3 Installation and Putting into Operation

3.1 Selecting the location

A balance is a sensitive precision instrument. The location where it is placed will have a profound effect on the accuracy of the weighing results.
Requirements of the location
According to the environmental condition, see chapter "General data".
Ensure there is:
indoor on
stable table
Avoid:
direct sunlight vibrations strong drafts temperature
with sufficient
distance (> 15 cm)
in level adequate lit
fluctuations

3.4 Installing components

CAUTION
Injury due to breaking glass
Careless handling with the glass components can lead to breakage off glass and damage cuttings.
− Always proceed focused and with care.
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).

3.5 Connecting the balance

WARNING
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 approved METTLER TOLEDO power supply cable and AC/DC adapter with a
current-limited SELV output. 2 Connect the power cable to a grounded power outlet, ensure correct polarity. 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
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 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.

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.

3.6 Setting up the balance

3.6.1 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 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.

3.6.2 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.
12 Semi-Micro Balances
Page 13
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.

3.6.3 Adjusting the balance

To obtain accurate weighing results, the balance must be adjusted to match the gravitational acceleration at its location. This is also dependent on the ambient conditions. After reaching the operating temperature, it is important to adjust the balance in the following cases:
Before the balance is used for the first time.
If the balance has been disconnected from the power supply or in the event of power failure.
After significant environmental changes (e.g. temperature, humidity, air draft or vibrations).
At regular intervals during weighing service.
For full information, always consult and download the Reference Manual (RM).

3.7 Performing a simple weighing

The weighing application allows you to perform simple weighings and how you can accelerate the weighing process.
If your balance is not in the weighing mode, press and hold the display. Release the key. Your balance is in the weighing mode and set to zero.
