Thank you very much for the confidence you have shown in our products by choosing a METTLER TOLEDO precision or analytical balance. To obtain complete satisfaction from your balance, it is essential that you read through these operating instructions carefully.
These operating instructions apply to balances of the AM and PM series with a weighing range up to 6 kg. Although the operating procedures for these balances are identical, differences exist regarding the weighing range, the readability accuracy and the weighing pan or platform.
Enclosed with these operating instructions is the booklet «Technical data and accessories», which also contains possibilities of the METTLER
TOLEDO AM/PM balances.

Don't forget to install the draft shield
To ensure that the weighing results are not influenced by the drafts (particularly for sensitive measuring ranges) we recommend the installation of a draft shield.

The METTLER DeltaTrac
This dynamic graphic indicator with 60 radial segments is incorporated in all balance models. METTLER DeltaTrac shows you a graphic representation of the numerical values shown in the digital display.
With absolute weighing, subtractive weighing, weighing-in and formula weighing, the dynamic display indicates the weighing
range used up and that still remaining.
With the aid of METTLER DeltaTrac you can check fill quantities and determine deviations from a definable target weight in percent.
You can always see the tolerance limits with correct signs, as well as positive or negative deviations (see «Applications»).
When used together with METTLER TOLEDO Pacs, the METTLER DeltaTrac can also perform additional functions (see booklet «Technical data and accessories»).

Switching on/off, calibrating, configuring: All of these operations can be initiated with the control bar. You can even use this single control bar to activate the applications incorporated as standard.
For more convenient operation of the applications, the GM303 Terminal (direct function, switch and print key) from the accessories can be used.

Note: If you have selected the menu step «Weighing process adapter» or «Vibration adapter» and do not press the control bar for 3 seconds, your balance will return automatically to the weighing mode. However, the actual settings are stored (the same applies if you return to the weighing mode by pressing and holding the control bar).

Calibrate your balance
Before the balance is used for the first time, it must be calibrated (to take the acceleration due to gravity into account).

Weighing mode
With this adapter you will optimize the display speed of the last digits as a function of weighing mode: For instance, for fine dispensing of powders even the last place of the digital display must be continuously recognizable. This is not the case for absolute weighing; the weighing process adapter thus suppresses the display during the weighing process. The result with all decimal places will appear only when it is stable.
Weighing process adapter
Weighing process
Fine dispensing (weighing-in) of fine powder or small quantities of liquids
Remarks
For slow filling-in of weighing goods all decimal places of the display are available. The weight increase can thus be followed easier.
Universal
Absolute weighing
Standard setting. With DeltaDisplay –on– , the last decimal place is suppressed in coarse dispensing, see page 25.
In this setting, you can rapidly check a weight. Only the final result appears in the display. «------» is displayed during the unstable phase.
Animal weighing
Your balance is now operating in the animal weighing mode, e.g.
movements of a live animal do not influence the display. The measurement values are averaged during a certain time period and subsequently indicated on the display.
Starting of measuring cycles and setting of measuring time are explained in section «Applications, animal weighing».

Only stable values are transferred after every change of weight (necessary change 1 g. Exceptions: PM6: 5 g and AM50/AM100: 0.2 g. For animal weighing see section «Applications»).
All values (dynamic «SD» and stable «S») are transferred automatically.

The baud rate is the transfer rate unit for serial data transmission in bit/sec:

Caution: For handshake mode operation the transfer input may not be used.
Certification symbol in data transmission
If balances are connected to peripheral units that can not process the certification symbol ( <…>, * ) (e.g.LP16-M

How to protect the new settings in the configuration file
After having completed your configuration, you can protect your settings against inadvertent changes. Proceed as follows:
To protect the program cassette from possible interface, it is absolutely essential to first disconnect the line cable 20.

Now remove cover 3, for instance with a screwdriver. The program cassette is now visible.
2
Grasp bracket of program cassette 2, and carefully pull out cassette.

Print/transfer command can be initiated with the control bar.
%
Plus/minus and percent weighing
The balance can also be used for plus/ minus checks. If your balance is used for checks in %, the METTLER DeltaTrac indicates the deviation from the preset target weight, the tolerance limits of +/-
2,5 % and their violations. You can of course perform the usual percent weighings simply and rapidly.

• Set data transfer mode «S» to –Auto–
(see also «Configuration, Sector –I-Face–»). Placing a live animal on the weighing pan automatically initiates a weighing cycle.
To initiate a new weighing sequence, the load on the balance between two animal weighings must be reduced to less than 2 g for
0.1 mg balances, 10 g for 0.1 mg/10 mg and 100 mg balances,
50 g for g-balances.

Carefully lower upper section of housing 22 vertically onto the balance.
Replace screw 21 and tighten, place pan/platform support on tapered pin 17 or the four rubber grommets 40. Finally, place the weighing pan or platform 10 on its support 11 and connect power cable 20.

Position balance on its side. Remove control bar 1 by applying pressure toward A. It will disengage and can be lifted off in the direction of B.
Remove protective cover 16.

Before mounting the new protective cover 16, the two protective foils must be removed at the adhesion points. Next, to attach the new protective cover 16 at rear of balance and press down in front. Briefly press the two adhesive spots 41 against upper section of housing.
Slide on control bar 1, replace platform support 11 and weighing platform 10.
Easy to clean
For cleaning the stainless steel pan, a cloth with soap and water is adequate. Never use powerful solvents.
