Usage Notes
Usage Notes
Observe the following precautionary information to ensure that the instrument can be used
safely and in a manner that allows it to perform as described in its specifications.
Use of the instrument should confirm not only to its specifications, but also to the specifications of all accessories, options, and other equipment in use.
Do not use these leads on a circuit with a voltage exceeding the maximum input voltage of the tester to which they are connected. In any
event, do not use on a circuit exceeding 60 V DC. There is a danger of
electric shock.
• The ends of the 9455 Pin Type Lead are sharp. Be careful to avoid injury.
• Before use, verify that the insulation on leads is not-damaged and that
no metal is exposed. If you find any damage or failure, replace the 9455
Pin Type Lead with those specified by Hioki, as the product will not be
able to make accurate measurements or send/ receive data otherwise.

1.1Product Overview
The ends of the 9455 Pin Type Lead have an extremely fine four-electrode construction,
developed for testing for raised leads on mounted ICs. They can therefore be used for
accurate measurement of resistance on small-dimensioned items.

Chapter 2 Method of Measurement
Method of
Measurement
Connect the leads correctly to the tester. For details, refer to the instructions supplied with
the tester.
For testers with zero adjustment, carry out the zero adjustment with the standard leads
connected, then remove the standard leads and connect these leads to carry out measurement.
Chapter 2
Hold these leads lightly against the two sides of the item to be tested.
After the sense electrode contacts the item, pushing the probe in by another 0.2 mm brings
the
source electrode into contact, and allows measurement to start.

These leads are a precision instrument. Take all reasonable care in handling them.
• Treat the tips of the probes carefully; do not press them too hard against
the item being tested or anything else. Because of the precision construction, this could cause the tips to break or bend.
• Hold the probes perpendicularly against the tested item. If pressed at an
scraped off material may prevent the four-terminal function from
angle,
operating correctly.
• While the probe is pressed against an item being tested, do not move it
sideways, a

Maintenance and
Repair
If you find any damage to the instrument, please contact your authorized Hioki distributor
or reseller for repair.
Although repairs by customers are discouraged, you can replace the 1172-44 4-Terminal
Probe (R-arm) with a new one, which can be purchased separately, by following the procedure below.
Procedure
Fix the part of the spring of the 1172-44 4-Terminal Probe with adhesive (epoxy
1.
resin or other types) and so on.
It is to make it elastic only by 1 step by this lead though 1172-44is elastic by 2 steps.

First, pass the shielded wire through the probe body. Then, solder the shielded

wire to the two lead wires connected to the 4-Terminal Probe with the end cap
installed.
The solder joints should be offset, to reduce the possibility of a short-circuit. Finally, reinforce the soldered portions with insulating tape or similar, to prevent short circuits.
Reassemble the 4-Terminal Probe (R-Arm), end cap.
5.
While pinching the end cap, turn the probe body to assemble them.
Finally fix the leads with the pan-head screw.
6.
Tighten the pan-head screw until the head of the screw touches the probe shaft. Do not
overtighten - doing so will tear the screw thread.
Refer to the "Names of Parts" (p.3) diagram, and check the connectivity of the banana
plugs and probe tips using a tester
connectivity function.
