Cleaning
CAUTION
To avoid equipment damage, turn off the RM2611
Electrode Resistance Meter before connecting or
disconnecting the RM9005 Connection Cable.
Preparations
Remove the four mounting screws from the top of the
RM9004 Test Fixture and remove the test xture from the test
xture case.
After removing the test xture from the case, do not place it
on a surface with the probe surface facing down.
Assembly
Place the RM9003 Press Unit’s up/down lever in the
1
raised position.
Slide the RM9004 Test Fixture into position along
2
the RM9003 Press Unit’s test xture insertion rails.
Push the test xture toward the rear until it won’t go
any further.
Pull the test xture lock lever toward you and
3
downward and then let go to lock.
The RM9004 Test Fixture will lock in place.
Connect the grounding cable on the rear of the
4
RM9003 Press Unit to the ground terminal on the
RM9004 Test Fixture.
Connect the connector on the RM9004 (the female
5
side) and connector on the RM2611 (the male side)
using the RM9005 Connection Cable and screws
that hold it in place.
Secure the RM9005 Connection Cable in place with
6
the cable clamp.
There are screws for attaching the cable clamp on the
left and right sides of the RM9003 Press Unit. Choose
the appropriate side based on the position of the
device.
IMPORTANT
• When connecting the RM9005 Connection Cable, insert the
cable into the connector rmly and tighten it in place with screws.
If the screws loosen, the resulting poor contact could cause a
measurement error.
• Exercise care not to lose the test xture case’s mounting screws,
which you will need in order to store the RM9004 Test Fixture
during transport.

CAUTION
• Use a compressed air pressure of 207 kPa (2.1 kgf/
cm2, 30 psi) or less.
• Wear a dustproof mask and dustproof goggles while
cleaning the device.
IMPORTANT
The probes are extremely thin. Do not clean them with anything
other than air. Tighten the test xture clamp knob securely so that
it is not loose.
Cleaning the probe
Verify that the test xture lock lever is in the
1
lowered position.
Rotate the test xture clamp knob counterclockwise
2
to disengage the lock.
While doing so, rotate the test xture clamp knob
toward the UNLOCK position until the screw is fully
removed while holding the RM9004 Test Fixture still.
The base (bottom) of the RM9004 Test Fixture will
gradually move so that it faces toward the front of the
unit.
Once the base of the test xture is fully facing
3
toward the front, pull out the maintenance plunger
to lock the RM9004 Test Fixture in place.
Remove dust from the probes using the
4
compressed air gun or blower.
Repeat the above procedure in reverse after
5
cleaning to return the test xture to its original
state.
