OPTIONS
37
Arc-Sen= X
Use the Up/Down Arrow keys to select the arc sensitivity level. The arc sensitivity
level may be set between the values of 1 and 9, 1 being the least sensitive, 9 being
the most sensitive. To deactivate the Arc Detection set the arc sensitivity to 0.
Press the EXIT key to exit to the test mode or toggle to another setting using the
SET key.
OPERATION PROCEDURE
If there is an arcing condition over the Arc sensitivity limit, the red indicator light
will illuminate on the reset switch and an alarm sound. The display will show:
Arc MX XXX.Xs
X.XXKVAC OFL mA
05 Floating Return
This option separates the Return from the Earth ground. With this option, the
Return lead of instrument is not connected directly to earth ground; this eliminates
monitoring stray leakage currents that flow to earth ground. The metering circuit
monitors only leakage current flowing from the DUT, through the Return test lead
to the Return connector. Therefore, it is crucial that the DUT does not make
direct contact with earth ground or the metering circuit and leakage fail detectors
will be Bypassed.
06 Remote Memory Select
This option enables remote operation of three pre-programmed test setups
(Memories 1-3) through the rear panel input connector. This gives the user the
capability to quickly change parameters and initiate a test remotely. The three
memory setups can be accessed by connecting pins 7, 8 and 9 in different
combinations.
ACTIVATING MEMORY PROGRAM FUNCTIONS THROUGH
THE REMOTE CONNECTOR SELECTS THE PROGRAM AND
STARTS THE TEST THAT IS PREPROGRAMMED INTO THAT
MEMORY IMMEDIATELY.
MEMORY ONE – Momentarily connecting pin 7 to pin 8 immediately begins the
test program that is stored in memory one.
MEMORY TWO – Momentarily connecting pin 7 to pin 9 immediately begins the
test program that is stored in memory two.
