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-2000 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-2800 Dielectric Withstand
Tester. Before proceeding with testing, the HT-
2800 Tester should be set up for production line
testing. See Section above before continuing.
CAUTION
High voltage is generated by the
HT-2800. Although the chassis
of the equipment under test is
grounded by the HT-2800, a risk
of shock exists. Exercise care
when using the HT-2800.
Daily Operation Test
The operation of the HT-2800 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-2800. Contact the factory
for details.
Testing
This section describes how the Tester is used to
conduct a test. Before a Test can be conducted,
the tester must be properly set up. Please see
Section "Setting up the HT-2800 for Production
Line Testing. In addition, we recommend that
you read Section 1, "An Introduction to
Dielectric Withstand Testing with the HT-2800".
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.
Test Verification procedure when using
the HTT-1 function checker:
1.
Connect the HT-2800 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-2800 is ready to test.
2.
Connect HTT-1 to the HT-2800 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-2800 and verify
passing result on the HT-2800.
5.
Set Continuity switch on the HTT-1 to
‘FAIL’; set both other switches to ‘PASS’.
6.
Run a test with the HT-2800 and verify
continuity failure on the HT-2800.
7.
Set Leakage switch on the HTT-1 to
‘FAIL’; set both other switches to ‘PASS’.
8.
Run a test with the HT-2800 and verify
excess leakage failure on the HT-2800.
9.
Set Hipot switch on the HTT-1 to ‘FAIL’;
set both other switches to ‘PASS’.
10.
Run a test with the HT-2800 and confirm
high voltage breakdown by watching for
spark in Arc Detect window of HTT-1;
verify dielectric breakdown failure on the
HT-2800.
Test Verification procedure when NOT
using the HTT-1 function checker:
1.
Connect the HT-2800 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-2000 is
ready to test.
2.
Plug the black test lead into the
Return
receptacle on the front panel of the HT-
2800.
3.
Plug the power supply cord of the
equipment being tested into the
Device
receptacle on the front panel of the HT-
2800.
4.
Connect the alligator clip end of the test
return lead to an exposed metal part on the
chassis of the equipment to be tested.
5.
Make sure the power switch on the
equipment being tested is in the 1 or ON
position.
