Connecting Power

2.5.1 AC Power

Verify that the intended AC power source matches the AC adapter rating. Connect the
supplied AC adapter to the power input receptacle underneath the scale. Plug the AC
adapter into a properly grounded power outlet.

2.5.2 Battery Power

The battery will begin charging with the AC adapter connected accordingly. An LED
indicator below and to the right of the display shows the status of battery charging:
• Green – battery is fully charged
• Yellow – battery is partially charged and charging
• Red
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 low
battery annunciator on the display (the scale will operate for approximately 10 hours
more before automatically switching off).
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 scale can be operated during
the charging process. The battery is protected against overcharging and the scale can
remain connected to the AC power line.
Attention:
• The battery must be recharged every 3 months if the scale is not used
for a long time.
• Replace the battery if it does not charge or hold a full charge.
• Dispose of the lead acid battery according to local laws and regulations.
BATTERY IS TO BE REPLACED ONLY BY AN AUTHORIZED SERVICE
DEALER. RISK OF EXPLOSION CAN OCCUR IF REPLACED WITH THE
WRONG TYPE OR CONNECTED IMPROPERLY.

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 6 for Span Calibration procedures.
