5Introduction

2Safety Information
Always operate and use your balance only in accordance with the instructions contained in this manu al. The instructions for setting up your new balance must be strictly observed.
If the balance is not used according to these Operating Instructions, protection of the balance may be impaired and METTLER TOLEDO assumes no liability.
It is not permitted to use the balance in explosive atmosphere of gases, steam, fog, dust and flammable dust (hazardous environments).
For use only in dry interior rooms.
Do not use sharply pointed objects to operate the keyboard of your balance! Although your balance is very ruggedly constructed, it is nevertheless a precision instrument. Treat it with corresponding care.
Do not open the balance: It does not contain any parts which can be maintained, repaired, or replaced by the user. If you ever have problems with your balance, con tact your METTLER TOLEDO dealer.
Use only balance accessories and peripheral devices from METTLER TOLEDO; they are optimally adapted to your balance.
Use only the original universal AC adapter delivered with your balance.

4Installation and Putting Into Operation
4.1Scope of delivery
1 Open the packaging and carefully remove all components.
2 Check the delivered items. The standard scope of delivery contains the following items:
●
Balance
●
Weighing pan and weighing pan support
●
Protective cover for load cell cone (mounted)
●
Protective cover (mounted)
●
Stackable cover
●
Universal AC/DC adapter (country specific)
●
Operating instructions printed or on CD-Rom depending on the country.
●
Quick Guide (English) depending on the country.
●
EC declaration of conformity
4.2Selecting a location
The correct location makes an important contribution to the accuracy of the weighing results of preci sion balances. 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 (page59).
Avoid the following:
●
Vibrations
●
Excessive temperature fluctuations
●
Direct sunlight
●
Powerful drafts (e.g. from fans or air conditioners)
4.3Leveling the balace
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.
Align the balance horizontally by turning the leveling feet of the balance housing until the air bubble is in the inner circle of the level indicator.
Note: The balance should be leveled and adjusted each time it is moved to a new location.

1 Remove the protective cover for weighing
cone (1). Keep it for later use.
2 Place the following components on the bal
ance in the specified order:
• Pan support (2)
• Weighing pan (3)
4.5Installation of the protective cover
Install the protective cover according to the illustration on the right, using a screwdriver.
14 Installation and Putting Into Operation
4.6Using the stackable cover
The stackable cover can be placed on the balance. It protects the balance from dust when it is not used and allows you to stack up a maximal number of 5 balances.
4.7Power supply
4.7.1AC operation
Your balance is supplied with an country-specific AC/DC adapter. The power supply is suitable for all line voltages in the range: 100 - 240 VAC, 50/60 Hz (for detailed specifications, see section "techni cal 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.
4.7.2Battery operation
The Balance can also operate with batteries. Under normal operation conditions, the balance works independently 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 fail
15Installation and Putting Into Operation
ure, 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.
battery full
When the balance is operating on its batteries, the battery symbol in the display lights up. The number of segments that are lit is an
2/3 full
indicator of battery condition (3 = fully charged, 0 = discharged). When the batteries are almost completely discharged, the battery symbol flashes.
1/3 full
battery empty
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.
●
Never put the balance on the weighing cone without mounted cone protection.
The load cell could be damaged.
●
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.
●
If you don't operate the balance with batteries for an extended period, it is recom mended 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 4 standard AA (LR6) batteries (alkaline batteries preferred)

7 Reinstall all components in the reverse order.
4.8General requirements
4.8.1Switching on the Balance
Before working with the balance, it must be warmed up in order to obtain accurate weighing results. To reach operating temperature, the balance must be acclimatized and connected to the power supply for at least 30 minutes.
4.8.2Adjusting the Balance
To obtain accurate weighing results, the balance must be adjusted to match the gravitational accelera tion at its location and depending on the ambient conditions. After reaching the operation temperature, adjusting is necessary
●
before the balance is used for the first time.
●
after a change of the location.
●
at regular intervals during weighing service.
4.9Adjustment
4.9.1Adjustment with external weight
Note:
Approved models must be adjusted at the place of operation. Before putting in operation, and depend ing on particular country certification legislation, the balance will then have to be checked and sealed by authorized personnel. See the detailed information delivered with this instrument.
