Item Description
E Impedance & RCD Terminals XWWarning
Electric shock hazard. Lethal voltages are either applied
to or supplied from these terminals when the Calibrator
is operating. Ensure the Calibrator and UUT is in standby
mode before connecting or removing leads to these
terminals. AC Line Voltage is supplied from these
terminals when the Calibrator is performing a Loop
Impedance, Line Impedance or RCD calibration.
Provides connection points for the Loop and Line impedance
testing as well as RCD testing.
F METER Terminals Provides connection points for meter measurements. The V
terminal is for ac and dc voltages. The A terminal is for ac
and dc currents. The COM terminal is the return for all meter
measurements.
G Display Panel The display panel is a 16-color active LCD display used to
display Calibrator status, output levels, measured voltage,
resistance and current and active terminals. In addition, the
bottom line of the display indicates the function of the five
softkeys just below the display panel. See the Display Panel
section below for more details on the displayed information.
H Softkeys The functions of the five unlabeled softkeys are identified by
labels on the Control Display directly above each key. The
functions change during operation so that many different
functions are accessible through these keys. A group of
softkey labels is called a menu. A group of interconnected
menus is called a menu tree.
I Output Function Keys Selects the output function. The output functions are:
V AC/DC Voltage Calibration (5320A/VLC only)
L Low Resistance
N Leakage Current
H High Resistance
J Impedance/RCD Keys Selects the impedance and RCD functions. These functions
are:
Z Loop/Line Impedance
G Ground Bond Resistance
R RCD Time & Trip current
