3 Design and Function

3.1 Function description

The QS3 sample changer can be used in conjunction with the Q3 dosing module and can be installed on any

XPR analytical balance. It contains 30 dosing positions (15 when used with sample vessels of diameter

larger than 31.5mm), and therefore provides increased throughput of your dosing activities. The sample

changer can be used to dose liquids as well as powders. The dosing positions are covered by a tunnel draft

shield with two handles, on the right and left side of the weighing chamber. The top door of the balance is

replaced by a top panel especially designed to reduce the influence of air drafts on the weighing results.

Various adapter are available to accommodate a high variety of sample vessels. The vessels with adapters are

placed on the racks, which are in turn installed on the rotating drive ring. Each dosing position is numbered for

easy traceability. When dosing starts, the drive ring rotates and the dosing positions are brought one-by-one

over the weighing pan for dosing.

Simple weighings, adjustments, and tests can still be performed when the sample changer is installed. To this

purpose, a weighing pan cover and a weighing basket are provided with the instrument.

3.2 Overview

See the section "Overview" (graphics and legend) at the very beginning of this manual.

6 QS3 Sample Changer

3.3 Components description

Weighing pan and rail

A rail is fixed to the base ring. All adapters and sample

vessels slide on this rail as the drive ring rotates. The rail has

one gap above the weighing pan. When a sample vessel

reaches this position, its weight hangs on the weighing pan,

allowing weighing/dosing.

Drive ring

The drive ring is the rotating component of the sample

changer. It contains six elongated slots to fit six racks, each

with five dosing positions. The drive ring also presents a

single round hole, the Home position, where simple

weighing, adjustments, and tests can be performed. When

the Home position is not used for weighing, cover the hole

using the Home position cover.

The rotation of the drive ring is provided by a motor and a

driving wheel, located at the rear of the sample changer.

Racks for sample vessels

The racks are used to hold the adapters (each containing a

sample vessel). Up to six racks can fit on the sample

changer, each with five dosing positions. Each position is

numbered to allow dosing traceability.

en

7QS3 Sample Changer

Home position cover

The Home position cover is designed to avoid unwanted

powder on the weighing pan. Whenever possible, cover the

hole of the Home position with the Home position cover.

Weighing pan cover

When performing a simple weighing, adjustment, or test, you

can use the weighing pan cover in the Home position.

If the drive ring rotates while the weighing pan cover or the

weighing basket is installed, the sample changer or the load

cell could be damaged. Always remove the weighing pan

cover or the weighing basket as soon as the operation is

completed. Place back the Home position cover.

Weighing basket

When using small weights that need to be positioned

precisely in the middle of the weighing pan, use the weighing

basket in the Home position.

If the drive ring rotates while the weighing pan cover or the

weighing basket is installed, the sample changer or the load

cell could be damaged. Always remove the weighing pan

cover or the weighing basket as soon as the operation is

completed. Place back the Home position cover.

8 QS3 Sample Changer

Tunnel

To minimize the influence of air draft on the weighing, a

tunnel is enclosing the weighing chamber and the drive ring

holding the racks and sample vessels. The racks can be

accessed by simply sliding tunnel on the right or left side of

the weighing chamber.

Top panel

The top panel of the QS3 sample changer is designed to

minimize the air draft in the weighing chamber.

4 Installation and Putting into Operation

This instrument must be installed by a METTLER TOLEDO service technician.

The QS3 sample changer is compatible with all XPR analytical balances with tall draft shield.

4.1 Selecting the location
