4.3.4 CONV Function
Pressing the CONV button causes the 8000 to change the current weight display unit
each time it is pressed.
In the "Std" mode, the weight will convert from "lb" to "kg" to "oz", and also to "lb & oz"
when the scale is set to one of the capacities listed in Section 3.4.5.
In either of the "Legal for Trade" modes ("44" or "CAN"), the "lb & oz" mode is disabled
since NIST and Canadian Weights and Measures do not recognize the "lb & oz" unit as
a Legal for Trade display.
4.3.5 PRINT Function
Pressing the PRINT button causes the Data Interface to transmit displayed weight data
in the configured Print Format. It is active in all of the data output modes except for the
Continuous Transmission mode.
The weight data will be transmitted as long as the scale is stable and not in overrange.
4.4 BATTERY CHARGING (8000M only)
Note: 8000IS users, refer to the 8000IS Manual.
The 8000 is equipped with a self-contained rechargeable, sealed, gelled-electrolyte
battery and charging circuit, both internal. The 8000 is designed to run continuously for
40 hours on a fully charged battery. The charging circuit will fully charge the battery in
approximately four hours. To charge the battery, simply plug the line cord into a
standard 115V (220V optional) wall outlet.
The 8000's charging circuit is a two-stage, current limited type charger. The 8000 will
sense the charge condition of the battery and charge at a high rate when the battery is
depleted. When the battery comes up to a fully charged state, the charger will switch to
a "float" or "trickle" mode which maintains the battery at a fully charged state without
overcharging.
The flashing "BATT" indicator indicates that the battery is in need of recharging. The
8000 will continue to operate accurately for approximately four hours after "BATT"
begins flashing. When the battery is too low to run the scale, the 8000 simply turns off
and will not operate again until the battery is recharged.
At this point, when ON/RESTART is pressed, the "BATT" indicator will flash as the 8000
performs its display test and then the scale will shut down immediately. This eliminates
any potential scale errors.
The 8000 can be used while recharging the battery. A full recharge takes place in four
hours, whether the 8000 is on or off. The 8000 can be used with the AC charger cord
plugged in on a continuous basis.
If an AC power failure occurs, the 8000 battery takes over to provide uninterrupted
scale operation for up to 40 hours.
