With this Sartorius Balance you have acquired a sophisticated,

top-of-the-line electronic weighing Instrument which will help
lighten your daily work load.

Please read these installation and operating instructions care-

fully before operating your new balance.

Regulations for Prevention of Accidents "Elektrische Anla-
gen und Betriebsmittel (VBG 4)" [Electrical Installations and
Equipment] of April 1986,it is hereby certified that the

U 4100, U 4100 S, U 4800 P, U 6100, U 6100 D or U 6100
S," is manufactured and tested in compliance with the fol-
lowing DIN/VDE regulations

DIN IEC 348/VDE 0411:

Safety requirements for electronic measuring apparatus

DIN IEC 380/VDE 0806:

Safety of electrical y energized Office machines

DIN IEC 601 /VDE 0750:

Equipment Supplied.

Do not miss out on the benefits of our warranty. Please fill out
the warranty card, indicating the date of installation, and return
the card to your Sartorius dealer.

The equipment supplied comprises the components shown on

the left.

Save the packaging material and the box for shipping your bal-
ance to prevent any damage caused during transportation.

Installation Instructions.

Choose a suitable place to set up your balance. lt should not be

exposed to the following:

- heat radiation
-aggressive/corrosive substances
-vibrations
-drafts.

Your Sartorius Balance will provide accurate readouts even

when it is exposed to unfavorable conditions. You can adapt it
to your requirements simply by changing the menu code set-
tings of the balance operating program. For this purpose,
please read pages 10 through 12.

After you plug your balance into a wall outlet, allow for at least
30 minutes warmup.

Important Note
Unplug the AC adapter before you connect or disconnect pe-
ripherals.

5
 Startup.

Attach the dust cover by pressing down on the adhesive disks,

and install the pan (1) on the balance.

Your balance is powered by an AC adapter. Please make sure

that the voltage printed on this unit is identical to your local line
voltage rating.

Plug the line cord into the power receptacle of the balance and
plug the AC adapter into a wall outlet.

Level the balance using the leveling feet (3) such that air bubble
is centered within the circle on the level indicator (10) (not by
U 4100, U 6100 und U 6100 D).

6
Operation.

The weight display shows the following special

Status messages for your Information:

BUSY

The processor is still busy processing a function and will not ac-
cept any other commands to perform functions at this time.

STANDBY

The balance has been turned off with the ON/OFF key (5) and
is now in the STANDBY mode and ready to operate without
warmup.

POWER OFF

The balance was disconnected from line power (reconnection to

line power, power failure).

CAL

The calibration function has been called.

In addition to grams, this balance gives you a variety of

other international weight unit options to work with.

Select the weight unit you need from the table of the menu op-
tions for the balance operating program, and set the appropriate
code(s) as described in the section "Balance Operating Pro-
gram."

7
 Press the ON/OFF key (5) to switch the balance on or off. You
can also turn on the balance with the tare control (8).

After the adapter has been plugged into a wall outlet, the weight
display will go out when ever you turn off the balance. AII other
electronic circuits will remain energized (STANDBY state).This
means the balance is immediately ready to operate without re-
quiring warmup the next time you switch it on.

After the power is turned on, a test of all essential electronic

functions is run automatically.

The self-test ends with the readout 0.00 g/O.O g (if the program
code setting 51 1 is used).

Now place your sample on the pan (1) to determine the weight.
Read off the weight in the display (9) as soon as the weight unit
(in this case ''g") appears as the stability symbol.

lf you wish to use a Container or if the weight display does not

indicate 0.00 g/O.O g (or the equivalent with the weight unit of
your choice), press the tare control to zero the display.

8
Calibration.

External Calibration:
— Only possible with an accurate calibration weight
(U 4100, U 4100 Sand U 4800 P-2,000 g;
U 5000 D, U 6100, U 6100 D and U 61OO.S -5,000 g)
Please refer to the "Accessories."

Clear the pan and press the CAL key (6) (for the U 6100 S use
the tare control (8)) for at least three seconds until the calibra-
tion weight readout appears in the display.

Center the calibration weights on the pan.

Now the weight unit symbol is displayed. An acoustic Signal in-

dicates the end of the calibration procedure.

Internal Calibration:
(onlyfortheU6100S)
Unload the balance and zero the display. Press the CAL key (6)
as soon as the display shows a zero readout. "C" will now be
displayed. lf “CE" is displayed instead, zero the display by
pressing the tare control and press the CAL key again.

After a few seconds, "CC" will be displayed followed by 0.00 g.

An acoustic Signal indicates the end of the calibration proce-
dure.

You can block access to both the internal and external calibra-
tion functions-to find these menu codes, refer to the "Balance
Operating Program." These functions are accessible when ever
the balance operating program is unlocked by the menu access
switch (4).

9
 Balance Operating Program.

The balance operating program lets you adapt your balance to

various ambient conditions and to different weighing require-
ments and select the weight unit(s) commonly used in your
country. At the factory we have set the codes for a Standard
program, which is protected by a locking function to prevent ac-
cidental changes.

The "code" contains the information of the operating program,

lt consists of three digits: one each for the page the line and the
word.

How to access the menu of the balance operating

program:

With the balance turned off (STANDBY state), hold down the
tare control (8) and simultaneously press the ON/OFF key (5).
Upon completion of the automatic self-test, release the tare
control as soon as "CH 5" is displayed. The Status of the bal-
ance operating program will be indicated in the weight display:
"L" Stands for the list mode. In this mode you can check the
menu code settings, but you cannot program new menu codes.
lf you wish to change a program menu code, you must first
unlock the menu access switch to access the menu.

To do so slide the menu access switch (4), located at the front

right of your balance, in the direction of the arrow.

The display will indicate "C", which Stands for the change
mode, meaning you can now proceed to make the necessary
code changes.

10
After the balance operating program has been called the display
will show a continuous numerical sequence from 0 to 5 repre-
senting the "page" selection, in addition to the Status code letter
''L" or "C.'' When the code number of your choice for the "page"
appears, press the tare control. The "page" code number now
stops in the display, and a series of numbers for the "lines'' will
begin to cycle. Again, press the tare control to stop the code
number of your choice in the display. Next the numbers for the
"word'' will cycle in the display. Repeat the procedure to enter
the last digit of the code.

The "o" symbol that appears indicates the actual setting.

To change any settings ("C" mode), press the tare control as

soon as the appropriate code appears.

Brief display of BUSY and the "o" symbol confirms your selec-
tion, followed by a return to ''zero" representing the "line."

To return to the weighing program:

press the tare control each time a 0 appears in the numerical
sequence (word, line, page). lf you have made code changes
your code entry will be stored as soon as the display returns to
the weighing mode. Lock the balance operating program using
the menu access switch (display ''L") and replace the protective
cap.

Auto Zero

This balance has an automatic zero tracking function, known as

"Auto Zero" (can be turned off by menu code).
Any changes off zero ≤ 0.5 of a digit per second will be set to
zero automatically.
