Cleaning the System
RM9004 Test Fixture
CAUTION
• Do not operate the up/down lever while cleaning the device. Doing so could cause the
RM9004 Test Fixture to lower while you’re cleaning it, resulting in injury or damage to
the device.
• Contacting the probes with cloth, cotton swabs, or other supplies while cleaning the
device could deform the pins, increasing the error component of measurement results
or making accurate measurement impossible.
• Use a compressed air pressure of 207 kPa (2.1 kgf/cm
2,
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.
•The RM9004 Test Fixture’s probes are consumable parts. They require periodic replacement but are not
customer-replaceable. Please contact your authorized Hioki distributor or reseller for more information.
You will need:
A compressed air gun or blower (of the type used to clean
camera lenses)
