Precautionary labels
Read all labels and tags attached to the instrument. Personal injury or
damage to the instrument could occur if not observed. A symbol, if noted
on the instrument, will be included with a danger or caution statement in
the manual.
This symbol, if noted on the instrument, references the instruction
manual for operation and/or safety information.
Electrical equipment marked with this symbol may not be disposed of
in European public disposal systems after 12 August of 2005. In
conformity with European local and national regulations (EU Directive
2002/98/EC), European electrical equipment users must now return old
or end-of-life equipment to the Producer for disposal at no charge to
the user.
Note: For return for recycling, please contact the equipment producer or supplier
for instructions on how to return end-of-life equipment, producer-supplied electrical
accessories, and all auxillary items for proper disposal.

Installation
C A U T I O N
Personal injury hazard. Only qualified personnel should conduct the tasks
described in this section of the manual.
Install the batteries
W A R N I N G
Explosion hazard. Incorrect battery installation can cause the release of explosive
gases. Be sure that the batteries are of the same approved chemical type and are
inserted in the correct orientation. Do not mix new and used batteries.
N O T I C E
The battery compartment is not waterproof. If the battery compartment becomes
wet, remove and dry the batteries and dry the interior of the compartment. Check
the battery contacts for corrosion and clean them if necessary.
N O T I C E
When using nickel metal hydride (NiMH) batteries, the battery icon will not indicate
a full charge after freshly charged batteries have been inserted (NiMH batteries
are 1.2 V versus 1.5 V for alkaline batteries). Even though the icon does not indicate
complete charge, 2300 mAH NiMH batteries will achieve 90% of instrument
operation lifetime (before recharge) versus new alkaline batteries.
N O T I C E
To avoid potential damage to the meter from battery leakage, remove the meter
batteries prior to extended periods of non-use.
