The Hypot III comes with all of the memories and steps loaded with the AC withstand default
parameters. The initial test loaded for use is Memory 1, Step 1. If this test is unacceptable for
your DUT then refer to the section 4.3 Setting Up a Test, for instructions on how to program
tests into the instrument.
If these parameters are acceptable then connect an appropriate set of test leads to the device
under test (DUT) or test fixture. Connect the return lead (Black) to the DUT or test fixture
followed by the high voltage output lead (Red). Make sure the safety ground of this instrument
is connected to a known good ground.
Refer to section 4.1.3 System Parameters, Smart GFI, for an explanation of DUT grounding
configurations.
DO NOT TOUCH THE DEVICE UNDER TEST ONCE THE TEST HAS
BEEN STARTED.
Remote Interlock
Hypot III is equipped with a featured referred to as “Remote Interlock”. Remote Interlock is a
feature that utilizes a set of closed contacts to enable the instruments output. In other words, if
the Interlock contacts open, the output of the instrument will be disabled. Remote Interlock
could also be referred to as a remote system lockout, utilizing “Fail When Open” logic. If the
Interlock contacts are open and the Test button is pushed, a pop-up message will be displayed
on the screen for two seconds. The message will appear as follows:
If the Interlock contacts are opened during a test, the pop-up message will be displayed and the
test will abort. The hardware has been configured to provide the interlock connections on pins
4 and 5 of the Remote Interface, Signal Input port. The instrument can still be used without the
external interlock device as long as the Interlock Connector (38075 provided with unit) is
plugged into the Remote Interface, Signal Input port. If there is nothing connected to 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 (in this case Memory 1, Step 1) .
If the DUT passes the test, you will hear a short audible beep. If a failure occurs you will hear
a long audible alarm and the red failure indicator will light up. If a failure occurs during the
test, a continuous alarm will sound and the red indicator light in the Reset button will
illuminate.
WARNING
Interlock is Open
