4 Installation and Putting Into Operation

WARNING
Danger of death or serious injury due to electric shock!
The instrument must be disconnected from the power supply before performing all setup and assembly work.

4.1 Unpacking and delivery inspection

NOTICE
Risk of damage to the instrument due to the use of unsuitable parts!
Using unsuitable parts with the instrument can damage the Instrument or cause it to malfunction.
− Only use parts from METTLER TOLEDO that are intended to be used with your
instrument.
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 or User Manual; printed or on CD-ROM, depending on country of use
• Declaration of conformity

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.

4.5 Connecting the balance

WARNING
Danger of death or serious injury due to electric shock!
Contact with parts that carry a live current can lead to death or injury. 1 Only use the METTLER TOLEDO power supply cable and AC/DC adapter designed for
your instrument. 2 Connect the power cable to a grounded power outlet. 3 Keep all electrical cables and connections away from liquids and moisture. 4 Check the cables and power plug for damage and replace damaged cables and
power plugs.
NOTICE
Danger of damage to the AC/DC adapter due to overheating!
If the AC/DC adapter is covered or in a container, it is not sufficiently cooled and will overheat.
1 Do not cover the AC/DC adapter. 2 Do not put the AC/DC adapter in a container.
The balance is supplied with an universal AC/DC adapter.
• Install the cables so that they cannot be damaged or interfere with operation.
• Insert the power cable in a grounded power outlet that is easily accessible.
− Connect the AC/DC adapter to the connection socket on the back of your balance (see figure) and to the power line.
ð The balance is ready for use.

4.5.1 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 failure, the balance switches automatically to battery operation. Once the AC power supply is restored, the balance reverts automatically to AC operation.
It is also possible to use rechargeable batteries. Charging batteries inside the balance is not possible.
Your balance uses 4 standard AA (LR6) batteries (alkaline batteries preferred).
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 indicator of battery condition (3=fully charged, 0=discharged). When the batteries are almost completely discharged, the battery symbol flashes.

4.6 Setting up the balance

4.6.1 Switching on the balance

Before using 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.

4.6.2 Leveling the balance

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.
The balance must be leveled and adjusted each time it is moved to a new location. 1 Align the balance horizontally. 2 Turning the leveling feet of the balance housing
until the air bubble is in the inner circle of the level indicator.

4.6.3 Adjusting the balance

To obtain accurate weighing results, the balance must be adjusted to match the gravitational acceleration 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.
