5.5 Voltage Measurement
Rotate the rotary switch until the VOLTS test is
selected. The 9083P will start measuring voltage
immediately and use of the TEST key is not required.
The function keys do not perform any operations while
in Voltage mode.
For AC voltage measurements, the frequency of the
measured voltage is shown in the secondary display.
5.6 Earth Loop Impedance / Line Impedance
The 9083P will only allow the Earth Loop
Impedance test to be performed if the correct
voltages are detected between phase-neutral
(PN illuminated), phase-earth (PE illuminated)
and neutral-earth (NE
not
illuminated).
Rotate the rotary switch until the Zs test is selected.
Press the function key
F1
to select either the Earth
Loop Impedance test (
L-PE
) or the Line Impedance test
(
L-N
).

The secondary display will automatically show the
appropriate icon:
PFC
when
L-PE
is selected and
PSC
when
L-N
is selected.
Note: When the Zs switch position is selected, the
9083P will default to the last used setting,
even if it has been switched off.
To begin the test, press and release the TEST key.
Note: The 9083P will determine the fault voltage that
may appear on the protective conductor
during the test. If the fault voltage is greater
than 25V the 9083P will indicate >25V on the
LCD, but the user may proceed with the test. If
the fault voltage is great than 50V, this is
indicated on the LCD and the test is inhibited.
