exceed 10 seconds continuously.
MAINTENANCE AND REPAIR
If there appears to be a malfunction during the operation of the meter, the following steps should
be performed in order to isolate the cause of the problem.
1. Check the battery. Replace the battery immediately when the symbol "N" appears on the
LCD.
2. Review the operating instructions for possible mistakes in operating procedure.
Except for the replacement of the battery, repair of the meter should be performed only by a
Factory Authorized Service Center or by other qualified instrument service personnel. 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. Do not use aromatic hydrocarbons, Gasoline or
chlorinated solvents for cleaning.
• Periodically wipe the case with a damp cloth and mild detergent. Do not use abrasives or
solvents.
• To clean the terminals with cotton bar with detergent, as dirt or moisture in the terminals
can affect readings.
