 Warning
To avoid exposure to dangerous voltage, this test must be done
correctly. Do not perform this test unless you are qualified to
do so.
The UUT Touch Pad measures the potential between the operator and the UUT PE input
jack. If the potential exceeds the 100 V, the  (Warning) symbol illuminates. Perform
the following test to verify that the Touch Pad circuit is working properly (refer to
Figure 3):
1. Connect the PE input jack of the Tester to the HI terminal of the 5320A V, HIΩ,
mA~ Output.
2. Connect the 5320A LO terminal to a test lead with test probe attached at the opposite
end.
3. Set the 5320A output for 100 V, 50 Hz. Leave the 5320A in Standby mode.
4. Touch the test lead’s probe tip to the UUT Touch Pad, as shown in Figure 3.
5. Set the 5320A to operate and note that the  symbol illuminates on the Tester’s
front panel.
6. Set the 5320A to standby and remove the test leads and probe from the Tester and
calibrator.
