INSTALLATION INSTRUCTIONS

 Remove balance and accessories from the carton.

 Do not install the balance in a place with draughts, heavy thermic changes and

vibrations.

 Place the weighing pan and the support pan on the balance (see page 4-5).

 Level the balance using the level bubble and levelling feet located underneath the

case (see page 7-8 fig. 1a/1b).

 Connect power supply to connector 2 located on the rear panel of the unit (see page

7-8).

 Insert power cord into AC outlet, which shall be easily accessible; after few

seconds the balance will automatically switch on.

 Wait 30 minutes from switch on and calibrate the balance using the mass enclosed

in the package, following the instructions (page 10).

 Calibrate the balance again every time it is removed from previous place.

 Check balance calibration periodically.

 We recommend not to drop heavy objects on balance pan, in order to avoid

damages.

 Assistance service must be effected by specialized staff and the spare parts used

must be original.

Therefore, it is necessary to apply to the seller who sold the equipment.

 Keep package in case the balance should be sent back to the factory for service.

EXTERNAL CALIBRATION *

* (For all models except Analytical
balance).

The electronic reading balance takes
measurement of mass making use of

glb ctoz

gravity (g). Difference in geographic area
and altitude will vary gravity acceleration
(g). Therefore, for accurate measurement,

scale must be adjusted to the local
environment. This adjustment is
accomplished by CAL key.

At empty pan, press CAL key.
Dashes are displayed.

than the one set.
To perform this sort of calibration,press

Now load on the pan a weight equal or
higher than calibration weight set; the
balance will recognise as valid a weight
equal or higher than calibrationweight as
long as it is a whole number in
comparison with the most meaningful

digit of calibration weight..
Example: if calibration weight is 200g, it
will be possible to calibrate the balance
with values from 200g,300g,400g up to
the highest limit of balance weighing
range.
The message"LOAD" on display will

Once calibration has been effected, the
