Information
                                    The instrument is a bench-type Dielectric
Withstand Tester with DC Output, designed for
production line testing.
The HT-2800 features automatic one-button
operation, with numerous safety features
designed to protect the operator:
?
 The Return Lead is directly connected to
ground potential for operator safety.
?
 In case of trouble, the test can be
immediately terminated at any time by
pressing the RESET button.
?
 Before the test can commence, the unit
must be armed by pressing the RESET
Button. The test will not begin until the
TEST Button is pushed.
?
 If a failure is encountered, the high voltage
is immediately cut, a buzzer sounds, and
any voltage stored in the equipment being
tested is bled off by a resistor bank in the
HT-2800. Voltage discharge progress is
shown by the front panel meter.
?
 Failure modes are shown by the front panel
LED's for quick troubleshooting.
Convenience and testing features include:
? Test results are determined quickly, without
operator intervention.
? Operator instructions are printed on the rear
panel for quick reference.
? The HT-2800 allows custom setups for
voltage ramp, test time and leakage limit.

?
The continuity check can be defeated by a
switch on the rear panel for testing of
products using a two wire power supply
cord.

Voltage is discharged by resistor bank within
the HT-2800 upon test completion.
Discharge progress is shown on the front
panel meter.
Ground continuity pass/fail resistance level
is adjustable during the annual calibration
procedure.
A 120kohm resistor is supplied on the rear
panel for leakage current checks and
adjustment.
The HT-2800 meets all safety agency criteria for
automatic production line dielectric withstand
testers.



An Introduction to Dielectric Withstand Testing with the HT-2800
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 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
2800 volts dc at potentially lethal current
levels. Currents of as little as 5 mA at 120 volts can cause
death, and the HT-2800 is capable of generating 5
mA at up to 2800 volts. Because there is no zero volts
crossing point as there is for ac voltage, dc voltage is
considered the more dangerous of the two. It is more likely
that a person will be thrown clear or be able to
extricate himself from ac because of the zero crossing. The
HT-2800 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.
