Notes:
Battery packs are fully protected against
overcharge and over-discharge. Charge life is updated every 1.9
seconds and is indicated under the SETUP menu. Full NiMH recharge
shall be made within 3 hours by means of a 110/220 V ac, 50-60
Hz charger. Recharging shall also be accomplished by a 12-14 V dc
charger.
A fully charged battery will remain operational for approximately
3 weeks (of standard use) without the GPS option (available only
on the Model 3440 Plus) or use of backlight options. These options
will reduce the battery life when utilized. The alkaline backup
batteries will add an additional 1.5 weeks when the GPS and backlight
features are not operating.
The gauge can store up to 999 test readings for later recall or
downloading to a printer or computer. The Model 3440 Plus gauge
also allows for data transfer via a USB port utilizing a USB printer
or a removable drive. A list of compatible USB devices is available
here.
