BATTERIES
The 3440 gauge constantly updates the battery condition. Depending on
operator preference, either the hours remaining or the battery voltage will
be displayed. A fully charged battery will last approximately eight weeks
under normal working conditions (eight-hour days) before recharging is
necessary.
A low battery condition is indicated by the following display:
When this display appears, the battery must be recharged within a few
hours. For best results, perform a full recharge with the ac charger. To
access the charger port, unscrew the two captive screws that attach the
black access cover to the front panel. Plug the charger into the round plug
under the access cover. Plug the other end of the charger into a standard
110 V ac wall outlet. For a full charge, recharge the gauge for at least
sixteen hours.
If necessary, for emergency use, a 30-minute recharge with the dc or ac
charger provides several hours of use. After a short recharge time, the
battery life display may not always indicate an accurate update of the
battery-life. Only a full sixteen-hour recharge will reset the battery life
indicator.
NOTE
For more information on updating or resetting the battery
monitor, refer to page 6–27.
Although batteries cannot be “overcharged”, rechargeable batteries have a
memory and repeated needless charging will shorten the battery life. Do
not recharge batteries unless the battery indicator signals a low battery.
ALKALINE BATTERY USE
If recharging is not an option, alkaline batteries may be used. An accessory
battery case assembly (PN 104148) is available as an option.
