Operating instructions METTLER TOLEDO AM/PM Balances ; _ 0.0 000 9 ;_ 0.0 ;_ 0.
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.

Preparation Select the proper location For best results choose a suitable location for your balance. A firm, vibration-free location as horizontal as possible Avoid exposure to direct sunlight No extreme temperature changes 30° 20° 10° 0° No draft Despite a possible unfavorable location, your balance can still produce accurate weighing results: In this case you should adjust the vibration adapter accordingly. For procedures refer to section «Menu».
Mount the weighing pan / platform PM balances with weighing pan Place pan support 11 and weighing pan 10 on tapered pin 17; connect power cable 20. 10 11 20 17 0.0 0 9 10 20 11 40 0.0 0 PM balances with weighing platform Install platform support 11 with the four pins resting on the four rubber grommets 40; then position weighing platform 10 on platform support 11; connect power cable 20. 9 AM balances: see page 7.
Preparation 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. PM balances with 1 mg readability Mounting procedures 1 and 2 are needed only if the bottom element 12 has not been installed at the factory. 1 Remove weighing pan 10 and pan support 11. Place bottom element 12 on balance, and rotate to stop. Replace pan support 11 and weighing pan 10.
AM balances Mount glass draft shield 13 on scale rotated by 45°. Note that tapered pin 17 must be visible through bottom hole 27. Now rotate glass draft shield clockwise to stop. 1 Verify that the draft shield is aligned parallel to the balance and is properly engaged in bayonet base. 2 Install ring 25 and weighing pan 10, close sliding door 26. Note: Ring 25 protects the weighing pan from lateral impacts.

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.

Operation Simple operation with a control bar 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 these symbols… …You will find them throughout the operating instructions and short-form instructions.
Introducing the symbols Try to familiarize yourself with the key symbols with the aid of the following example. Switch on the display and remove weight from weighing pan. Now try to select and change the weighing process adapter 31b. -.-.-.-.0.0.0 9 Press control bar… 15-cal. . …keep depressed… 31b …release! briefly press control bar! Note: If the display automatically returns to zero (weighing mode) 3 seconds after the control bar was last pressed, simply begin the procedure again.
Menu A clear Menu We distinguish between two levels of software. The first, simpler level, we call the Menu. It can be activated by pressing and holding the control bar. The second software level is called the Configuration file. Details can be found in section «Configuring». When the Menu is activated, you can… 15-cal. . …calibrate your balance, …use the weighing process adapter to set the weighing modes or the weighing sample, and 0.
-cal- 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). Caution: To obtain accurate results we recomment that you connect the balance to the line 30 min before calibrating (60 min for AM balances). 0.00 -.-.-.-.0.0.0 9 Start calibration with display switched on by pressing and holding the control bar (weighing mode, display zero with empty weighing pan). 9 15-cal. .
Menu Adapt your balance to the type of weighing (Weighing process adapter)… Access -.-.-.-.0.0.0 9 Weighing mode 15-cal. . 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.
…as well as to the ambient conditions (Vibration adapter) Access -.-.-.-.0.0.0 9 Weighing mode 15-cal. . Under vibration-free conditions adjust the adapter to obtain results within the shortest possible time. However, if you are operating in an environment with severe vibrations or drafts, adjust the adapter to obtain reliable results, even under adverse conditions.
Configuring 18 Special requirements need special settings within the configuration file Your balance has been factory-set to a standard configuration, i.e. the settings in the configuration file correspond to the most common user requirements. If you wish to change these settings to meet special requirements you must access the configuration file and change the settings according to your needs.

Configuring 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. 1 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.
In the aperture of the program cassette 2, the shorting jumper 24 is now visible. It can be lifted off from the contact pins (e.g. with a small pencil). 4 not secured To protect your settings in the configuration file from involuntary changes, position the jumper across both contact pins (position secured). secured 5 Reinsert the program cassette 2. Ensure that you push it in firmly right to the stop. Then press on the protective cover 3. Connect power cable 20.
Applications Standard applications at a keystroke Counting in or out of a container, percent formula weighing of powders or liquids, plus/minus checks of fill quantities, weighing in grams or in a second, selectable unit, or even animal weighing: all this and more can be performed with the applications built in as standard.
