Periodic service
WARNING!
Repair and service of this instrument is to be performed by qualified
personnel only. Improper repair or service could result in physical
degradation of the meter. This could alter the protection from
electrical shock and personal injury this meter provides to the
operator. Perform only those maintenance tasks that you are
qualified to do.
These guidelines will help you attain long and reliable service from
your meter:
1. Calibrate your meter annually to ensure it meets original
performance specifications.
2. Keep your meter dry. If it gets wet, wipe it dry immediately. Liquids
damage electronic circuits.
3. Whenever pra c t i cal, keep the meter away from dust and dirt, which
can cause premature wear.
4. Although your meter is built to withstand the rigors of daily use, it
can be damaged by severe impacts. Use reasonable caution when
using and storing the meter.
Cleaning and Decontamination
Periodically clean your meter’s case using a damp cloth. DO NOT use
abrasives, cleaning solvents or strong detergents, as they may damage
the finish or affect the reliability of the structural components.
Battery and Fuse Replacement
If “ “ appears on display, it indicates that the battery should be
replaced. Always use a fresh replacement battery of the specified size
and type. Immediately remove the old or weak battery from the meter
and dispose of it in accordance with your local disposal regulations. Old
or defective batteries can leak chemicals that corrode electronic circuits.
To replace battery and fuse (200mA/250V) remove the 2 screws in the
bottom of the case. Simply remove the old, and replace with a new one.
WARNING!
To avoid electric shock, be sure to turn off the meter’s power and
disconnect both test leads from any equipment before you remove
or install batteries.
