Kikusui HP21-TOS User manual

The HP21-TOS is a probe that is connected to the TOS3200 Leakage Current
Tester for measuring the touch current. The easy-to-handle design cuts down on
the time needed to connect wires to the EUT. It provides fingertip control to start
the test.
• The HP21-TOS is designed to be used with the TOS3200 Leakage
Current Tester. Be sure to thoroughly read the warnings and
precautions given in the TOS3200 manuals before use.
Safety Precautions
Touching the contact pin will cause electric shock.
Never touch the contact pins while the DANGER LED is illuminated.
Be sure to connect the control cable.
Do not execute the test using the START switch on the tester without
connecting the control cable.
This probe cannot be used with other TOS series.
This probe is designed to be used only for the TOS3200 Leakage Current
Tester. It cannot be used with other TOS series even if the connector fits.
Do not swing the probe.
Do not pull on the probe cable or wind the cable around your body.

Preliminary inspection
Check the following items before connecting the probe.
If you find any abnormalities in the preliminary inspection, stop using the probe
immediately and contact your Kikusui agent or distributor for repairs.
• Check that there are no tears, cracks, or breaks in the insulation of the probe
cable or test lead.
• Check that the START switch can be pressed normally.
• Check that the contact pin is not damaged or loose.
Adjusting the pin
It is dangerous if the pin is loose. If the pin is loose, tighten the pin as referred to
the procedure below.

nected to the TOS3200.
2Turn the holder counterclockwise.
3Turn the pin clockwise all the way.
4Turn the holder clockwise all the way.
When using the alligator clip
When you attach the included alligator clip to the test lead wire, remove the cap
beforehand. To remove the cap, use a flat-blade type pocket screwdriver. Insert the
tip of the screwdriver under the pawl of the cap, lift the pawl, and remove the cap.
Connecting to the TOS3200
When the probe is connected to the TOS3200, the TOS3200 becomes to the
equivalent condition as when the STOP switch is pressed, and the READY
indicator on the display turns off.

Measurement Procedure
Set the necessary measurement conditions in advance by referring to the
TOS3200 user’s manual.
The connection between the EUT and the probe/test lead varies depending on
the type of touch current to be measured and the EUT class. See Table 4-1, “Test
lead connections for the type of TC measurement”, chapter 4, “TC and PCC
Tests” in the TOS3200 user’s manual. When referring the user’s manual, read
“test lead A” as “cable A.”
Connect test lead B to the test point on the EUT. For details, see “Connecting the
Test lead (TL21-TOS)”, chapter 4, “TC and PCC Tests” in the TOS3200 user’s
manual.

Starting the measurement
•There is a danger of electric shock. Never touch the
contact pin while the DANGER LED is illuminated.
When you connect the probe to the TOS3200, the READY indicator on the
display turns off. Even though, you can start the test using the START switch on
the probe.
Keep holding down the START switch. If you release the switch, the
measurement is aborted. The DANGER LED illuminates while the
measurement is in progress. The DANGER LED illuminates (or turns off)
simultaneously with the DANGER lamp on the TOS3200.
When you connect the probe to the TOS3200, the START switch on the panel is
disabled. The STOP switch remains enabled.

WARNING

HP21-TOS 5
Stop using the probe if broken
The probe is broken in the following cases. For your safety, immediately turn
the TOS3200 POWER switch off and stop using the probe.
•The DANGER LED does not illuminate.
•The DANGER LED illuminates differently from the DANGER lamp on the
TOS3200.
•The DANGER LED does not turn off even if you release the START switch.
There is a danger of electric shock.
•Do not allow other people to use the probe until it is
repaired.
•Be sure to request repairs to your Kikusui agent or dis-
tributor.
Maintenance
Periodic maintenance and inspection are essential to maintain the initial
performance of the product over an extended period.
•Be sure to remove the probe from the tester for maintenance work.
•Do not use volatile chemicals such as benzene or thinner as they may
discolor the surface, erase printed characters, and so on.
Cleaning
If the probe needs cleaning, gently wipe using a soft cloth with water-diluted
neutral detergent.
Periodic inspection
The cable, contact pin, and test lead of the probe are consumable parts. We
recommend you have the probe inspected by a Kikusui service engineer once a
year. Contact your Kikusui agent or distributor for an inspection.
