7. MAINTENANCE PROCEDURES
7.1 INTRODUCTION
Routine maintenance of the instruments consists of
external care only. Except for the batteries, there are no
user serviceable parts inside the instrument. Opening the
instrument voids the warranty.
This section provides details of the recommended preventive
maintenance, advice on battery maintenance and lists some
simple checks that can be carried out if operational problems
are experienced.
7.2 PREVENTIVE MAINTENANCE
(1) Ensure that the battery end cap is fully screwed into
position.
(2) Ensure that the exterior of the instrument is clean, dry
and free of corrosive contaminants. If necessary, wipe
with a cloth moistened with a mild detergent. Allow to
dry before using the instrument.
(3) Ensure that the batteries are kept in a useable
condition.
7.3 BATTERY MAINTENANCE
7.3.1 Dry Cell Batteries
(1) When the battery warning symbol is shown on the
instrument display, switch off and replace all three dry
cell batteries.
This symbol indicates that there is at least 15
minutes use remaining. For a more precise
estimation, refer to the
Instrument Info
option of
the Main Menu (see Section 2.2.3).
