Leveling
To ensure accurate measurement results, you need
to level the balance each time after you have moved it
to a different location.
Secura Balances
As soon as LEVEL
appears on the display,
you will need to level
the balance. Make sure
that the weighing pan
is unloaded before
you begin. Touch
LEVEL. Then follow the
prompts shown on the
interactive display.
Touch the menu key
to enter the selection
mode for applications
and functions.
Selecting the Language
Each balance has been factory preset to English.
You can select your preferred language as follows:
Touch the open-end
wrench icon.
Select Language.
Touch the desired
language and confirm
selection by touching
the checkmark.
Quintix and
Practum Balances
Turn the two feet as
shown in the picture
until the air bubble
is centered within the
circle of the level
indicator.
Initial Operation of Balances Without a Draft Shield
Touch CAL to select
the combined
calibration and adjust-
ment mode.
Quick Access to
Calibration and
Adjustment
You will need to perform the combined calibration
and adjustment procedure the first time you operate
the balance, each time after changing it to a different
location and at regular intervals during operation.
If you are using a Practum series balance, you will
have to do this manually as described below.
The Secura and Quintix series perform this procedure
fully automatically.
To perform external
adjustment, touch
CAL-Extern.
First touch A, then
w to calibrate
the balance. Place a
calibration weight
equal to that displayed
on the balance on the
pan. The balance will
now perform auto-
matic calibration and
adjustment, then it will
change to the operat-
ing mode.
Getting Started Quickly
Initial Operation of Balances with a Draft Shield
Install the following parts in
the order listed:
– In-use dust cover
– Turn the draft shield lock
to “unlocked” .
– Place the draft shield (1) on
the balance. Note: Use both
hands to hold the top struts
of the draft shield.
– Slide the side doors all the
way to the back.
– Turn the draft shield lock
to “locked” .
– Position the base plate (2),
centering ring* (3), pan
support (4), weighing pan (5)
and high-rim shield ring* (6)
on the balance.
Note: For information about
how to clean the draft shield,
see the Care and Maintenance
chapter in the Installation
Instructions.
* only for Secura with 0.1 mg
readability
Install the following parts in
the order listed:
1) In-use dust cover
2) Position the shield
disk (1) and turn it clock-
wise until it is locked
securely in place.
3) Position the pan support (2)
and the weighing pan (3).

Quick Six-Step Guide to Applications
Counting
Mixing**
Components**
Familiarize yourself with the capabilities
of your Sartorius balance and start off by
counting identical parts. The balance will
show you the quantity and the total weight.
Say you have a formula and need to weigh in
various components quickly with 100% trace-
ability, without losing track of the total
weight. Just use the Mixing application.
Do you need to compound components
according to a formula, but don’t want to
mix them immediately? The application
Components enables you to weigh your
individual ingredients into different containers
and retrieve the total amount weighed-in –
anytime at the touch of a key.
Touch the menu key to access the
selection mode for applications and
select “Counting”.
Touch the menu key to access the
selection mode for applications and
select “Mixing”.
Touch the menu key to access the
selection mode for applications and
select “Components”.

Place an empty container for your sample
on the balance and press D to tare (zero
the display).
Place an empty container on the balance
and press D to tare (zero) the container
weight.
Place the first empty container on the balance
and press D to tare (zero). Then weigh-in
component 1 and touch v to save the weight
in the memory.

Enter the reference sample quantity by
touching the application toolbar (factory
setting: 10 pcs); place this quantity in the
container and press w.
Add the first component to the
container and touch v to save the
component weight. The display will
change to 0.

The reference sample quantity you
entered will now appear on the display.
Place your total sample quantity in
the container.
Add the next component and save its
weight by touching v.

On the balance display, the piece count
of your sample will now be shown.
Touch Qnt to view the total weight.
The total weight of your sample will
now appear on the display.
If necessary, you can add further
components. Touch Net1 to view the
total weight.

Now the total weight is displayed with
a triangle (= calculated value).
You can continue to add further
components, if necessary.

Remove the container with your first
sample from the balance, the weight
reading will change to a negative value.
Now place another empty container on
the balance and press D to tare (zero).
Afterwards, you can add component 2 and
confirm using v.
To weigh-in further samples, repeat this
procedure. To display the total weight of
the components added so far, touch Net.
The total of all saved components
will now be displayed (“Sum”) with a
triangle (= calculated value). Now you
can remove the container with the
last sample.
Statistics**
Density
Unstable Conditions
Would you like to save statistics on an entire
group of different samples? Your Sartorius
balance will transfer the readings to its
statistics memory and generate a report on
the key statistical parameters.
Let’s suppose you have a solid, irregularly-
shaped object and want to precisely determine
its density. Just use the Density application
along with the Sartorius density determina-
tion kit to calculate the quality of, for example,
precious metals and plastic parts with high
accuracy.
Do you have to weigh in an extremely unstable
environment or measure the weight of an
inquisitive little mouse that just won’t sit still?
No problem. This application lets you deter-
mine the weight reliably, giving you peace
of mind about the accuracy and traceability
of your results.
Touch the menu key to access the
selection mode for applications and
select “Statistics”.
First install the density kit on your
balance by following the instructions
for the kit. Touch the menu key and
select “Density”.
Touch the menu key to access the
selection mode for applications and
select “Unstable Cond.” for unstable
conditions or objects.

This number has been factory-set to five
measurements. You can enter a different
number by touching the three dots.
For example, press 1 and 5 to enter 15
measurements and touch the checkmark
to confirm this number.
Place your sample or an animal on the
pan and press w to begin weighing
under unstable conditions.
The averaged result will be displayed
with a triangle (= calculated value).
Place your sample on the upper pan of
the density kit to view its weight in air
and press v.
