SAFETY
Do not perform Hipot tests in a combustible atmosphere or in any area where
combustible materials are present.
TEST OPERATOR
Qualifications
This instrument generates voltages and currents which can cause harmful or fatal
electric shock and must only be operated by a skilled worker trained in its use.
The operator should understand the electrical fundamentals of voltage, current, and
resistance.
Safety Procedures
Operators should be thoroughly trained to follow these and all other applicable safety
rules and procedures before they begin a test. Defeating any safety system should be
treated as a serious offense and should result in severe penalties, such as removal from
the Hipot testing job. Allowing unauthorized personnel in the area during a test should
also be dealt with as a serious offense.
Dress
Operators should not wear jewelry which could accidentally complete a circuit.
Medical Restrictions
This instrument should not be operated by personnel with heart ailments or devices such
as pacemakers.
TEST PROCEDURES
NEVER PERFORM A HIPOT TEST ON ENERGIZED
CIRCUITRY OR EQUIPMENT!
If the instrument has an external safety-ground connection, be sure that this is connected.
Then connect the return lead first for any test regardless of whether the item under test is
a sample of insulating material tested with electrodes, a component tested with the high
voltage test lead, or a cord-connected device with a two or three-prong plug.
Plug in the high voltage test lead only when it is being used. Handle its clip only by the
red insulator sleeve---never touch the clip directly. Be certain that the operator has
control over any remote test switches connected to the Hipot. Double-check the return
and high voltage connections to be certain that they are proper and secure.
NEVER TOUCH THE ITEM UNDER TEST OR
ANYTHING CONNECTED TO IT WHILE HIGH
VOLTAGE IS PRESENT DURING THE HIPOT TEST.
DO NOT TOUCH THE FRONT PANEL WHEN TESTING
OR AFTER A MALFUNCTION HAS OCCURRED.
