Appendix D: Inspection and Cleaning
Inspect and clean the exterior of the instrument as often as operating conditions
require. Dirt acts as an insulating blanket, preventing efficient heat dissipation.
Regular cleaning may prevent instrument malfunction and enhance reliability.
WARNING. To avoid personal injury, unplug the power cord from line voltage
before cleaning the instrument. To avoid getting moisture inside the instrument
during external cleaning, use only enough liquid to dampen the applicator.
Inspecting the Exterior
Inspect the outside of the instrument for damage, wear, and missing parts, using
Table D--1 as a guide. Instruments that appear to have been dropped or otherwise
abused should be checked thoroughly to verify correct operation and perfor-
mance. Immediately repair defects that could cause personal injury or lead to
further damage to the instrument.
