the power adaptor as soon as possible to change the battery.
The LED display provides information about the battery's charging status.

7.5 Initial Commissioning
In order to obtain exact results with the electronic balances, your balance must have
reached the operating temperature (see warming up time chap. 1). During this warm-
ing up time the balance must be connected to the power supply (mains, accumulator
or battery).
7.6 Balance zero display
Environmental influences can lead to the exact figure of zero not being displayed in
spite of an empty weighing dish. It is, however, possible to reset your balance to zero
at any time and thus ensure that weighing really does commence at zero. Setting to
zero when a weight is applied is only possible within a certain type-dependent range.
In the event that the balance cannot be reset to zero with an applied weight, this
range has been exceeded (± 0,2 % max).
To reset the balance to zero, press key
. A triangle [W ] pops up next to the [ a ]
symbol on the display.
