4.3 Selecting the location

Your balance is a sensitive precision instrument; the location where it is placed will have a profound effect

on the repeatability and accuracy of weighing results. Chose a stable surface that is as horizontal as

possible. The surface must be able to safety carry the weight of a fully loaded balance.

Observe ambient conditions (see Technical Data).

Avoid the following:

• Direct sunlight

• Air drafts (e.g. from fans or air conditioners)

• Temperature fluctuations

• Vibrations
Precision and Analytical Balances Installation and Putting into Operation 21

4.4 Connecting the instrument

The balance is supplied with a country-specific AC/DC adapter or with a country-specific power cable. The

power supply is suitable for all line voltages in the range: 100 - 240 VAC, 50/60 Hz. For detailed specifications, see the section Technical Data.

CAUTION 

Allow the balance to warm up for 30 minutes (0.1 mg models need 60 minutes) to adapt itself to the

ambient conditions.

Connect the AC/DC adapter to the connection socket on the back of your

balance and to the power line.

Attention

• Check if the local power supply falls within this range. If this is not the case, under no circumstances

connect the AC/DC adapter to the power supply, but contact a METTLER TOLEDO representative.

• The power plug must be accessible at all times.

• Prior to use, check the power cable for damage.

• Route the cable in such a way that it cannot be damaged or cause a hindrance when working.

• Ensure that no liquid ever comes into contact with the AC/DC adapter.
22 Installation and Putting into Operation Precision and Analytical Balances

4.5 Battery Operation

The balance can be operated with batteries. Under standard operation conditions, the balance works for

about 8 hours (using alkaline batteries). After the AC power supply is interrupted e.g. by withdrawing the

power plug or if there is a power failure, the balance switches to battery operation. Once the AC power

supply is restored, the balance reverts automatically to AC operation.

Note 

Rechargeable batteries can be used. Batteries can NOT be charged by the balance.

Rechargeable batteries have a lower voltage of 1.2 V. Therefore, the battery indication shown on the

balance might differ from the actual battery status.

In battery operation mode, a battery symbol appears in the status

information field. The size of the white bar indicates the battery

condition. When the batteries status reaches 25%, part of the

symbol becomes red. If the status is lower than 15%, the whole

symbol becomes red.

100% full

Precision and Analytical Balances Installation and Putting into Operation 23

4.6 Leveling the balance

Exact horizontal positioning and stable installation are prerequisites for repeatable and accurate weighing

results.

Note 

To compensate for small irregularities or inclinations (±2 %), the instrument must be leveled and adjusted

each time it is moved to a new location.

The balance can be levelled with the leveling assistant and/or with 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.

Balances with two levelling feet

- Adjust the two front leveling feet until the air bubble comes to rest

exactly in the middle of the glass:

Air bubble at "12 o'clock" turn both feet clockwise

Air bubble at "3 o'clock" turn left foot clockwise, right

foot counterclockwise

Air bubble at "6 o'clock" turn both feet counterclockwise

Air bubble at "9 o'clock" turn left foot counterclockwise,

right foot clockwise

Balances with four levelling feet

1 First turn the two rear leveling feet all the way in.

2 Adjust the two front leveling feet as previously described.

3 Turn the rear leveling feet down onto the surface for extra

stabilizing safety, so the balance cannot tilt over under eccentric

loads.

5.10 Working with IDs

Identifications (IDs) contain descriptive text for individual measurements, which enables samples to be

easily allocated to specific tasks or customers. This feature defines identifications in order to comment

measurements, such as company ID, batch ID or sample ID.

Identifications must be defined in the contextual settings of an application. Usage and definition of the ID

differ depending on the application the ID is used for.

Identification dialog screen

The Identification dialog screen can slightly differ depending on the application in which the ID is used. The

dialog screen always consists of two parts:

• The table with the ID definitions on the upper part of the screen.

• The Workflow options on the lower part of the dialog screen.

5.10.1 Defining an ID

A new ID is defined as follows:

1 Open an application (e. g. Weighing).

2 Tap on the Main configuration symbol on the upper left corner.

3 Tap on [

5.10.2 Workflow options

The workflow handling options differ depending on the application in which they are used. The following

functions are available:

• Input prompt

• Autoincrement

• Assign to sample

Input prompt

The function Input prompt can be used for every ID. If the function 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 to define an individual value.

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).

Note

• The counter must be set at the end of the ID, otherwise the system does not recognize the number as a

counter (e.g. in 567Apple the system does not recognize 567 as a counter).

• If the ID has no counter and a maximum length of 12 characters, the last few characters will be

overwritten by the counter.

Assign to sample

If the option Assign to sample is activated, the ID will be used for each sample.
