5. OPERATING INSTRUCTIONS
5.1. Instrument Connections
Before the operation of this instrument, make sure that all Test Parameters have been
set properly according to the Test Parameters Setup Procedures. Also, check the
system setting of Remote Control, LCD Contrast, the Alarm Volume, and Fail Stop.
Be sure to connect the appropriate test leads to the device under test (DUT) or test
fixture. Be sure to connect the safety ground (on the rear panel) to a suitable known
good ground before energizing this instrument. Then connect the return lead first to
the test fixture or the DUT followed by the high voltage lead.
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.
DO NOT TOUCH THE DEVICE UNDER TEST, HIGH VOLTAGE
TEST LEAD, ALLIGATOR CLIP, OR CLIP INSULATOR ONCE
THE TEST HAS BEEN STARTED.
DO NOT TOUCH THE FRONT PANEL WHEN TESTING OR
AFTER A MALFUNCTION HAS OCCURRED.
This instrument is supplied with a high voltage test lead terminated with an alligator
clip. This clip is designed to allow firm connection to the DUT without the need for an
operator to hold a probe or lead in place during the test. This clip and insulator will
carry the voltage and current of this tester but they are not intended to be held by the
operator during the test while the high voltage is energized. Please insure that you do
not make contact with the alligator clip or the clip insulator while high voltage is
energized.
Interlock Connector
HypotMAX is equipped with a Remote Interlock feature. Remote Interlock utilizes a
set of closed contacts to enable the instrument’
s output. If the Remote Interlock
contacts are open the output of the instrument will be disabled. To disable the
Remote Interlock feature connect the Interlock Key into the Signal Input port located
on the back of the tester.
