2.5.2 Battery Power
The battery will begin charging with the AC adapter connected
accordingly. An LED indicator below and to the left of the scale shows the
status of battery charging:
●
Green-battery is fully charged
●
Yellow-battery is partially charged and charging
●
Red -battery is nearly discharged
When AC power is not available, the scale will operate on the internal
rechargeable battery. The scale will automatically switch to battery
operation if there is a power failure or the power cord is removed. Low
battery charge is indicated by the annunciator.
Before using the scale for the first time, the internal rechargeable battery
should be fully charged for up to 12 hours. A fully charged battery can
operate the scale for approximately 80 hours independent of AC power.
The battery is protected against overcharging and the scale can remain
connected to the AC power line.
NOTE:
●
The battery must be recharged every 3 months if the scale is not
used for a long time.
●
Dispose of the lead acid battery according to local laws and
regulations.
2.6 Initial Calibration
When the scale is operated for the first time, a Span Calibration is
recommended to ensure accurate weighing results. Before performing
the calibration, be sure to have the appropriate calibration weights.
Refer to Section 5.1 for Span Calibration procedures and Section 6 for
AUTO CALIBRATION.
