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
Installation and Putting into Operation20 Precision and Analytical Balances

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.
Installation and Putting into Operation 21Precision 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.
CAUTION
• The balance must be disconnected from the power supply when replacing batteries.
• Do not place the balance on the pan support location bolt.
• Read and follow all warnings and instructions supplied by the battery manufacturer.
• Do not mix different types or brands of batteries. Performance of batteries varies depending on the manufacturer.
• Remove the batteries from the balance if the balance is not used for a long period of time.
• Batteries must be disposed of properly, according to local regulations.
Note
The balance works with 8 standard AA (LR6) batteries (alkaline batteries preferred).

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 counter-
clockwise
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.
