Operating Techniques
The following paragraphs describe how to operate your HT-3000P Dielectric Withstand
Tester. Before proceeding with testing, the HT-3000P tester should be set up for production line
testing. See Section above before continuing.
CAUTION:
High voltage is generated by the HT-3000P. Although the chassis of the
equipment under test is grounded by the HT-3000P, a risk of shock exists.
Exercise care when using the HT-3000P.
Daily Operation Test
The operation of the HT-3000P should be audited daily by conducting the tests described
in the
Initial Checkout Procedure
section of this Manual. Compliance West also offers the
model HTT-1, which can be used to quickly verify the operation of your HT-3000P. Contact the
factory for details.
Testing
This section describes how the HT-3000P is used to conduct a hipot test. Before
continuing, we recommend that you read Section 1, "An Introduction to Dielectric Withstand
Testing with the HT-3000P". It contains valuable safety, operation, and test result evaluation
information which can help you conduct the test safely and correctly. The test can be stopped
immediately at any time by pressing the red
RESET
button on the front panel.
Test Verification procedure when using the HTT-1 function checker:
1.
Connect the HT-3000P 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-3000P is ready to test.
2.
Connect the HTT-1 to the HT-3000P tester using the cables supplied with the HTT-1.
3.
Set all three switches on the HTT-1 to ‘PASS’.
4.
Run a test with the HT-3000P and verify passing result on the HT-3000P.
5.
Set the
Ground
switch on the HTT-1 to ‘FAIL’; set both other switches to ‘PASS’.
6.
Run a test with the HT-3000P and verify
Ground Open
failure on the HT-3000P.
7.
Set
Leakage
switch on the HTT-1 to ‘FAIL’; set both other switches to ‘PASS’.
8.
Run a test with the HT-3000P and verify
Excess Leakage
failure on the HT-3000P.
9.
Set
Hipot
switch on the HTT-1 to ‘FAIL’; set both other switches to ‘PASS’.
10.
Run a test with the HT-3000P and confirm high voltage breakdown by watching for spark
in Arc Detect window of HTT-1; verify
Hipot
Fail
failure on the HT-3000P.
Test Verification procedure when NOT using the HTT-1 function checker:
1.
Connect the HT-3000P 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-3000P is ready to test.
2.
Plug the black test lead into the
Return
receptacle on the front panel of the HT-3000P.
3.
Plug the power supply cord of the equipment being tested into the
Device
receptacle on the
front panel of the HT-3000P.
4.
Connect the alligator clip end of the black return lead to an exposed metal part on the
chassis of the equipment to be tested.
