Maintenance
In case you do not obtain the expected measurement result:
1. Check the batteries.
2. Review the operating instructions for possible mistakes in
operating procedure.
3. Inspect the thermocouple probe for a broken or intermittent
connection.
Except for the replacement of the batteries, repair of the
thermometer should be performed only by the Factory or by a
Factory Authorized Service Center.
The front panel and case can be cleaned with a mild solution
of detergent and water. Apply sparingly with a soft cloth and
allow to dry completely before using.
