1-6 TOS5051A/5050A
Model HP01A-TOS/HP02A-TOS high voltage test probe
The high voltage test probe renders a three-fold oper-
ating safety. The test voltage is not delivered unless
you squeeze with one hand the slide lever of the grip
of the probe and pull the trigger while you press with
the other hand the switch on top of the probe. If you
release your hand, the probe immediately delivers a
STOP signal to cut off the test voltage.
• The maximum voltage rating of the probe is 4
kVACrms or 5 kVDC. Never apply voltages
exceeding the voltage rating.
• Do not connect the probe to or disconnect it from the DUT while the test
voltage is being delivered. If you do, the DUT may be damaged. If you dis-
connect the probe from the DUT while the test voltage is being delivered,
the DUT will remain charged at the high test voltage. Before connecting
the probe to the DUT, be sure that the test voltage is OFF (the LED on top
of the probe is OFF); before disconnecting the probe from the DUT, be
sure that the test voltage is OFF (the LED is OFF).
• If you need to perform a test in compliance to the UL Standard by using the probe,
turn the FAIL MODE switch (DIP switch on the rear panel) of the tester to ON. If
this switch is ON, the tester behaves in the following manner and you can accu-
rately confirm the FAIL status. When a test is terminated due to a failure, the FAIL
status on the tester is not reset even when you release the probe. To reset the FAIL
status, you must press the STOP switch on the tester. For details, refer to Section
6.5.4, “FAIL MODE Switch” (page 6-30).
Model PL01-TOS warning light unit
This unit indicates that the tester is in the TEST-ON status (delivering the test voltage).
Model BZ01-TOS buzzer unit
This unit may be used when the sound generated by the buzzer housed in the tester
is insufficient. This unit can be driven by the FAIL status signal of the tester.
