BATTERY OPERATION
•
The scale can be operated from the battery if desired. The battery life can be
up to 70 hours depending on the load cells and how the backlight is used.
•
A battery symbol is shown on the display which indicates the current charge of
the battery, 3 bars means fully charged. When just the outline of the battery and
no bars are visible the battery needs to be re charged.
•
To charge the battery, simply plug the adaptor into the mains power, and also
into the input connector on the rear of the Indicator marked DC 12V. The scale
does not need to be turned on.
•
The battery should be charged for 12 hours to reach full capacity.
•
Near the display 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.
