Appendix A-8
Replacing the Protective Cover
The gauge includes a replaceable, adhesive-backed bottom
cover disc that protects the bottom surface of the gauge’s
sensor assembly against wear and provides thermal
protection for the gauge’s internal components. The
protective cover disc adheres to the rear base assembly. When
the disc becomes worn, it should be replaced as described
below.
NOTE
Additional bottom cover discs can be purchased from
Troxler by ordering PN 113103, Cover Replacement Kit,
which includes three discs.
To remove the old protective cover disc:
1. Turn the gauge over so that its bottom surface is exposed.
To prevent damage to the keypad or display, place the
gauge on a soft surface.
2. Using a knife or other flat object, gently lift the edge of
the disc. After loosening, peel the cover off by hand.
To install the replacement protective cover disc:
1. Clean the surface of the sensor with alcohol (used
sparingly) and allow the surface to dry.
2. Peel the adhesive backing from the replacement
protective cover disc.
CAUTION
To prevent damage to the gauge, DO NOT operate the
gauge without the protective cover disc.
