above.
In all cases the scale must return to zero or a negative number
before another sample can be added to the memory.
More product can then be added and PRINT pressed again. This
can continue for up to 99 entries, or until the capacity weight display is
exceeded.
4. BATTERY OPERATION
The scales can be operated from the battery if desired. The battery
life is approximately 90 hours.
When the battery needs charging the arrow above the low battery
symbol under the weight display will turn on. The battery should be
charged as soon as the arrow above the symbol is on. The scale will still
operate for about 10 hours after which it will automatically switch off to
protect the battery.
To charge the battery simply plug into the mains power. The scale
does not need to be turned on.
The battery should be charged for 12 hours for full capacity.
Just under the display (CTG) is an LED to indicate the status of
battery charging. When the scale is plugged into the mains power
the internal battery will be charged. If the LED is green the battery
has a full charge. If it is Red the battery is nearly discharged and
yellow indicates the battery is being charged.
As the battery is used it may fail to hold a full charge. If the battery
life becomes unacceptable then contact your distributor.
5. CALIBRATION
To start calibration turn the scale off and then turn it back on. Press
the Tare and % keys together during the initial counting from 9 to 0 on the
