2) Model HP01A-TOS/HP02A-TOS High Voltage Test Probe
The High Voltage Test Probe renders a threefold operating safety, namely, the test voltage is not
delivered unless you squeeze with one hand the slide lever of the grip of the probe and pull the trig-
ger and you press with the other hand the switch on top of the probe, thereby occupying your both
hands. As you release even a single one of these, the probe immediately and forcefully delivers the
STOP signal to cut off the test voltage.
Voltage ratings
4 kVAC rms 50/60 Hz
5 kVDC
Length of cable
HP01A-TOS: Approx. 1.8 m
HP02A-TOS: Approx. 3.5 m
•
The maximum voltage ratings of the probe is 4 kVAC rms or 5 kVDC. Never let it
subjected to voltages higher than these limits.
•
Do not connect the probe to or disconnect it from the DUT while letting it deliver the
test voltage—if you do this, the DUT may be damaged. If you disconnect the probe
from the DUT while letting it deliver the test voltage, the items of the tested circuit
may remain charged up to 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 a test in compliance to the UL Standard by using the probe, set the FAIL
ALARM mode switch (DIP switch on the rear panel) of the Tester to ON. If you have
set this switch to ON, the Tester is not reset from the FAIL alarm has gone out even
when you have released your hand from the probe. To reset it, you have to press the
STOP switch of the Tester. Thus, you will be securely informed of the FAIL alarm.
