the Remote Interface, Signal Input port to provide a connection to the interlock, the instrument
will not perform tests.
Please check your connections to be sure they are making good contact. Clear the area of any
debris that may create a hazardous situation and ask any unnecessary personnel to leave the
area. To initiate the test, press the GREEN TEST button on the front panel. This is a
momentary button and does not need to be held in the pressed position during the test. The
instrument will then initiate the test presently loaded from the selected memory.
If the DUT passes the step, you will hear a short audible beep. If a failure occurs during a step,
you will hear a long audible alarm and the red failure indicator will light up. If the fail stop is set
to OFF and the Connect is set to ON, then the next step in the sequence will begin. If a failure
occurs during any step of the test sequence, a continuous alarm will sound and the red indicator
light in the Reset button will illuminate at the end of the last step.
To stop the alarm you must press the illuminated RED button marked RESET. This will silence
the alarm. Pressing the RESET again will clear the red fail light, and reset the instrument for the
next test. The RESET button may also be used to quickly ABORT a test and cut off the power
to the DUT.
When a test is being performed, a red lightning bolt indicator located in the lower right side of
the front panel will illuminate and flash until the test is finished. If the DUT passed the entire
test sequence, you will hear a brief beep indicating the DUT passed and that the tests are
complete.
