4.0 User Maintenance – Recommended Cleaning Procedures
4.1 Cleaning the Probe and the Datum Disks
IT IS IMPERATIVE THAT BOTH THE PROBE FACE AND FASTENER DATUM DISK SURFACE
BE KEPT CLEAN AND DRY FOR ACCURATE MEASUREMENT OF LOAD. UNDER NO
CIRCUMSTANCES SHOULD THE PROBE FACE OR THE DATUM DISK SURFACE BE CLEANED
BY ABRADING WITH EMERY CLOTH OR SANDPAPER.
Cleaning of the probe face should only consist of wiping with a lint-free, dry cotton cloth followed by
forced, moisture-free, air cleaning. An example of a clean and dirty probe face is shown in
Figure 4.3.1
.
The following cleaning recommendations are made in the event that incidental soiling of the datum disk
surface does occur.
(1)
In most cases, light soiling of the datum disk surface such as moisture, dust, dirt, oil, metal chips, etc., can
be cleaned by wiping with a lint-free, dry cotton cloth followed by forced moisture free, air cleaning. The
forced air stream can be compressed air delivered through an air nozzle, or a can of compressed air
commonly used in cleaning electronic components and computer equipment.
(2)
For cleaning oil or grease from the datum disk, soaking the cloth with a solvent such as alcohol or acetone
may be required for thorough cleaning. The use of an aerosol can containing automotive brake fluid has
been proven successful in cleaning these contaminants. However, it must be a fast-drying formula and one
that leaves no residue.
(3)
In the event that light rusting of the datum disk surface occurs, light brushing with the supplied brass bristle
brush should precede the cleaning procedure described above.
