AC Hi-Pot Test
Perform the AC hi-pot tests only on the ECG/RESP front panel connector
of the device under test.
CAUTION
Never attempt to perform this test on any of the other
front panel connectors of the device under test. Damage
to the device under test may occur if this test is
performed on any of the other front panel connectors.
1.
Install the ECG test body in the ECG/RESP front panel connector of
the device under test.
2.
Connect one end of a high voltage lead to the exposed lead of the test
body.
3.
Connect the other end of the high voltage lead to the AC OUT
connector of the AC/DC Hi-Pot Generator.
WARNING
The following step will cause high voltage (1500 V AC) to
appear at the test body.
4.
Set the HIGH VOLTAGE switch to ON. The high voltage indicator
should illuminate with this action.
NOTE
During this test, watch the analog meter to ensure the
current level never exceeds 2ÊmA. If it does, the unit has
failed the test and must be repaired then tested again.
5.
Slowly turn the RAISE VOLTAGE selector to 1500 volts.
6.
Wait for 60 seconds. If the breakdown warning lamp illuminates or
the buzzer activates before the time expires, then the unit has failed
the test and should be repaired then tested again.
7.
Slowly turn the RAISE VOLTAGE selector to 0 volts.
8.
Set the HIGH VOLTAGE switch to OFF. The high voltage indicator
should turn off.
9.
If the device under test fails, repairs must be made and the unit must
be tested again.
10. This completes the AC hi-pot test.
