Maintenance
Instrument maintenance consists of keeping the instrument clean and
periodically checking the batteries and the calibration. The Model 3-IS
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 1 minute before accessing internal
components.
Recalibration
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 detector 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
manufacturer’s instruments. Calibration procedures are available upon request
for customers who choose to calibrate their own instruments.
Batteries
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.
