General Power Supply; Battery Power Supply; Mains Connection During Rechargeable Battery Operation; Battery Exchange - G&G EY Series Operating Instruction

1. Take the balance and supplied accessories (a feeder, pan elements) out of the box.
2. Place the balance on a stable ground not affected by mechanical vibrations and airflows.
3. Level the balance with foot screws so that the air bubble in water-level is in the middle.
4. Plug the adapter to the power socket at the back of the balance.
5. Connect the power adapter to an AC220V ± 10%, 50Hz/60Hz outlet.

6.3 General power supply

If the balance is used in a laboratory, it can be powered by the external mains adapter (included). In case
the balance is used as a mobile weighing instrument, it can be powered by AA batteries (not included) or
internal accumulator (included). The accumulator is charged via the delivered adapter.
To extant work time of accumulators (battery), it is possible to turn off display's backlight and the balance
automatically. The settings of "Power Save" operation see chap. 9.3 and chap. 11.
Please only use the original supplied mains adapter. Otherwise there is a risk that the Balance be
impaired.
If the balance is not used for a long time, remove the battery/accumulator and store them separately.
Leaking battery liquid could damage the balance.

6.3.1 Battery power supply

The balances can be supply from mains power witch is delivered with the balance. It is also possible to use
normal AA batteries.

6.3.2 Mains connection during rechargeable battery operation

When the balance is connected with the mains adapter, the battery power will be disconnected
automatically. Therefore, there is no battery charging function under the battery power supply.

6.3.3 Battery exchange

Remove the battery compartment cover and insert six batteries (AA size) into the battery compartment,
taking extreme care that the polarities plus (+) and minus (-) is observed.

6.4 Initial Commissioning

In order to obtain exact results with the electronic balances, your balance must have reached the
operating temperature (warming up time 30 min.). During this warming up time the balance must be
connected to the power supply (mains, accumulator or battery).
The accuracy of the balance depends on the local acceleration of gravity.
Please read the information carefully in chap.

"Adjustment".

6.5 Adjustment
As the acceleration value due to gravity is not the same at every location on earth, each balance must be
coordinated - in compliance with the underlying physical weighing principle - to the existing acceleration
