4.2 Selecting the location
A good location will enable the balance to work accurately and reliably. The surface must be able to safely take the weight of the balance when fully loaded. The following local conditions must be observed:
If the balance is not horizontal at the outset, it must be leveled during commissioning.
• Operate the balance in indoor environments only and at an altitude of less than 4000 m above sea level.
• Before switching on the balance, leave the parts to reach room temperature (+5 to 40°C).
Ensure that the relative humidity is between 10% and 80% and non-condensing conditions are met.
•
•
•
•
•
•
•
The power plug must be easily accessible.
No powerful vibrations
No direct sunlight
No excessive temperature fluctuations.
No powerful drafts.
No powerful electric or magnetic fields
Ensure that the surroundings as free from dust as possible.
4.3 Unpacking
Open the balance packaging. Check the balance for transport damage. Immediately inform a METTLER TOLEDO representative in the event of complaints or missing accessories.
Retain all parts of the packaging. This packaging offers the best possible protection for transporting the balance.

4.6.2 Leveling the balance
Exact horizontal and stable positioning are essential for repeatable and accurate weighing results.
The balance can be levelled using the leveling assistant and/or the level indicator on top of the terminal. There are two adjustable leveling feet to compensate for slight irregularities in the surface of the weighing bench.
The balance must be leveled and adjusted each time it is moved to a new location.
4.6.2.1 Leveling the balance using the level indicator
All balances have a level indicator with an air bubble that can be used level the balance manually.
Leveling balances with a readability of 0.1 mg and 1 mg

Autoincrement
Input prompt
Autoincrement
The function Autoincrement specifies that the last part of the ID is incremented with each use of that ID. There are two basic functions depending on how the ID is defined:
• If there is no counter in the ID, the system automatically adds a counter to the ID starting with 1 (e.g. the ID
Process will be Process1 in the next use).
•
•
•
If a counter is part of the ID, the system automatically increments the ID starting at that counter (e.g. the ID
Process 1 will be Process 2 in the next use).
The counter must be set at the end of the ID, otherwise the system doesn't recognize the number as a counter (e.g. in 567Apple the system doesn't recognize 567 as a counter).
If the ID has no counter and a maximum length of 16 characters, the last few characters will be overwritten by the counter.
Input prompt
The Input prompt function can be used for every ID. If Input prompt is activated, the ID will be prompted on the display before it is used. The user can decide whether to use the default value that has been defined with the ID or define an individual value.

Counting with reference weight check
The reference weight check ensures that the reference weight is high enough for the resulting counting accuracy to fit the customer process tolerance. Activate a reference weight check and define the process tolerance in percent. The percentage factor range is 0.01 - 30.00%. The higher the factor, the smaller the required minimum reference weight. Factory setting: 2%. The minimum reference weight is equal to d / factor.
Precision and Analytical Balances Activities 55
Example d = 0.1 g
Factor = 20%
Minimum reference weight = 0.1 g / 20% = 0.5 g
If the reference calculation is activated manually or automatically, the minimum reference weight is checked to ensure the desired accuracy. If it is not sufficient, the user is prompted to add the number of additional parts needed. The number of additional parts needed is reduced to zero, after which the user adds additional parts. At zero, the reference calculation is activated automatically. If too many parts are added, the user is prompted to remove the number of parts until zero is reached.

7.1.9 Differential weighing
Navigation: Activities > Activities - Weighing and other applications > Differential weighing
For differential weighing, one or several samples are checked for weight variations. The first step consists of determining the initial weight of the sample (initial weighing). Certain sample components are subsequently removed or added. Processes, e.g. drying, filtering, evaporation and coating, are also possible. After processing, the sample is weighed again (back-weighing). The balance subsequently determines the difference between the two values.
The principle function of the differential weighing application is very similar to the one of back-weighing.
However, back-weighing is designed for a very basic work flow with one sample only and very few configuration options. The differential weighing application offers much more flexibility, with up to 200 samples and different workflow options, but it is also more complex to configure and use.
The statistics function can be activated; information on this topic can be found in the chapter

There are two different weighing sequence options for differential weighing that are supported by the differential weighing application. For each weighing sequence option (work flow), a maximal version with all options activated and a basic version are described as a sample. Additionally, the user can deviate anytime from the given sequence by choosing the required sample in a list on the balance or identifying the sample ID by a barcode reader (please refer to chapter [Workflow - Free navigation } Page 81]).

7.1.9.1.3 Workflow - Free navigation
Regardless of which weighing sequence option is chosen ( Sample by sample or Initial weighings first
(Default) ), the default workflow can be interrupted and each sample and weighing process can be performed in a sequence according the user's requirements. The required sample can be selected either by navigating to the result table via the work title bar or swiping from sample to sample on the work title bar. Especially convenient is to identify the sample before the back-weighing by scanning its ID with a barcode reader. The balance does then automatically show the correct sample to proceed with the weighing process.

7.1.10 Density
Navigation: Activities > Activities - Weighing and other applications > Density
Density allows the density of solid bodies and liquids to be determined.
The density is determined via the Archimedes principle, according to which a body immersed in a fluid undergoes an apparent loss in weight which is equal to the weight of the fluid it displaces.
To determine the density of solid bodies, we recommend using the optional density kit, which contains all attachments and aids needed for convenient and precise density determination. To determine the density of liquids, a sinker is also required. This can be obtained from your METTLER TOLEDO dealer.
The statistics function can be activated; information on this topic can be found in the chapter

11.4.4 MT-SICS interface commands and functions
Many of the instruments and balances used have to be able to integrate into a complex computer or data acquisition system.
To easily integrate a balance into a system and utilize its capacity to the full extent, most balance functions are also available as corresponding commands via the data interface.
All new METTLER TOLEDO balances launched on the market support "METTLER TOLEDO Standard Interface
Command Set" (MT-SICS). The commands available depend on the functionality of the balance.
For further information, please contact your METTLER TOLEDO representative.
Refer to the MT-SICS Reference Manual which can be downloaded from the Internet at u www.mt.com/library
