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 with draft shield
• Weighing pan with pan support
• Draft ring
• Drip tray
• Protective cover
• AC/DC adapter
• Power cable (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.
Installation and Putting into Operation10 Jewelry Semi-Micro Balances
• No powerful vibrations
C

3
• 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.

4.3 Installing components

Push the side glass doors back as far as will go and place the following components on the balance in the specified order:
1 Place the drip tray (1) into the correct position. 2 Place the weighing pan (3). 3 Place the draft ring (2).

4.4 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.
The balance is supplied with an AC/DC adapter and a country-specific power cable.
• 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.
2 Do not put the AC/DC adapter in a container.

on the back of your balance (see figure) and to the
power line. 2 Screw the plug tight to the balance. ð The balance is ready for use.

4.5 Setting up the balance

4.5.1 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 60 minutes.
Switching on
− Press On.
ð The balance performs a display test. All
segments in the display light up briefly, WELCOME and software version. Maximum load and readability appears briefly. (Startup FULL mode only).
ð The balance is ready for weighing or for operation
with the last active application.
Legal-for-trade
Approved balances will execute an initial zero.

4.5.2 Leveling the balance

The balance has a level indicator and two 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. To level it, proceed as follows: 1 Position your balance at the selected location. 2 Align the balance horizontally.
Installation and Putting into Operation12 Jewelry Semi-Micro Balances
C
È
3 Turning the two front leveling screws of the housing
until the air bubble is in the inner circle of the level indicator.
Example
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.

4.5.3 Left/right operating of the glass draft shield

The glass draft shield of your balance can be adapted to the
environmental conditions and your weighing style, as well as to the
type of weighing and loading.
The position of the handles determines which door(s) of the draft
shield (left, right, or both) is/are opened.
Try various different combinations by moving the external handles
into the upper or lower position. We recommend you to set up the
glass draft shield so that it only opens on the side where the balance
is loaded. Your balance then works faster, because there are fewer
troublesome currents of air than when both doors of the draft shield
are opened together.

4.5.4 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.
• when the balance was disconnected from the power or in case of power failure.
• after a change of the location.
• at regular intervals during weighing service.

4.6 Adjustment (calibration)

4.6.4 Customer fine adjustment

NOTICE
This function should be executed only by trained personnel.
The function customer fine adjustment ADJ.CUST.F allows you to adjust the value of the internal adjustment
weight with your own adjustment weight. The adjustable range of the adjustment weight is possible only in
a very small range. Customer fine adjustment impacts the function of internal adjustment. The customer fine
adjustment can be deactivated at any time.
Note
• This feature is available on models with internal weight only.
• Because of certification legislation, approved models cannot be adjusted with customer fine adjustment
(depending on selected countries' certification legislation).
• Use certificated weights.
• Balance and test weight have to be on operating temperature.
