6 Maintenance & Care
The CR:800C is a precision measurement instrument and should be treated with care.
Do not allow the instrument to be exposed to substances which may cause damage to
the components of the unit. If the instrument is to be used in an environment where
particles such as dust may come into contact with the instrument, always use a
Windshield (UA:237) to protect the microphone capsule.
The CR:800C is not waterproof and should not be used in situations where moisture will
form or condense on the microphone capsule or the instrument body. If using the
CR:800C outdoor, use a suitable outdoor measurement kit which has been specifically
designed to protect the instrument.
If the CR:800C becomes dusty, wipe it down with a cloth that is lightly dampened with
water or a mild detergent. Do not use aromatic hydrocarbons, chlorinated solvents, or
methanol-based fluids when wiping down the meter.
Do not clean the microphone capsule. Do not remove the microphone grill as this can
cause severe damage to the membrane. Physical damage to the microphone capsule is
not covered by the instrument warranty.
If you experience any problems with the operation of the instrument, refer to page 53
for basic troubleshooting. If this does not solve the problem, contact Cirrus Research
plc or your local representative for further assistance.
