d) Intentional disconnection of the equipment grounding conductor is forbidden.
The balance is supplied with an AC adapter and country-specific power cable. The AC adapter is suitable for use
with the following voltage range:
100 – 240 VAC, 50/60Hz.
Attention
• Check whether your local power supply falls within this range. If this is not the case, under no circumstances
connect the AC 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 comes into contact with the AC adapter.

4.5 Setting up the balance
4.5.1 Weighing for the first time
After commissioning the new balance, the first weighing can be carried out. This will also familiarize you with the
operation of the balance.
If the balance is not exactly level, a warning text is generated after switching on the balance with the request to level
the balance.
4.5.1.1 Switching on the balance
§ Balance is connected to the power supply.
§ Terminal and balance are interconnected.
- To switch on, press [
ð Display appears.
ð Balance is ready to use.
4.5.1.2 Leveling the balance
The balance has a built-in level sensor which permanently monitors correct horizontal alignment.
If the level sensor detects incorrect leveling, the status light at the
terminal shows red. A warning text is displayed and an audible
warning generated. A status icon also appears in the top right
corner of the display.

message.
ð Window with level indicator is displayed in real-time.
2 Observe the level indicator on the screen.
ð The air bubble in the level indicator shows red with incorrect
alignment.
ð The leveling assistant indicates with red arrows the direction
in which the two foot screws at the rear of the balance must
be turned.
3 Turn the foot screw until the air bubble is located in the inner
circle of the level indicator.

alignment.
ð The status light at the terminal shows green.
4 Tap [OK].
ð A message recommending adjustment of the balance is
displayed.
5 Tap [Adjust.int] to adjust the balance.
4.5.1.3 Performing a simple weighing
To perform a simple weighing, only the keys in the lower part of the terminal are required. The balance has separate
keys for zeroing [

Note
A negative weight is not permitted. An error message is generated. When the stability detector icon extinguishes
(small ring left of the weight display), the indication is stable. The weight is displayed.

Congratulations!
The first weighing is now complete. The following sections contain further information about the extensive functions
and applications of this balance.
4.5.2 Operating of the outer draft shield and the inner draft shield
Outer draft shield
The outer draft shield of the balance can be adjusted to the ambient conditions, weighing method and material to be
weighed.
The outer glass draft shield doors can be opened and closed by pressing [
manually .
Installation and Putting into Operation26 Comparator Balances
], with the "SmartSens" sensors or
Page 27
Try different combinations by moving the 3 handles upwards/inwards and downwards/outwards. We recommend
1
aligning the glass draft shield so that only those parts are opened that are required for loading. The balance then
operates faster due to less disturbing air flows than with a fully open glass draft shield.
Note
It is recommended to make connections when the draft shield is closed.
Motorized operation
The automatic door function opens and closes the doors of the glass draft shield automatically when required.
Example
• Doors open automatically for loading the tare weight when [
] is pressed.
• When a request is made to load the adjustment weight while adjusting the balance, the doors open
automatically. The doors close automatically when the weight is loaded.
• The glass draft shield closes automatically for all weighings to achieve a stable weight indication.
• For different operations (e.g. piece counting), the doors open and close automatically as required by the
application.
§ Handles are locked.
1 Move the handles for the side
doors inwards.
2 Move the handle for the top
door into the horizontal
position.
ð The door is automatically
opened when required.
Manual door operation
The doors must be opened or closed manually. With the [
] keys, via SmartSens or manually.
§ Handles are unlocked.
1 Move the handles for the side doors outwards.
2 Move the handle for the top door into the vertical position.
3 Press [
].
or
Move the hand over the SmartSens sensor.
ð The door is opened.
Inner draft shield
- For motorized operation of the inner draft shield the coupling
bolts (1) must be pressed inward.
ð The two side doors can be controlled separately.
You can also open the side doors of the inner draft shield only
partway, with a choice of 25%, 50% or 75%.

5 Maintenance
5.1 Cleaning
Periodically clean the weighing pan, the drip tray, the housing, and the terminal of your balance using the brush
supplied with it. The maintenance interval depends on your standard operating procedure (SOP).
Please observe the following notes:
WARNING
Risk of electric shock
a) Disconnect the balance from the power supply prior to cleaning and maintenance.
b) Only use METTLER TOLEDO power cable, if these need to be replaced.
c) Ensure that no liquid comes into contact with the balance, terminal or AC adapter.
d) Do not open the balance, terminal or AC adapter.
These contain no user-serviceable parts.
CAUTION
Damage to balance
Under no circumstances use cleaning agents containing solvents or abrasive agents, as this can
damage the terminal overlay.
Cleaning
Your balance is made from high quality, resistant materials and can therefore be cleaned with a commercially
available, mild cleaning agent.
Note
All removable non-coated parts of the outer draft shield are dishwasher safe to 80 degrees. The sealing cover of the
inner draft shield is not dishwasher safe.
1 To clean the weighing chamber thoroughly, move the draft shield glass panels (including intermediate shelf)
away from the balance and remove them from their fastenings.
2 Carefully lift the front of the weighing pan and lift it out of the guide.
3 Remove the drip tray from the balance.
4 Ensure that these parts are correctly positioned when refitted.
Note
Contact a METTLER TOLEDO representative to find about the service options available – regular maintenance by an
authorized service engineer will ensure consistent weighing accuracy over the long term and extend the service life
of the balance.

6.2 Explanatory notes for the METTLER TOLEDO AC adapter
The certified external power supply which conforms to the requirements for Class II double insulated equipment is
not provided with a protective earth connection but with a functional earth connection for EMC purposes. This earth
connection IS NOT a safety feature. Further information about conformance of our products can be found in the
brochure "Declaration of Conformity" which is coming with each product.
In case of testing with regard to the European Directive 2001/95/EC the power supply and the balance have to be
handled as Class II double insulated equipment.
Consequently an earth bonding test is not required. Similarly it is not necessary to carry out an earth bonding test
between the supply earth conductor and any exposed metalwork on the balance.

Because the balance are sensitive to static charges a leakage resistor, typically 10 kΩ, is connected between the
earth connector and the power supply output terminals. The arrangement is shown in the equivalent circuit diagram.
This resistor is not part of the electrical safety arrangement and does not require testing at regular intervals.
