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.
The meter can be powered with AA alkaline or rechargeable NiMH
batteries. To conserve battery life, the meter will power off after
10 minutes of inactivity, the backlight powers off after 30 seconds. This
time can be changed in the Power Management menu.
Note: Rechargeable batteries will only be recharged with the USB/power module.
Refer to the module documentation for further information.
For battery installation refer to Figure
