REQUIREMENTS FOR AN OPTIMAL INSTALLATION

To obtain the maximum performance and the best results, we recommend
installing the balance according to the following requirements:

• Install it on a firm and stable surface.

• Place it on a stable base free of vibrations.

• Don´t expose it to direct sunlight.

• Don´t submit it to atmospheres with corrosive gases.

• Keep it in an environment free of dust and dirt.

• Work at temperatures between 0º and 40º C.

• Use the balance in environments with humidity lower than 95% HR.

• Keep the balance away equipments that produce magnetic oracoustic
interferences.

• Calibrate it in its definitive location and check it regularly with the
optional calibration weight. If necessary, recalibrate it.

COMPONENTS INCLUDED

Unpack the balance carefully. Inside the carton you will find the following
components:

• This user manual (please read it before using the balance).

• A AC/Adaptor 9V / 500 mA or 700mA.

6

• A balance Series AM.

• A transparent dust cover.

• A weighing pan.

VERY IMPORTANT: Keep the original package. It could be useful in the future
in transporting the balance.

UNPACKING

1. Remove the weighing pan from the package.

2. Remove the balance and place it on a flat, firm and stable surface.

3. Install the weighing pan, so that the four platter screws fit in the top
holes of the balance.

INSTALLATION

1. Level the balance by turning the four adjustable feet, the bubble level
located on rear side of the balance must remain in the centre of circle.

2. Connect the balance to the supplied AC/Adaptor 220 V 50.

connected for about 10 minutes before using it. However, the balance
can be used immediately with good results.

DISPLAY DESCRIPTION

1. Indicates that the balance is in zero point, if the function tare is not

in use.

2. Shows the weight of item located on the weighing platter.
