With this Sartorius balance, you have acquired
a high-quality electronic weighing instrument that will
ease your daily workload.
Please read through these installation and
operating instructions carefully before operating
your new balance.
In the first part of these installation and operating
instructions, it is assumed that you are using the factoryset menu codes.
Warranty
Do not miss out on the benefits of our full warranty.
Please complete the warranty registration card,
indicating the date of installation, and return the card
to your Sartorius office or dealer.
Storage and Shipping Conditions
Allowable storage temperature:
+5°C ... +40 °C
+41°F ...+104°F
The packaging has been designed to ensure that
the balance will not get damaged even if it is dropped
from a height of 80 cm max. (about 32 inches).
Carefully unpack the balance and check the
equipment immediately for any visible damage
as a result of rough handling during shipment.
If this is the case, proceed as directed in the section
entitled “Safety Inspection.”
1–6
Save the box and all parts of the packaging in case
you need to ship your balance. For shipping your
balance, disconnect all cables before packing. Use
only the complete original standard packaging to
prevent damage to the equipment during shipment.
Do not expose the balance unnecessarily to extreme
temperatures, moisture, shocks, blows or vibrations.
Installation Instructions
Ambient Conditions
Your Sartorius balance will provide accurate readouts
even when it is exposed to unfavorable conditions.
Please choose a suitable place to set up your balance.
It should not be exposed to the following:
The balance may not be used in hazardous
areas/locations where there is danger of explosion.
Do not expose the balance to extreme moisture
over long periods. Moisture in the air can condense
on the surfaces of a cold balance whenever it is
brought to a substantially warmer place. If you transfer
the balance to a warmer area, make sure to
condition it for about 2 hours at room temperature,
leaving it unplugged. Afterwards, if you keep
the balance connected to AC power, the continuous
positive difference in temperature between the
inside of the balance and the outside will practically
rule out the effects of moisture condensation.
You can adapt the balance to your requirements
simply by changing the code settings in the balance
operating menu. For more information, please see
Part 2, “Balance Operating Menu.”
1–7
Using Verified Balances as Legal Measuring
Instruments in the EU*
You must calibrate the balance at the place
of installation before using it as a legal measuring
instrument (see the section entitled “Adjustment/
Calibration” starting on page 1–19).
This balance is not allowed to be used for weighing
goods intended for direct sale to the public. The
type-approval certificate for verification applies only
to non-automatic weighing instruments; for
automatic operation with or without auxiliary
measuring devices, you must comply with the
regulations of your country applicable to the place
of installation of your balance. A suitable
thermometer and barometer are recommended for
monitoring ambient conditions.
For balances of accuracy class k, a thermometer
and barometer are recommended for monitoring
ambient conditions. The temperature range
indicated on the verification ID label must not be
exceeded during operation.
The balance must warm up for at least 24 hours
after initial connection to AC power or after
a relatively long power outage.
1–8
Sartorius complies with EC Directive No. 90/384/
EEC for non-automatic weighing instruments,
which has been in effect since January 1, 1993,
within the Single European Market, as well as
the accreditation of the Quality Management
System of Sartorius AG by Lower Saxony’s
Regional Administrative Department of Legal
Metrology (Niedersächsische Landesverwaltungsamt – Eichwesen) from February 15, 1993.

Important Note Concerning All Verified Balances
Approved for Use as Legal Measuring Instruments
in the EU
Provided that an official seal is required for
the verified balance, a control seal is affixed to
the balance. Unauthorized attempts to remove this
seal will irreversibly damage it. If you break
the seal, the validity of the verification will become
void, and you must have your balance re-verified.

Important Note:
Double check to make sure that the base dust cover
does not touch the weighing pan.
Preparing an LC Series Balance
with a Capacity Greater Than 12 kg
Place the weighing pan (1) on the balance.
Connecting the Balance to AC Power
The balance is powered by an AC adapter.
Make sure that the voltage rating printed on this unit
is identical to that of your local voltage.
If the voltage specified on the label or the plug design
of the AC adapter does not match the rating or
standard you use, please contact your Sartorius office
or dealer.
Use only original Sartorius AC adapters. Use of
AC adapters from other manufacturers, even if these
units have an approval identification marking from
a national testing laboratory, requires the consent of
a certified Sartorius service technician.
1–10
Plug the cord of the AC adapter into the balance.
230 V~115 V~
Then insert the plug of the AC adapter in a wall outlet.
Follow this procedure for the following balances:
AC and LC series balances with a capacity
less than12 kg
LC series balances with a capacity greater
than 12 kg:
Insert the right-angle plug in the power
receptacle (19) as shown, then tighten the slotted
screw with a screwdriver.
Now plug the AC adapter into a wall outlet.
Voltage Selection
(does not apply to balances with a capacity greater
than 12 kg)
You can select the voltage only if you use our portable
power supply (6971172) that has a European-type
plug (rounded prongs).
Connecting Electronic Devices (Peripherals)
Make sure to unplug the AC adapter from the wall
outlet before you connect or disconnect a peripheral
device (printer or PC) to or from the interface port
of the balance.
Safety Precautions
The AC adapter, rated to Class 2 (double insulation),
can be plugged into a wall outlet without taking
any additional safety precautions. The pole of the
output voltage is connected to the balance housing,
which can be grounded for operation.
The interface is also electrically connected to the
balance housing (ground).

frequency energy and, if not installed and used in
accordance with the instruction manual, may cause
interference to radio communications. It has been
tested and found to comply with the limits for a Class
A computing device pursuant to Subpart J of Part 15
of FCC rules, which are designed to provide
reasonable protection against such interference, when
operated in a commercial environment. Operation
of this equipment in a residential area is likely
to cause interference, in which case the user, at his
own expense, will be required to take whatever
measures may be required to correct the interference.
Adjusting the Display Unit of an LC Series Balance
with a Capacity Greater Than 12 kg
Tilt the display unit to adjust it to the position
you desire.
1–12
Information on Weighing Electrostatically
Charged Samples
Problems with static electricity can occur in
environments with low humidity. To avoid these
problems when you use your balance in such
an area, wipe down the entire draft shield on both
the inside and outside with a commercially
available antistatic agent.
If you need to use electrostatically charged glass or
plastic containers that have a relatively large diameter
with balances that have a readability of 0.1mg,
you should utilize our antistatic pan (155 mm Ø –
see “Accessories” in Part 6) instead of the standard
weighing pan.
Leveling the Balance Using the Level Indicator
At the point of use, level the balance using the
leveling feet (21) as follows so that the air bubble is
centered within the circle of the level indicator (17):
Screw in the auxiliary foot (22) located on the front
right-hand side of the balance.
To level the balance using the level indicator
as a guide:
Extend the leveling feet (turn clockwise) to lift
the balance.
Retract the feet (turn counterclockwise) to lower
the balance.
Afterwards, extend the auxiliary foot (22) until it
touches
the surface on which the balance is resting.
1–13
Operating the Balance
Warmup Time
After initially connecting the balance to AC power
(or after a relatively long power outage), the balance
will need to warm up for at least 30 minutes.
Turning the Display On and Off (Standby Mode)
Press the e key (14) to turn the display on and off.
Self-Test
After the balance has been turned on, an automatic
self-test of theelectronic circuitry will be performed.
The self-test ends with a zero readout; the balance is
then ready to operate.
1–14
Important Note Concerning Verified
Balances/Scales Approved for Use as Legal
Measuring Instruments in the EU:
For verified balances that have a verification scale
interval “e” which is greater than the scale interval
“d,” the last digit on the display is bordered.
The weight display shows the following special codes
for your information:
OFF
The balance was disconnected from AC power
(i.e., power failure or outage; the balance
was disconntected, then reconnected to AC power).
O (STANDBY)
The display has been turned off using the e key (14),
and the balance is now in the ready-to-operate mode
and does not require warmup.
b (BUSY)
Once you have turned on the balance, the b symbol
will remain displayed until you press a key. During
operation, this symbol indicates that the balance
processor is still busy processing a given function and
will not accept another command to perform any
other function at this time.
R1 or R2
The number in the R code identifies the particular
weighing range you have selected.
W
Symbol for the selected application (in this case, the
weighing mode).
CAL I
The balance has an internal calibration weight.
1–15
Taring
A weight can be accurately measured only from
a defined zero point. Press one of the two t keys (10)
to zero the display. You can tare the display within
the entire weighing range.
Important Note Concerning Verified
Balances/Scales Approved for Use as Legal
Measuring Instruments in the EU:
The small circle on the left in the weight display
shows that the balance/scale has been exactly
tared to “0” (±0.25 of a scale interval).
Weighing
Place your sample on the weighing pan (1) to
determine the weight. Read off the weight indicated
in the display (6) only once the weight unit/stability
symbol (“g”, “kg” or a different unit as selected – see
Part 2, “Balance Operating Menu”) is indicated.
Important Note Concerning Verified

Weighing Range Structure
SuperRange
(identified by S in the model designation AC/LC.....S)
“Single wide-range balance”
SuperRange models have an extraordinarily high
resolution; i.e., the weighing range has a resolution
ranging from100,000 to a few million digits. There is
one level of fine readability for the entire weighing
range (for example: 0.01g).
DualRange
(identified by D in the model designation LC.....D)
2 weighing ranges: a fine range and a standard range
1000g0.01g
4800g
3000g
0.00g
1600g
800g
0.1 g
0.05g
0.02g
0.01g
The balance automatically switches from the fine range
which is10 times more accurate (e.g.1,000 g
capacity – 0.01g readability) to the standard range
(e.g., a 3,200 g capacity – 0.1 g readability)
when the balance is loaded beyond the fine range
limit (>1,000 g).
The weight readout is displayed with the lower
readability of the standard range until you tare in the
fine range (<1,000 g).
PolyRange
(identified by P in the model designation AC/LC.....P)
PolyRange models have a wide weighing range
with multiple levels of accuracy that change as the
load increases or decreases.
The PolyRange function divides the weighing range
into as many as 4 ranges, each with a different
readability. In the various ranges, the readability will
adjust so that the last numeral of a weight readout
is displayed with a resolution of 1, 2, 5 or 10 digits
(10 = only the next to the last numeral displayed
changes; the last numeral is blanked).
After you press the tare key (10), you will obtain
the highest possible resolution, even when the balance
is loaded.
1–17
Weighing in the IQ-Mode*
(Load-Dependent Readability)
In the IQ-mode, weighing is done with a loaddependent readability of 0.1% (for different settings,
see part 2, “Balance Operating Menu”) throughout
the entire weighing range of the balance. The display
resolution of the last digit changes in increments of 1,2,
5,10, 20, etc., in proportion to the weight of a sample.
Oftentimes, a display accuracy of 2 grams
is sufficient for a load of approx. 2 kg. In this case, it
makes sense to select weighing range R 2 with anaccuracy of 0.1% by pressing the w key (8). While
you are filling up to a target weight, it is certainly
easier to work with a target of 2220 g than with an
absolutely accurate readout of 2219.92 g.
1–18
By selecting the IQ-mode for automatic adaption
of the display accuracy, you will obtain stable weight
readouts even faster.
In daily laboratory routines, analyses must often be
performed with a certain accuracy. The IQ-mode
meets this requirement – on an analytical balance, it
gives you the full accuracy of all 4 decimal places for
initial sample weights below1g, whereas for heavier
samples (of100 g or more), it provides a lower
readability, which is sufficient:
Initial sample weightReadout
Below1 g→0.9876 g
Above 100 g→ 123.4g
For other readabilities (0.01% – 1%) see page 2–11
of the “Balance Operating Menu.”
* = not applicable to verified balances approved for
use as legal measuring instruments in Europe; on
GC 1201G scales, menu code 3 2 9 must be set
Adjustment/Calibration
During calibration1), the balance is adapted to
changes in ambient conditions.
You should recalibrate your balance each time you
set it up in a different area or when the ambient
conditions (such as the temperature or the barometric
pressure) have changed.
Independent of such changes, you should calibrate
balances acceptable for legal metrological
verification at least once a day (i.e., even when
the ambient conditions remain constant). To meet the
highest requirements for accurate weighing, we
recommend that you calibrate the balance before
each weighing series.
The balance offers you various calibration functions.
The function you select is indicated in the display
by one of the following codes:
“CAL” : calibration function is activated
“C– I” : internal calibration
“C– E” : external calibration
“C– t” : sensitivity test
“CAL I”: the balance has an internal
calibration weight
You can use the c key (13) to interrupt any
calibration process.
1
) “Calibration” technically means to determine
the difference between the balance readout and
the actual weight on the pan to determine the
accuracy. Adjustment means to bring a balance
into the state of accuracy required for its use.
Therefore, “calibration,” as used in this manual,
actually means “adjustment.”
1–19
The balance may or may not have an internal
calibration weight:
– On standard balances, it depends on the model
(see Part 6, “Specifications”)
– Verified balances generally have an internal
calibration weight
Using Verified Balances/Scales as Legal
Measuring Instruments in the EU:
Before using your balance as a legal measuring
instrument, you must carry out an “Internal
Calibration” operation at the place of installation
after the warmup period.
1–20
INTERNAL CALIBRATION
Quick-CAL Function Using the f Key:
Unload the pan and tare.
Once the display indicates a zero readout, press
the f key (7).
“C” will now be displayed. The built-in calibration
weight is internally applied by servomotor and
removed at the end of calibration.
If external interference affects the calibration
procedure, you may obtain a brief display of the error
message “Err 02.”
In this case, tare the display; then press the f key
again once a zero readout is indicated.
An acoustic signal indicates the end of calibration.
Internal Calibration Using the Tare Key:
2 sec.
Calibrate the balance using the tare control if an
application program (such as “tare memory”) is
assigned to the f key by menu code in the balance
operating menu (see parts 2 and 4).
Press the tare key (10) for at least 2 seconds until “C–I”
and “CAL” are displayed (next to the f key).
Unload the pan and tare.
Once the display indicates a zero readout, press
the f key (7).
“C” will now be displayed. The built-in calibration
weight is internally applied by servomotor and
removed at the end of calibration.
If external interference affects the calibration
procedure, you may obtain a brief display of the error
message “Err 02.”
In this case, tare the display; then press the f key
again once a zero readout is indicated.
An acoustic signal will indicate the end of the
calibration process.
!
Important Note:
The weighing pan must be left unloaded when using
the internal calibration function.
1–21
EXTERNAL CALIBRATION*
Use only calibration weights with the same
or better accuracy than that of the readability of your
particular balance.
Unlocking the Access Switch on Verified Balances/
Scales of Accuracy Class k:
– on balances with a capacity less than 12 kg,
remove the protective cap (5) on the front, right-hand
side of the unit
– on balances with a capacity greater than12 kg,
remove the large screw (5) located on the left-hand
side of the rear panel
– move the switch (5) in the direction of the arrow
2 sec.
Press the tare key (10) for at least 2 seconds until
“C– E” or “C– I” (only for balances with an internal
calibration weight) and “CAL” are displayed
(next to the f key).
Important Note:
If you press the f key (7) while “C–I” is displayed,
this will activate the internal calibration function.
For external calibration of balances
with an internal calibration weight,
press the F key (12).
1–22
“C– E” stands for “external calibration.”
Unload the balance and tare.
Press the f key (7) once a zero readout is
indicated. Afterwards, the calibration weight readout
will be indicated.
If external interference affects the calibration
procedure, you may obtain a brief display of the error
message “Err 02.”
In this case, tare the display; then press the f key
again once a zero readout is indicated.

For accuracy class K verified precision
balances/scales, this function is allowed to be
used only if the balance is not being operated
as a legal measuring instrument.
Center the calibration weight on the weighing pan.
An acoustic signal will indicate the end of the
calibration process.
Important Note for Accuracy Class K
Verified Balances/Scales Approved for Use
as Legal Measuring Instruments in the EU:
After verification, the “external calibration” function
is blocked by the access switch (5) (adjusted
to the left and secured against alteration of the
switch setting).
SENSITIVITY TEST (special function for balances
with a built-in calibration weight)*
Rather substantial changes in barometric pressure
and temperature may affect the display response
of these highly accurate balances. To ensure that you
obtain the full accuracy of these balances, even
when you use the entire weighing range, we have
implemented a sensitivity test function. It will help
you decide quickly whether or not you need to
recalibrate your balance (for example, to maintain the
same accuracy during long-term weighing series).
2 sec.
Press the tare key (10) for at least 2 seconds until
“C– I” and “CAL” are displayed (next to the f key).
Select the sensitivity test by pressing the F key (12) twice.
* = Not on verified LC balances
1–23
Unload the balance and tare.
“C– t” stands for “calibration sensitivity test.”
Once the display indicates a zero readout, press the
f key (7). The built-in calibration weight will now
be internally applied by servomotor. Then the
deviation of the current readout from the target weight
(displayed in grams only) will be indicated.
If external interference affects the calibration test,
you may obtain a brief display of the error message
“Err 02.”
In this case, tare the display; then press the f key
again once a zero readout is indicated.
Important Note:
The balance/scale should be calibrated if the
deviation of the readout from zero is more than the
reproducibility specified for standard balances
and more than the verification scale interval specified
for balances/scales acceptable for verification.
For reproducibilities and verification scale intervals,
see the “Specifications” that apply to your balance/
scale in Part 6.

Data Interface
If you wish to record your weighing results using
a Sartorius Data Printer, plug the printer connector into
the interface port (20) of the balance.You do not
need to adjust any settings.
Important Note for Balance/Scale Models Verified
for Use as Legal Measuring Instruments:
When using the balance/scale as a legal
measuring instrument (legal for trade), you are
allowed to connect to it only peripherals authorized
by law. However, if you are not using the
balance/scale as a legal measuring instrument, you
may connect to it any peripherals you wish, e.g.,
additional displays, personal computer, etc. Such
peripherals must be marked to indicate that they are
not allowed to be used when the balance/scale is
being used as a legal measuring instrument.
Remove the protective cap from the data
interface port.
Caution:
Make sure to unplug the AC adapter from the wall
outlet before you connect or disconnect any
peripherals (printer or PC) to or from the interface port
of the balance.
To print data on hard copy or have them output onscreen on an on-line computer, press the p key (11).
For information on special data output parameters,
see “Utilities” in Part 2.
For details on the data interface (such as the
data output or input formats, pin assignment, etc.)
or on interfacing a remote display, see Part 5,
“Interface Description.”

Interfacing Devices with the Balance
Please note that the interface port is electrically
connected to the protective grounding conductor
of the balance housing. The interface cables supplied
as standard equipment are shielded, and both ends
of each cable are electrically connected to the
connector cases. This connection may result in interference caused by ground loops or by transient
currents if you have grounded the housing or
connected the protective grounding conductor
for line power. If necessary, connect an equipotential
bonding conductor to the balance.
