Maintenance
Instrument maintenance consists of keeping the instrument clean and
periodically checking the batteries and the calibration. The Model 2224-1
instrument may be cleaned with a damp cloth (using only water as the
wetting agent). Do not immerse instrument in any liquid. Observe the
following precautions when cleaning:
1.
Turn the instrument
OFF
and remove the batteries.
2.
Allow the instrument to sit for one minute before accessing
internal components.
R
ECALIBRATION
Recalibration should be accomplished after maintenance or adjustments
have been performed on the instrument. Recalibration is not normally
required following instrument cleaning, battery replacement, or cable
replacement.
Note:
Ludlum Measurements, Inc. recommends recalibration at
intervals no greater than one year. Check the appropriate
regulations to determine required recalibration intervals.
Ludlum Measurements offers a full-service repair and calibration
department. We not only repair and calibrate our own instruments, but most
other manufacturers’ instruments as well. Calibration procedures are
available upon request for customers who choose to calibrate their own
instruments.
B
ATTERIES
The batteries should be removed any time the instrument is placed into
storage. Battery leakage may cause corrosion on the battery contacts, which
must be scraped off and/or washed using a paste solution made from
baking soda and water. Use a spanner wrench to unscrew the battery contact
insulators, exposing the internal contacts and battery springs. Removal of the
handle will facilitate access to these contacts.
