Section 1
An Introduction to Dielectric Withstand Testing with the HT-2000P
The continuity test/dielectric withstand test is a production line test which is recognized
by safety agencies worldwide as a valid criterion of safe assembly of end-use equipment. The
test ensures that the primary circuit power and ground conductors were properly wired and
connected for safe operation. It also applies a high-voltage potential between power and ground
conductors to make sure that no unintentional leakage or arcing paths exist between power and
ground. The test consists of a ground continuity check, a leakage current check and a high
voltage check. It is non-destructive to the equipment under test, and can be accomplished in a
short time.
Safety Precautions
The dielectric withstand test generates voltages of up to 2000 volts ac at potentially lethal
current levels. Currents of as little as 5 mA at 120 volts can cause death, and the HT-2000P is
capable of generating 20 mA at up to 2000 volts. The HT-2000P has been designed to minimize
exposure to high voltages. However, the potential for serious injury or death exists and personnel
should be aware when they conduct this test.
Test Personnel
Personnel require special training to conduct the dielectric withstand test. They should
understand electrical fundamentals clearly, and be aware that high voltage is adept and creative at
completing a path to ground. Instructions should include a warning against any metal jewelry.
Operators should not allow others in the testing area, especially when tests are being conducted.
Organization is to be stressed. The operator should keep the area free of unused leads and
equipment.
Testing Area
The area used for conducting the dielectric withstand test should be as remote as possible
from normal production line activities. Only personnel actually conducting the test should be
allowed in the area, and it should be taped or roped off to preclude casual entry by other
employees. In addition, the area should be marked "WARNING - HIGH VOLTAGE TESTING"
or the equivalent to warn others of the nature of the testing taking place.
The bench being used should be non-conductive, and any exposed metal parts should be
tied together and grounded. If a conductive surface must be used, it should be grounded.
Because of sparking during a dielectric test failure, it is not safe to conduct dielectric
withstand tests in combustible atmospheres.
It is imperative that a good ground be provided to the HT-2000P. Before connecting the
HT-2000P, ensure that a low-resistance ground is provided by the building wiring. If the HT-
2000P is used on a high-resistance grounding circuit, dangerous high voltages may be present to
the operator. In addition, the power to the Testing Area should be provided with an easily
reached shutoff switch which can be actuated by personnel outside the Area if needed.

5
Safety Techniques
The high voltage circuit of the HT-2000P can be shut off at any time by pressing the
RESET button. The HT-2000P has been provided with a Reset switch to provide an unarmed
"Standby" setting when it is energized, but idle. When the red RESET button is lit. the tester will
not provide high voltage until the RESET button and the TEST button have been pressed in
order. To prevent inadvertent operation, the operator should be instructed not to press the
RESET button until the test is ready.
The HT-2000P is equipped with a Ground Continuity Check which will not allow high
voltage to be applied if the Test Return Lead is not properly connected. This is an important
safety feature and should not be defeated unless two wire products are being tested. In that event,
it is imperative that the operator make absolutely sure the Test Return Lead is properly connected
to the equipment being tested. If the lead is not properly connected, a dielectric withstand test
failure may energize exposed dead metal of the equipment being tested. Additionally, the HT-
2000P may not recognize the failure. The test will continue for its normal length of time, and the
HT-2000P may show a "PASS".
The HT-2000P has been designed for one-touch operation with the right hand. If
possible, it should be set up to the left and in front of the equipment under test. The equipment
under test should be connected to the HT-2000P and then left alone by the operator. After the
operator is clear of the Tester and the equipment under test, he should press the RESET Button,
then the TEST Button, with his right hand. This will allow the greatest separation between the
operator and the test being conducted.
The HT-2000P is designed to bleed the high voltage away after the test has concluded. In
order to ensure that any voltage present in the equipment being tested has been completely bled
away, the operator should not unplug the equipment under test from the HT-2000P until the front
panel meter reads zero volts.
Using the HT-2000P Dielectric Withstand Tester
The dielectric withstand test involves high voltage and caution should be exercised when
using the tester. The tester's return lead is connected to ground potential and when properly
connected to the equipment being tested, it will guard against the operator contacting high
voltage. Always make sure the return lead is firmly connected to exposed dead metal. In the
sections below, the three tests are discussed.
Ground Check
The Ground check ensures that the grounding pin of the power supply cord is properly
connected to the exposed dead metal of the chassis. If this connection is absent, the exposed dead
metal of your product could be at line potential indefinitely after an internal wiring fault, causing
risk of shock to anyone touching it.
If the green Ground OK LED lights and the test continues, the connection between the
grounding pin and the exposed dead metal of the equipment being tested has a resistance of below
three ohms*.
Ground Check Failures
If the red Ground Open LED lights, the buzzer sounds, and the test is terminated. The
connection between the grounding pin of the attachment plug cap and the exposed dead metal of
the chassis has a resistance of greater than three ohms*. This indicates a problem with the
connection of the HT-2000P to the equipment being tested, or that the ground connection in the
equipment being tested is defective. The connection to the tester should be checked by removing
the Test Return Lead clip from the equipment under test and reconnecting it, taking care to make

6
a good connection. The unit should then be retested. If a failing result is repeated, the connection
between the power supply cord ground pin and the chassis of the equipment being tested should
be checked and reworked until a passing result is obtained.
*Special calibrations available by internal adjustment. Must be performed by qualified service
personnel. See Sec. 5.
Defeating the Ground Check
The Ground check can only be conducted on equipment using a three wire grounded
power supply cord. Some equipment, such as most portable lamps and all double insulated tools,
have only a two wire power supply cord, so the Ground test cannot be conducted.
Please note that defeating the Ground check should not be done except when
necessary to test two-wire devices. The Ground check feature provides an extra level of
operator safety because high voltage will not be applied if the Test Return Lead is not
properly connected to the exposed dead metal of the equipment being tested. If the Test
Return Lead is not properly connected, a dielectric withstand failure may energize exposed
dead metal. Additionally, the HT-2000P may not recognize the failure. The test will
continue for its normal length of time, and the HT-2000P may show a "PASS".
To allow the HT-2000P to test equipment using a two wire power supply cord, the
Ground Check can be defeated by turning the rear panel Ground Check switch to the Off position.
To remind the operator that the Ground Check is not being conducted, both the green Ground
OK and red Ground Open LED's will be lit continuously during the test. When testing with the
Ground Check switch in the Off position, the operator must ensure that the Test Return Lead is
properly connected to exposed dead metal of the equipment being tested for safety and to ensure
that the HT-2000P properly reports all failures.
Leakage Test
The HT-2000P leakage test uses a separate low-frequency circuit to check for excessive
leakage between primary power components and ground. There is not a specific leakage current
level pass/fail requirement at this time for most equipment, however, higher than normal leakage
current on a particular part may indicate an assembly or component problem in the primary
circuit.
The leakage current is also monitored by the HT-2000P to ensure that excessive leakage
does not keep the tester from developing full voltage required for the high voltage test. The HT-
2000P will provide full voltage at any leakage current level up to 20 mA. The leakage current
trip level is adjustable on the rear panel.
The leakage test is conducted by shorting the power and neutral conductors of the power
supply cord and applying high voltage between them and the exposed dead metal of the chassis of
the equipment being tested.
Excessive leakage current is not grounds for failure of the dielectric withstand test.
Leakage current is a normal result of capacitance in the primary circuit between neutral or line
conductors and ground. (In dielectric tests of some larger electric motors, leakage currents of as
high as 95 mA are considered acceptable by safety agencies.) However, leakage currents higher
than normally anticipated for a particular model should not be ignored. This indicates problems
of low resistance up to a short circuit between line/neutral and ground, and failures should be
investigated. Failure modes are discussed below.
If the green Full Voltage LED lights and the test continues, the leakage current was
below the amount set by the rear panel adjustment.

7
Sporadic Leakage Current Failures
If the red Excess Leakage LED lights, the buzzer sounds, and the test is terminated, the
leakage current delivered to the equipment being tested was over the amount set by the rear panel
adjustment. If other equipment of the same type routinely passes this test, there may be a
problem with the primary circuit of the example being tested. The unit should be checked and
reworked if necessary.
Chronic Leakage Current Failures
AC Dielectric Withstand testing charges all primary circuit capacitors connected line to
ground or neutral to ground. The current flowing through these capacitors is defined as leakage
current. If almost all examples of a model of equipment are not passing the leakage current test,
we recommend that the leakage current limit be increased by resetting the leakage current level
on the rear panel to a higher level.
If the leakage current adjustment of the HT-2000P is set to 20 mA and almost all
examples of the model being tested are still failing, the primary circuit capacitance of the
equipment may be too high to allow the AC dielectric withstand test to be used. This is due to the
AC voltage charging all capacitors connected between primary voltage and ground. If the overall
value of these capacitors cause a leakage current of more than 20 mA to flow at the desired test
voltage, the HT-2000P cannot generate full voltage, and cannot successfully conduct the
dielectric withstand test.
However, a DC dielectric withstand test is acceptable for most categories of equipment
and will not cause leakage through the primary circuit capacitors. A DC voltage dielectric
withstand tester, such as the Compliance West USA model HT-2800, may allow successful test of
models chronically failing the HT-2000P leakage current test.
High Voltage Dielectric Withstand Test
This test checks for insulation system breakdowns between the primary and ground
circuits. The HT-2000P uses a separate high-frequency transformer circuit to check for and
detect arc breakdowns.
The dielectric withstand test is conducted by shorting the line and neutral conductors of
the power supply cord and applying high voltage between them and the exposed dead metal of
the chassis of the equipment being tested. The duration of the test is controlled by the test time
control on the back panel. The test time is counted from the time the Full Voltage LED is lit to
the completion of the test.
If the green Hipot Pass LED lights, the test cycle has been successfully completed. The
equipment under test is in accordance with the preset test parameters. The HT-2000P is ready to
test the next piece of equipment.

8
High Voltage Dielectric Withstand Test Failures
If the red Hipot Fail LED lights, a problem has been found with the insulation system
between primary and ground. The equipment under test should be examined, reworked and
successfully tested before being shipped.
High Voltage Discharge
The HT-2000P is designed to discharge the high voltage after completion of the dielectric
withstand test. The equipment being tested should remain connected to the HT-2000P until the
voltage has discharged to a safe level to protect the operator and also to ensure that there is no
energy stored in the tested equipment.
Testing Equipment with non-Standard Plugs or Pigtail Operation
The front panel of the HT-2000P is provided with a NEMA Type 5-15R receptacle,
suitable for testing cord-equipped single-phase products designed for use on a 15 amp branch
circuit in North America. For other types of products, a different receptacle type or pigtail leads
may be required. Various adapters and pigtail leads are available from Compliance West USA, or
you can make your own. If tests of this type are contemplated, call us for information.

Initial Checkout Procedure
The following procedure will verify that the HT-2000P is working correctly. We
recommend that this procedure be conducted periodically to ensure proper operation of the tester.
(A Compliance West HTT-1 function tester may also be used to verify the HT-2000P is working
correctly.)
The following items are needed to conduct this procedure:
- A three inch piece of 18 AWG insulated hookup wire with each end stripped back ½".
- A extra test lead with a banana plug on one end. The other end will be clipped to the
alligator clip end of the black test lead supplied with the HT-2000P.
CAUTION
High voltage (up to 2000 Volts AC) generated by the HT-2000P is exposed
during this test. A risk of shock exists. Exercise care when using the HT-
2000P.
