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 thoroughly 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, 2500 mAH NiMH batteries will achieve 90% of instrument
operation lifetime (before recharge) versus new alkaline batteries.
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.
