4.3 Selecting the Location and Leveling the Balance

Your balance is a precision instrument and will thank you for an optimum location with high accuracy and dependability.

4.3.1 Selecting the Location

Select a stable, vibration-free position that is as horizontal as possible. The surface must be able to safely carry the weight of a fully loaded balance.

Observe ambient conditions (see Technical Data).

Avoid the following:

●

Direct sunlight

4.3.2 Leveling the Balance

●

Powerful drafts (e.g. from fans or air conditioners)

●

Excessive temperature fluctuations

The balances have a level indicator and two or four adjustable leveling feet to compensate for slight irregularities in the surface of the weighing bench. The balance is exactly horizontal when the air bubble is in the middle of the level glass.

Note: The balance should be leveled and adjusted each time it is moved to a new location.

Balances with 2 leveling feet

Adjust the two front leveling feet appropriately 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

16 Setting up the Balance

Balances with 4 leveling feet

a) First turn the two rear leveling feet all the way in.

b) Adjust the two front leveling feet as previously described.

c) Turn the rear leveling feet down onto the surface for extra stabiliz

ing safety, so the balance cannot tilt over under eccentric loads.

4.4 Power Supply

Allow your balance to warm up for 30 minutes (0.1 mg models 60 minutes) to enable it to adapt itself to the ambient conditions.

4.4.1 AC Operation

Your balance is supplied with an country-specific AC 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 exact specifications, see section "technical data").

First, check the local line voltage is in the range 100 - 240 VAC, 50/60 Hz and whether the power plug fits your local power supply connection. If this is not the case, on no account connect the balance or the AC adapter to the power supply, but contact the responsible METTLER TOLEDO dealer.

Important:

●

Before operating, check all cables for damage.

●

Guide the cables so that they cannot become damaged or interfere with the weighing process!

●

Take care that the AC adapter cannot come into contact with liquids!

●

The power plug must be always accessible.

Connect the AC adapter to the connection socket on the back of your balance (see figure) and to the power line.

4.4.2 Battery Operation

The Balance can also operates with batteries. Under normal operation conditions, the balance works indepen dently of the AC power line for about 8 to 15 hours (using alkaline batteries). Immediately after the AC power supply is interrupted e.g. by withdrawing the power plug or if there is a power failure, the balance switches automatically to battery operation. Once the AC power supply is restored, the balance reverts automatically to AC operation.

Note: It is also possible to use rechargeable batteries. Charging batteries inside the balance is not possible.

Inserting / Replacing Batteries

The balance must be disconnected from the power supply when carrying out all setup and mounting work.

●

Make sure that the balance is off before removing or inserting batteries.

●

Do not place the balance on the pan support location bolt.

●

Battery Warnings: Read and follow all warnings and instructions supplied by the battery manufacturer.

●

Do not mix different types or brands of batteries. Performance of batteries can vary very greatly depending on the manufacturer.

the display lights up. The number of segments that are lit is an indica tor of battery condition (3 = fully charged, 0 = discharged). When the batteries are almost completely discharged, the battery symbol flashes.

●

If you don't operate the balance with batteries for an extended period, it is recommended to remove the batteries from the balance.

●

Batteries must be disposed of in an environmentally responsible manner. No attempt must be made to incinerate or disassemble item.

Your balance uses 8 standard AA (LR6) batteries (alkaline batteries preferred)

a) Remove weighing pan, pan support and draft shield element or

draft shield "100 mm" if present.

b) Turn the balance carefully on its side.

c) Open and remove the battery-chamber cover.

d) Insert / replace the batteries with the correct polarity as shown in

the battery holder.

e) Insert and close the battery-chamber cover.

f) Turn the balance carefully to its normal position.

g) Reinstall all components in the reverse order.

4.5 Transporting the Balance

Switch off the balance and remove the power cable and any interface cable from the balance. Refer to the notes in Section "Selecting the location" regarding the choice of an optimal location.

Setting up the Balance

Transporting Over Short Distances

For balances with a draft shield: Observe the following instructions to transport your bal ance over a short distance to a new location: Never lift the balance using the glass draft

shield. The draft shield is not sufficiently fastened to the balance.

Transporting Over Long Distances

If you would like to transport or send your balance over long distances, use the complete original packaging.

4.6 Weighing Below the Balance

The balances are equipped with a hanger for carrying out weighings below the work surface (weighing below the balance).

Attention:

●

Do not place the balance on the pan support location bolt.

a) Switch off the balance and remove the power cable and any

interface cable from the balance.

b) Remove weighing pan, pan support and draft shield element

or "Easy draft shield" if present.

c) Turn the balance carefully on its side.

d) Remove one of the caps (A) depending on the models.

e) Then turn the balance to its normal position and simply rein

stall all components in the reverse order.

4.7 Adjustment (Calibration)

To obtain accurate weighing results, the balance must be adjusted to match the gravitational acceleration at its location. Adjusting is necessary:

●

before the balance is used for the first time.

●

at regular intervals during weighing service.

●

after a change of location.

4.7.1 Adjustment with Internal Weight

Note: On models with internal weight only (see technical data).

To obtain accurate results, the balance must be connected to the power supply for approximately,

●

30 minutes for balances with redability of 1 mg to 5 g

●

60 minutes for balances with redability of 0.01 mg to 0.1 mg

in order to reach operating temperature before adjusting.

22 Cleaning and Service

Every now and then, clean the weighing pan, draft shield element, bottom plate, draft shield (depending on the model) and housing of your balance. Your balance is made from high-quality, durable materials and can therefore be cleaned using a damp cloth or with a standard, mild cleaning agent.

Please observe the following notes:

●

The balance must be disconnected from the power supply

●

Ensure that no liquid comes into contact with the balance or the AC adapter.

●

Never open the balance or AC adapter – they contain no components, which can be cleaned, repaired or replaced by the user.

●

On no account use cleaning agents which contain solvents or abrasive ingredients, as this can result in damage to the operation panel overlay.

●

Do not use wet, but only damp cloth for cleaning.

Please contact your METTLER TOLEDO dealer for details of the available service options. Reg ular servicing by an authorized service engineer ensures constant accuracy for years to come and prolongs the service life of your balance.

23.2 MT-SICS Interface Commands and Functions

Many of the balances and scales used have to be capable of integration in a complex computer or data acqui sition system.

To enable you to integrate balances in your system in a simple manner and utilize their capabilities to the full, most balance functions are also available as appropriate commands via the data interface.

All new METTLER TOLEDO balances launched on the market support the standardized command set "METTLER TOLEDO Standard Interface Command Set" (MT-SICS). The commands available depending on the functionality of the balance.

Basic information on data interchange with the balance

The balance receives commands from the system and acknowledges the command with an appropriate response.

Command formats

Commands sent to the balance comprise one or more characters of the ASCII character set. Here, the following must be noted:

●

Enter commands only in uppercase.

●

The possible parameters of the command must be separated from one another and from the command name by a space (ASCII 32 dec., in this description represented as ).

79Interface Specification

●

The possible input for "text" is a sequence of characters of the 8-bit ASCII character set from 32 dec to 255 dec.

●

Each command must be closed by CRLF (ASCII 13 dec., 10 dec.). The characters CRLF, which can be inputted using the Enter or Return key of most entry keypads, are not listed in this description, but it is essential they be included for communication with the balance.

Example

S – Send stable weight value

Command S Get the current stable net weight value.

Response S

S WeightValue Unit Current stable weight value in unit actually set

under unit 1.

S I Command not executable (balance is currently

executing another command, e.g. taring, or timeout as stability was not reached).

S + Balance in overload range.

S - Balance in underload range.

Example

Command S Query a stable weight value.

Response S S 100.00 g The current stable weight value is 100.00 g.

The available MT-SICS commands are listed in the table (depending on the model). For further information please refer to the Reference Manual "MT-SICS 11780711" downloadable from the Internet under
