described in this section of the document.
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.
The meter can be powered with AA alkaline or rechargeable NiMH
batteries. To conserve battery life, the meter will power off after
5 minutes of inactivity. This time can be changed in the Display Options
menu.
