Section 3 Installation
C A U T I O N
Multiple hazards. Only qualified personnel must conduct the
tasks described in this section of the document.
3.1 Install the battery
W A R N I N G
Explosion hazard. An expired battery can cause hydrogen
gas buildup inside the instrument. Replace the battery
before it expires. Do not store the instrument for long
periods with a battery installed.
W A R N I N G
Potential fire hazard. Use only alkaline or nickel metal hydride batteries
(NiMH) in the meter. Other battery types or incorrect installation can
cause a fire. Never mix battery types in the meter.
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.
