5. After the TEST button is pressed, the voltage will ramp and hold. Set the Voltage Adjust
control on the rear panel to the desired voltage.
6. If tamperproof operation is desired, we suggest placing a calibration-style label over the
voltage adjust hole.
7. Check the position of the Ground Check switch, and reset the test time using the procedure
Adjustment of the High Voltage Test Time .
Adjustment of the High Voltage Test Time
This procedure sets the length of time the HT-2000P will conduct the high voltage test. The
test time is specified by the safety agencies and is tied to the test voltage. Most safety agencies
will allow a much shorter test (usually 1 second vs. 1 minute) if the voltage is increased by 20%.
The HT-2000P is factory set for 2 seconds. Consult the safety agencies for the test time for the
type of equipment being tested. If a different test time is required, use this procedure to set it.
1. Defeat
the Ground Check by turning the rear panel switch Off.
2. Connect the HT-2000P to a correctly rated source of supply and turn the power switch to
the I or ON position. Push the
RESET button. The yellow TEST indicator should light,
indicating that the HT-2000P is ready to test.
3. On the rear panel turn the Test Time potentiometer. As soon as the potentiometer starts
turning, the meter will display “d” and the value can be set in 1 second increments from 1 to
60 seconds.
4.
If tamperproof settings are desired, the Leakage Limit control shaft may be pulled away
with a slight tug. (It may be reinserted for future adjustments.)
5. Check the position of the Ground Check switch before conducting testing.
Setting the Ground Check Switch
This switch controls whether the Ground Test is conducted between the chassis and the
power supply cord grounding pin of the unit being tested. The safety agencies require that this
test be conducted on all equipment using a three-wire power supply cord. For other types of
equipment, such as some portable lamps and all double-insulated equipment, there are only two
wires in the power supply cord and the ground continuity check is waived by the safety agencies.
If the power supply cord of the equipment being tested has only two pins, the Ground
Check switch should be set to the Off position. When the Ground Check switch is turned Off,
both the green Ground OK and red Ground Open LED's on the front panel are lit as a reminder
to the operator that the ground continuity test is not being conducted.
If the power supply cord of the equipment being tested has three pins, the Ground
Check switch should be set to the On position.
When testing with the Ground Check switch Off, the operator must ensure that the
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.
The small size of the Ground Check switch will allow a calibration-type adhesive label
to be placed over it to allow for tamper-proof operation.
Operating Techniques
The following paragraphs describe how to operate your HT-2000P Dielectric Withstand
Tester. Before proceeding with testing, the HT-2000P tester should be set up for production line
testing. See Section above before continuing.
