N and PE potentials. DUTs can
usually measure this voltage and display it as a measured value or detect
crossing over the safe voltage level (25 V to 50 V typical) with an indication of
this event. Touch voltage generated by the Product depends on selected series
resistance and setup nominal trip current. It is scanned and displayed in this field.
See Figure 16.
