Chapter 1: Setting up the scale METTLER TOLEDO SQC16

1 Setting up the scale
Please read through these operating instructions carefully and adhere to them at all times. If you discover that materials
are missing or that the wrong ones have been supplied, or if you have any other problems with your scale, please refer to
the dealer and salesperson concerned, or if necessary to the METTLER TOLEDO representative responsible.
1.1 Safety and environment
• Do not use the scale in hazardous areas (unless it is clearly identified
as being approved for these areas).
• If the power cord is damaged, the scale must no longer be operated.
Therefore check the cable regularly and ensure that a free space of about
3 cm is left at the rear of the scale, so that the cable is not kinked too
severely.
• Never tamper with the retaining screws for the load plate support
underneath the weighing pan.
• When the weighing pan is removed, never insert a solid object
underneath the load plate support.
• Never open the scale by removing the screws in its base.
• Use only approved accessories and peripherals.
• Handle the scale with utmost care; it is a precision instrument. Blows on
the weighing pan must be avoided, and heavy overloads must not be
placed on it.
• Important instructions when using scales in the food sector: those parts
of the scale can come into contact with food products have smooth
surfaces and are easy to clean. The materials used do not splinter and
are free from contaminants. In food processing areas, it is recommended
that a protective cover (accessory) is used. This must be cleaned
regularly, just like the scale itself. Damaged or heavily contaminated
protective covers must be replaced immediately.
• When the scale is finally taken out of service, observe the current
environmental regulations. The scale is equipped with a battery that
contains heavy metals and therefore must not be treated as normal
refuse! Local regulations for disposing of environmentally hazardous
substances must be complied with.
METTLER TOLEDO SQC16 Chapter 1: Setting up the scale
9
1.2 Positioning and leveling the scale
The correct location is a decisive factor in ensuring accurate weighing results.
- Choose a stable and vibration-free location (particularly important for
high-resolution scales using METTLER TOLEDO MonoBloc technology).
Place the scale on a surface that is as horizontal as possible and strong
enough to bear its weight when fully loaded.
- Check the ambient conditions.
- Avoid:
- Direct sunlight
- Strong drafts (e.g. from fans or air conditioning systems)
- Excessive temperature fluctuations.
• Turn the adjustable feet so that the scale is horizontal. If a spirit level is
filled, the bubble must be located within the inner circle.
Note: The SQC16 has a special filter that accelerates certain procedures
(zeroing, taring) in a non-tranquil environment. This inevitably means that
there is a slight loss of accuracy with the results. For high-precision results,
care must be taken to ensure as tranquil and stable an environment as
possible, so that the filter is not activated.
Major changes in geographical location:
Every scale is set by the manufacturer to suit the local gravitational
conditions (geographical adjustment value) in the geographical zone to
which the instrument is supplied. If a major change of geographical location
takes place, this setting must be adjusted by a service technician or a new
setting made. Certified scales must, in addition, be recalibrated in
accordance with national certification regulations.
1.3 Connecting to power supply
• Before connecting the power supply plug, verify that the voltage stated on
the model plate is the same as the local power line voltage.
• For maximum possible precision, adjust the scale after installing it
(Chapter
7.4.1). Note: Certified scales must be adjusted by an
authorized organization. Please consult your dealer.

14
2.6 Recording weighing results
Press the « » key to send the current weighing result to the peripheral
device (usually a printer) via a COM port which has to be set up as 'Printer'.
Please refer to Chapter
7.9 for instructions on configuring the interface(s).
METTLER TOLEDO SQC16 Chapter 3: User setup and password
15
3 User setup and password
To avoid incorrect operation of the scale in normal use, the vision setup menu can be protected with a password. The
scale differentiates between users and a supervisor. When the scale leaves the factory, the entire menu can be accessed
by anyone. We therefore recommend you to define your own supervisor password as soon as you set up the scale.
This limits access by the users to a smaller number of vision setup menu items (settings for language, sleep mode,
contrast, invert, weight display and date/time).
Note:
Please be aware that the term 'Supervisor' (valid for Vision Setup; i.e. general scale operations and SQC16
operator/administrator setup) is different from 'Operator' and 'Administrator' (valid for SQC16 specific operations).
There should be only one (unnamed) Supervisor who has access to the Supervisor password and therefore, can setup
several (named) administrators and several (named) operators, including resetting of their passwords.
Please refer to Chapter
7.2 on how to navigate within the 'Vision Setup'-menu and thus reach the menu position 'Vision
Setup Æ TERMINAL Æ Access' (Chapter
7.7) for defining the Supervisor password.
3.1 Defining a user name
Press the « » key continuously for about 2 seconds.
…appears on the screen, enter Supervisor password (if any; Æ Chapter 7.7)
and then briefly press the «
» key again.
…appears on the screen.
Select SQC16 by pressing « » and then press « ».
If you want to work with operator login, User Login should be activated.
Select User Setup and press «Edit».
…appears on the screen.
Define the user (User name, Number, Access Rights) by pressing «Edit»
again.
Chapter 3: User setup and password METTLER TOLEDO SQC16
16
Using the alphanumeric keypad of the scale, type the name of the user and
then press «OK». Up to 16 different users can be defined. Specify also
'Number' and 'Access Rights' of user, i.e. whether only as operator (who
cannot enter «
» menu within SQC16 mode) or as administrator.
Note: Password menu here is only meant to delete existing passwords in
case it was forgotten (the supervisor can erase passwords of operators and
administrators). For defining Æ Chapter
3.1. Please see also Chapter 7.5 for
more detailed information about SQC16 vision menu.
3.2 Creating a password
Once operator and administrator names are defined, a password has to be defined, as soon as the specific user enters
'SQC16' for the first time.
In weighing mode, press «SQC16».
Select the user name and then press «OK».
Using the numeric keypad of the scale, type the password and then press
«OK».
Note: The first time it will ask 'Create password' and then 'Re-type password'.
Enter the same new password twice.

In order to work with reasonable weighing results, it is recommended not to
enter Nominal values lower than 100 times the scale resolution.
Nevertheless, the system allows entries with a minimum of 30 times the
resolution.
Example BBK462SQC-3XS:
Scale resolution d = 0.01g
Minimum recommended Nominal value = 100x0.01g = 1g
Minimum allowed Nominal value = 30x0.01g = 0.3g
This warning message appears if the entered Nominal value is lower than
100 times the scale resolution.
By pressing «Yes», the minimum recommended Nominal value automatically
suggested by the system, i.e. 10 ml, is being set.
By pressing «No», the entered value is set as Nominal if it is not lower than
30 x resolution
NOTE: The minimum recommended Nominal value varies depending on the
scale resolution and article unit.
This error message appears if the entered Nominal value is lower than 30
times the scale resolution.
Press «Edit». Using the keypad, type in the tare weight and then press «OK».
Continue with the next parameter (Supplement) by pressing «
