Leveling the Balance, Setting the Level Indicator
h
Leveling the balance compensates for slant or unevenness at the place
of installation. The balance must be perfectly horizontal to ensure consistent, reproducible weighing results. All models are equipped with
an electronic tilt angle detection feature. If the balance is not level,
all balance models issue an alert on the display.
Push-button automatic leveling is available on models with motorized
leveling feet. For models with manual leveling feet, please follow
the instructions on the display.
Leveling the Balance Manually
t The balance is leveled using both front leveling feet.
t Screw in both back leveling feet (only for models with back leveling feet).
t Turn the two front feet as shown in the illustration until the air bubble is cen-
tered within the circle of the level indicator.
y Normally, several leveling steps are required.
t Turn both back leveling feet until they touch the setup surface
(only for models with back leveling feet).
Warm-up Time
y To return precise results, the balance must warm up for at least 30 minutes
after initial connection to the power supply.
Only after this time will the device have reached the required operating temper-
ature.
When a verified balance used in legal metrology (legal-for-trade applications) is connected to the power, it must warm up for at least two hours
before operation.
t Turn on the devices via the A key. The following appears on the display:
y The operator can now follow the brief instructions to configure the balance
settings before beginning weighing operations.

t Level the balance.
h
Leveling the balance compensates for slant or unevenness at the place
of installation. The balance must be perfectly horizontal to ensure
consistent, reproducible weighing results. All models are equipped with
an electronic tilt angle detection feature.
If the balance is not level, the balance issues an alert (MSA and MSU
models, see brief instructions). The display shows a graphical representation of a level indicator and text prompts that guide the user through
the leveling process.
t The balance is leveled using both front leveling feet.
t Turn both back leveling feet (only for models with back leveling feet).
t Turn the two front feet as shown in the illustration until the air bubble
is centered within the circle of the level indicator.

Operating Design: Q-Guide
Cubis precision and analytical balances are controlled by application software with
interactive operator guidance. Once you open a menu or select an application, brief
instructions appear on the display to guide you through the menu or application
step-by-step. At each step along the way, the display shows only those options that
are relevant to your process; this helps prevent unnecessary “detours” and enables
you to reach your goal more quickly.
This type of user guidance is mostly intuitive. Although operation of the balance
is also mostly intuitive, this manual includes a section with very detailed, step-bystep instructions where you can learn about all of the available options
(see “Creating User Profiles” in Section “User Management”).
Basic Operational Structure
The most basic functions, weighing and taring, can be carried out as soon
as the balance is switched on. The application software is divided into three general
areas in which individual settings can be configured:
In Task Management (TASK), task profiles with specific applications, weighing
settings, and printout settings can be configured.
User Management (USER) lets you set up user profiles with specific configuration
settings and user rights. You can also set up password protection to meet your
security requirements. Your balance can also be used without User Management.
