the pre-loaded program step and the parameters stored with in it. If this test is unacceptable
for your DUT then refer to the section
4.5 Setting Up a Test
, for instructions on how to
program tests into the instrument.
If these test file parameters are acceptable then connect an appropriate set of test leads to the
device under test (DUT) or test fixture. Make sure the safety ground of this instrument is
connected to a known good ground.
Refer to section

Remote Interlock
7630 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 and 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 (1505
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 from the selected default file.
