Setting the Failure Shutdown Switch
Use extreme caution when using this feature
The Breakdown Detect switch allows the operator to continue testing after a failure is
encountered. This allows the operator to find the breakdown point, but
all arc shutdown
circuitry in the HT-5000P ac/dc 200mA is disabled when the Breakdown Detect switch is in
the DEFEAT position
. The excess leakage limit may stop the test. Also the tests may be
terminated at any time by releasing the TEST button.
WARNING: Testing with the Shutdown Limit switch in the DEFEAT position is
extremely hazardous. The HT-5000P ac/dc 200mA can generate lethal levels of voltage and
current. Therefore, care should be taken in examining the equipment being tested, to locate
areas of failure while the HT-5000P ac/dc 200mA is operating.
Operating Techniques
The following paragraphs describe how to operate the HT-5000P ac/dc 200mA
Dielectric Withstand Tester.
CAUTION:
High voltage is generated by the HT-5000P ac/dc 200mA. Although the
chassis of the equipment under test is grounded by the HT-5000P ac/dc 200mA, a risk
of shock exists.
Testing Products
This section describes how to conduct a test. Testing can be terminated at any time by
pressing the RESET button.
1.
Set up tester to correct parameters for unit to be tested using the previously described
procedures.
2.
Connect the HT-5000P ac/dc 200mA to a correctly rated source of supply and turn it on.
3.
Plug the black lead into the Return receptacle. Plug the red lead into the Output receptacle.
4.
Connect the alligator clips of the leads across the circuit or part being tested. Keep in mind
that the black lead is connected to earth ground.
5.
Press the RESET button. The TEST button should light, indicating that the HT-5000P ac/dc
200mA is ready to test.
6.
Set the VOLTAGE ADJUST Knob to minimum in order to disarm the Zero Voltage Start
safety feature.
7.
Push the TEST button. The HT-5000P ac 200mA will energize the high voltage output.
8.
After the FULL VOLTAGE indicator lights, use the Voltage Adjust knob to set the desired
output.
9.
If the Shutdown Limit switch is set to ON, and if the leakage current of the circuit under
test exceeds the alarm value, the Excess Leakage indicator will light and the test will
terminate.
