Warranty
Do not miss out on the benefits of our full warranty.
Please contact your local Sartorius office or
dealer for further information. If available, 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 to +104°F
The complete packaging has been designed to ensure
that the balance will not be damaged even if it is
dropped from a height of 80 cm (about 31 inches).
After unpacking the balance, please check
it 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.”
Save all parts of the packaging and the box for
your balance to avoid damage during
transportation. Ship your balance only in the
complete original standard packaging supplied.
The packaging consists of the following:
– 2 boxes
– 3 polystyrene inserts
– 2 polypropylene pads
The inner packaging is not suitable for shipping
because it provides the balance little protection from
blows. Before packing your balance for shipment,
unplug all connected cables to prevent damage.
Do not expose the balance unnecessarily to extreme
temperatures, moisture, shocks, blows or vibrations.
1–4
Transporting the Balance
To transport the balance, lift it by the housing base
using both hands. Never lift your balance by grasping
the display unit or the draft shield!
Transport Arrestment
Before unplugging the balance from the power
supply or unplugging the connecting cable, turn off
the balance using the e key (31).
For MC5 (-0CE) and SC 2 (-0CE):
After approximately 10 seconds, the balance will
be arrested, or locked, for transportation.
While the balance is raising the weights after you
have turned it off, the symbol “Mot” from a calibration
or linearization procedure is displayed.
Warmup Time
Condition your balance for 12 hours to the temperature
of a new location. After initially connecting the
balance to AC power (or after a relatively long power
outage), allow it to warm up for at least 2 hours.
Each time you move your balance to another location,
you must condition it for at least 12 hours to the
new location.
After initially connecting the balance to AC power
(or after a relatively long power outage), allow the
balance to warm up for at least 2 hours.

Note to Users of Verified Balances Approved for Use
as Legal Measuring Instruments:
Preparing a Verified Balance for Use as a Legal
Measuring Instrument:
After initially connecting the balance to AC power
(or after a relatively long power outage), allow
it to warm up for at least 24 hours.
Linearization after Transport
After transport, the linearity and calibration of your
balance may be out of the permissible tolerances
(see the “Specifications”). Always carry out internal
linearization of the balance after transport.
Repeating this procedure – several times, if necessary –
enhances the linearization. This procedure is described
on page 1–35.

Installation Instructions
Ambient Conditions
Before you set up your balance, choose a suitable
place which meets the following requirements:
– level, low-vibration weighing table
or a wall console;
– no direct exposure to sunlight, heaters, or similar
sources of heat. This can considerably
increase the temperature inside the draft shield
(greenhouse effect), resulting in incorrect readouts
due to convection currents, turbulence and
buoyancy effects;
– no drafts from open windows or doors;
– avoid brief fluctuations in room temperature.
The balance is not allowed to 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.

Using Verified Balances Approved as
Legal Measuring Instruments in Europe
(only applies to MC5-0CE)
Using Verified Balances as Legal Measuring
Instruments
You must calibrate the balance at the place
of installation before using it as a legal measuring
instrument (see the section entitled “Calibration/
Adjustment” starting on page 1–31).
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.
The legal background for using Sartorius balances
in legal metrology is the EC Council Directive
No. 90/384/EEC for non-automatic weighing
instruments, which has been in effect since
January 1, 1993, within the Internal 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.

1–12
Connecting the Balance to AC Power
The balance is energized by a power supply/AC
adapter. Make sure that the voltage rating printed
on this unit is identical to your local line voltage.
If the voltage specified on the label or the plug design
of the power supply/AC adapter does not match
the rating or standard you use, please contact your
Sartorius office or dealer.
Important Note:
Use only original Sartorius power supplies/AC
adapters. Use of power supplies/AC adapters from
other manufacturers, even if these units have
an approval identification marking from a national
testing laboratory, requires the consent
of an authorized Sartorius service technician.
Detailed information on additional options
for powering the balance is available in our service
information bulletin, no. 15/88 (for example,
using local extra-low voltage).
Plug the cord of the AC adapter/power supply into
the DC jack on the rear panel of the
balance/computing device. Then insert the plug of
the power supply or the AC adapter into a wall outlet.

115 V~
You can select the voltage if you use our portable
power supply (6971172) that has a European-type
plug (rounded prongs).
Safety Precautions
The power supply/AC adapter rated to Class 2 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 data interface (see also “Interfacing Devices”
on page 1–36) is also electrically connected to the
balance housing (ground).
Information on Radio Frequency Interference
Warning!
This equipment generates, uses and can radiate radio
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.

General Instructions for
“Analytical Weighing”
Weighing Electrostatically Charged Samples
and Containers
Major measuring errors can occur when
electrostatically charged samples and containers are
weighed. This problem particularly involves samples
that have an extremely poor electrical conductivity
(glass, plastic, filters) since they can discharge
electrostatic – i.e., friction-induced – charges only
over a relatively long period of time. The result
is an interaction of forces among the charges
adhering to the sample and the stationary components
of the balance (base plate of the weighing chamber,
draft shield construction, balance housing). This
is noticeable when the weight readout drifts. At a
high humidity, this effect is not so pronounced or does
not even occur at all due to the thin layer of water that
condenses on the sample and, through conductive
discharge, counteracts interfering static electricity.
In addition to taking purely mechanical counteractive
measures (protecting the sample using a special
antistatic weighing pan – see the “Accessories”), you
can neutralize the surface charges by “bombarding”
them with ions of the opposite polarity. This
is an extremely effective method of eliminating static
electricity on surfaces (antistatic ionizing blower,
order no. YIB01).
The balance’s environment, including the operator,
can considerably interfere with weighing on account
of static electricity. The balances of the MC Series
have been designed to counteract this phenomenon:
the glass surfaces of the draft shield have a special
metallic coating.
The rear panel of the balance/weighing cell
has a terminal (15) for connecting an equipotential
grounding conductor. It is used for additionally
grounding a peripheral device (for example,
a vibrating spatula). This terminal is designed for
single grounding wires up to .25” standard gauge
or 6 mm2 and for .18” standard gauge or 4 mm2
stranded wires.
1–16
Weighing Magnetic or Magnetizable Samples
It is technically impossible to avoid the use
of magnetizable materials in the manufacture
of balances. Ultimately, the operating principle
of high-resolution balances is based
on electromagnetic force compensation of the load
placed on the weighing pan.
When magnetic or magnetizable samples
or containers (e.g., beaker with a stirrer) are weighed,
interactions among the above-mentioned
components of the balance may occur, distorting
weight readouts.
Unlike deviations caused by electrostatic charges,
magnetic interference is usually constant over
time. However, it is sensitive to and depends on the
position of the sample or container on the
weighing pan and is also characterized by poor
reproducibility.
To reduce the effect described above, we recommend
increasing the distance between the sample and
the weighing pan by using a non-magnetizable
material (the reduction in force is proportional to the
quadrate of the distance). In special cases,
soft-magnetic plates should be used to shield against
interfering magnetic effects.
In the presence of extremely strong magnetic fields –
for instance, when measuring the susceptibility
of a sample in an electromagnet – you should use
the below-balance weighing port which comes
standard on your balance.
1–17
General Instructions for Handling Samples
and Containers
As a general rule, the sample to be weighed should
be conditioned to the temperature of the balance.
This is the only way to avoid air buoyancy errors and
deviations caused by convection currents at the
surface of the sample. Since these effects increase
proportionally to the volume and surface of the
sample, make sure that the size of the tare vessel
selected is in the appropriate proportion to the size
of the sample to be weighed.
Never use your bare hands to touch samples
to be weighed. In addition to the effect on the
temperature, the extremely hygroscopic behavior
of fingerprints left on the sample will cause
considerable interference during weight measurement.
Use forceps or other suitable utensils to place your
sample carefully on the pan.
Working with your balance requires a steady hand
and a smooth, uninterrupted technique.
Perform a few trial weighing operations before you
begin with the actual weighing of your sample
because the temperature in the weighing chamber may
differ from that of the balance’s surrounding
environment, if the weighing chamber has not been
opened for a relatively long period.
When you open the weighing chamber, a change
in temperature will inevitably occur, due to the
laws of physics, and may show up as a change
in the weight readout. In this case, we recommend
that before you begin the actual weighing series you
open and close the weighing chamber at the same
rate as you will be doing during weighing.
After the weighing chamber has been closed, the
weight readout will usually stabilize after about
10 seconds. The accuracy of the weight readout will
increase as you perform successive weighing
procedures with greater consistency.
1–18
Operating the Balance
Balance Display
The display shows the following special codes
for your information:
OFF
The balance was disconnected from AC power
(power failure or outage; the balance was reconnected
to AC power).
O (standby)
The display has been turned off by the e key (31).
The balance is now in the ready-to-operate mode.
b (busy)
Once you have turned on the balance, the b symbol
will be displayed until you press a key.
During operation, this symbol indicates that the
balance processor is still busy processing a function
and will not accept commands to perform any other
functions at this time.
CAL I
The balance has internal calibration weights and
can be calibrated using the f key.
R1 W or R2 W
The number in the R code identifies the particular
weighing range you have selected.
W
Symbol for the application selected (in this case,
the weighing mode and toggling among the
weighing ranges).
Important Note:
If the W symbol flashes, this means that the balance
wants to self-calibrate (see pp. 1–30).
1–19
Turning the Display On and Off (Standby Mode)
Press the e key (31) to turn the display on or off.
Self-Test
After the balance has been turned on, an automatic
self-test of the balance’s electronic circuitry
is performed, and the draft shield closes automatically.
When a zero readout is displayed, the balance
is ready for operation.
Important Note Concerning Verified Balances
Approved for Use as Legal Measuring Instruments
in the E.U.*
For verified balances that have a verification
scale interval “e” which is greater than the scale
interval “d,” and a scale interval “d” ≥ 0.1 mg,
the last digit on the display is bordered.
Automatic Warmup of the Balance Electronics in
MC 210 S, MC 210 P and MC 410 S (-0CE), MC 21 S
Once you have connected the balance to AC power
and turned on the power, the balance’s electronics
automatically begin to warmup. The timer for
warmup is set to 4 minutes. The remaining warmup
time in minutes and seconds is displayed in
a countdown mode.
When the remaining time displayed is less
than one minute, you can interrupt this warmup
procedure by pressing the e key to turn the
balance off and back on again. Following
the self-test and display of a zero readout,
the balance is ready to operate again.
After 4 minutes have elapsed, the balance displays
a zero readout and is then ready to operate.

the European Economic Area
1–20
Opening and Closing the Draft Shield
MC 210 S, MC 210 P or MC 410 S (-0CE):
To load small objects, open the draft shield only
as far as is absolutely necessary for your application.
This reduces the amount of draft so your balance
will stabilize faster than it normally does when the draft
shield is wide open.
You have several options for operating the interior
draft shield door (4):
– Semi-automatically using the l or r key (23)
(max. aperature angle: 170°)
– Using an external foot or hand switch
(see part 5, “Accessories”)
– By a command from an on-line computer
(see part 4, “Interface Description”)
– Fully automatically, e.g., for the functions tare,
calibration, print, etc. (see part 2, “Balance
Operating Menu”)
– With a special display mode while the draft shield
is open (see part 2, “Balance Operating Menu”)
– Manually
Semi-automatic Mode with an Aperture
Angle of 10° to 140°
By a “self-teaching” function, the draft shield door
can “learn” to open automatically to a user-defined
aperture angle between 10° and 140°:
To define this angle, manually move the interior draft
shield door (4) to the desired position.
1–21
Press either l or r to close the draft shield
automatically by motor. While closing, the interior
draft shield door moves slowly. The previously
adjusted aperture angle is stored.
If you press either l or r once again, the draft
shield door will open at a faster speed to the position
you have selected. Press l or r for approx.
2 seconds to open the draft shield door automatically
as far as it will go (170°).
You can always change the aperture angle
by manually adjusting the position of the draft
shield door.
Important Note
The aperture angle remains stored even after you
have turned off the display by pressing e.
A stored aperture setting will not be erased until
you unplug the balance from AC power.
Manual Mode
Of course, you can also open and close the draft
shield door by hand.
1–22
MC 5, SC 2 (-0CE):
You can operate the motorized draft shield (34) in one
of the following ways:
– Semiautomatically using the l or r key (23)
(aperature angle approx. 100°)
– Using an external foot or hand switch
(see part 5, “Accessories”)
– By a command from an on-line computer
(see part 4, “Interface Description”)
– Fully automatically, e.g., for the functions tare,
calibration, print, etc. (see part 2, “Balance
Operating Menu”)
– With a special display mode while the draft shield
is open (see part 2, “Balance Operating Menu”)
– Manually
1–23
Semi-automatic Mode with the Aperture Angle
of Your Choice
To define the aperture angle and the direction in
which the draft shield opens, move the draft shield to
the desired position manually (aperture angle 45°
to 315°).
Press either the l or r key (23) to have the
draft shield closed by motor. The previously adjusted
aperture angle and the direction are stored in
the process.
You can always change the aperture angle by
manually adjusting the position of the draft shield.
You can clear the aperture angle by either
– entering an aperture < 45° using the numeric keys
(e.g., “0”) and confirming this entry by pressing
the l or r key
or
– by closing the draft shield manually
Important Note:
The aperture angle and the direction in which the
draft shield opens remain stored even after you have
turned off the display using the e key.
This information will not be erased until you unplug
the balance from AC power.
1–24
Numeric Entry of an Aperture Angle
The numeric entry of an aperture angle corresponds to
a fixed position. The aperture is measured counterclockwise starting from the closed draft shield position:
– Enter an aperture angle between 45° and 315°
using the numeric keys (20); e.g., 210
– Confirm this entry by pressing either the
l or r key (23), depending on the direction
you wish the draft shield to open
– The aperture angle and the direction are now
stored for further operation
You can clear the aperture angle by either
– entering an aperture < 45° using the numeric
keys (e.g., “0”) and storing this entry by pressing
the l or r key
or
– by closing the draft shield manually
Important Note:
The aperture angle and the direction in which the
draft shield opens remain stored even after you have
turned off the display using the e key. This
information will not be erased until you unplug the
balance from AC power.
Opening and Closing the Draft Shield Manually
Of course, you can also open and close the draft
shield by hand.
!
Important Note:
An open draft shield will always close automatically
if you have not operated the balance for 1 minute.
Exception:
– It will not close automatically if you have set menu
code 8 8 1 “Automatic draft shield function off”
(see part 2, “Balance Operating Menu”)
1–25
Simple Weighing
Place your sample on the weighing pan (7), and close
the draft shield door. Read off the weight indicated
on the display (28) only after the weight unit (“g”, or a
different unit selected – see part 2, “Balance
Operating Menu”) appears as the stability symbol.
Important Note Concerning Verified Balances
of Accuracy Class k
To avoid measuring errors, the respective air density
must be allowed for. The following formula is used to
calculate the mass of the sample:
m = nw
1– ρL/8000 kg m–3
1– ρL/ρ
m = mass of the sample
nw = weight readout
ρL = air density during weighing
ρ = density of the sample
Taring
If you wish to use a container or if the weight display
does not indicate 0.000 mg (depending on the
display mode or weight unit selected), zero the display
before you weigh.
To do so, press t key (26).
During taring, you can have the fully automatic draft
shield function either on or off.
For more information on turning this fully automatic
draft shield function on or off by menu code, refer to
part 2, “Balance Operating Menu.”
Important Note for Verified Balances Approved for
Use as Legal Measuring Instruments:
The small circle in the weight display (on the left)
shows that the balance is exactly tared to “0”
(± 0.25 of a scale interval).

Weighing Range Structure
SuperRange “Single Wide-Range”
(identified by S in the model name MC.....S)
210 g
0.01 mg
SuperRange models have an extraordinarily high
resolution; i.e., the weighing range has a resolution
ranging from 100,000 to a few million digits.
There is one level of fine readability for the entire
weighing range (for example: 0.01 mg).
PolyRange “Multi-Interval”
(identified by P in the model name MC.....P)
210 g
110 g
60 g
0.05 mg
- 0.00 mg -
0.02 mg
0.01 mg
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 or 5 digits.
After you have pressed the tare key (26), you will
obtain the highest possible resolution, even when the
balance is loaded.
1–27
Weighing in the IQ-Mode*
(Load-Dependent Readability)
In the IQ-mode, weighing is done with a loaddependent readability of, e.g., 0.01% (for different
settings, see part 2, “Balance Operating Menu”)
throughout the entire weighing range of the balance.
Oftentimes, a display accuracy of 10 mg
is sufficient for a load of approx. 110 g. In this case,
it makes sense to select weighing range R 1 with
an accuracy of 0.01% by pressing the w key (29).
While you are filling up to a target weight, it is
certainly easier to work with a target of 110.20 g than
with an absolutely accurate readout of 110.19885 g.
* = not with verified models; other settings in
the balance operating menu are necessary
on model MC 5
1–28
Mass Unit Conversion by Toggling
You can have the weight displayed in milligrams
or grams.
To select the weight units one after the other, press the
w key (29) each time.
In addition to milligrams and grams, the standard
balances give you a wide variety of other menudefinable international weight unit options.
For more information, refer to part 2, “Balance
Operating Menu.”

Calibration/Adjustment
and Linearization Functions
During calibration, the span* of your balance
is adjusted to changes in ambient conditions.
Relinearize your balance each time you set it up in
a different area or recalibrate (re-adjust) it when the
ambient conditions change (for example, temperature
or barometric pressure). Even if these conditions are
constant, the balance should be calibrated once
a day. To meet the highest requirements for accurate
weighing, we recommend that you calibrate
the balance before each weighing series or set the
isoCAL self-calibrating function to “ON.”
W : Self-calibrating Function “isoCAL”
The criteria for fully automatic calibration
are as follows:
– Two hours have passed since the balance was
turned on (“cold start”)
– The difference between the current temperature and
the temperature during the last calibration procedure
is greater than ± 1° Kelvin
– (Up to) four hours have passed since the last
automatic calibration
Flashing W Symbol
If the W symbol flashes, the balance wants to selfcalibrate. You do not need to interrupt your weighing
series; the balance will wait until you have unloaded
the weighing pan and have not used the balance for
one minute before performing internal self-calibration.
During this procedure, the draft shield must be closed
to ensure that calibration is done correctly. The
symbol flashes until the balance begins self-calibration
or until you activate one of the calibration functions
manually (see next page).
To turn off the self-calibrating function by menu code,
refer to part 2, “Balance Operating Menu.”
* = The difference between the indication of a weight
at maximum capacity and the indication at zero
1–30
The balance offers you various calibration and
linearization functions.
You can interrupt any calibration or linearization
procedure by pressing the c key (32).
In the fully automatic mode, the draft shield closes
after the f or the t key has been pressed.
!
Important Note:
During calibration or linearization, you must observe
the following:
– Unload the weighing pan
– Do not disconnect the balance from AC power
– Do not unplug the connecting cable

Care and Maintenance
Servicing
Regular servicing by a Sartorius service technician
will extend the service life of your balance. Sartorius
can offer you service contracts with your choice of
regular maintenance intervals ranging from 1 month
to 2 years.
Cleaning the Balance Housing and the Draft Shield
Before cleaning the balance, unplug the power supply
from the wall outlet.
Please do not use any aggressive cleaning agents
(solvents or similar agents). Instead, use a piece of lintfree cloth which has been wet with a mild detergent.
Make sure that no liquid enters the balance housing.
After cleaning, wipe down the balance with a soft, dry
piece of cloth.
To clean the draft shield, remove it from the weighing
cell. Clean the draft shield with a commercially
available glass cleaning agent or in a dishwasher.
Cleaning the Weighing Chamber
Carefully remove spilled powder from underneath
the protective disk (8) by using a small car vacuum
cleaner with a mini-hose attached.
Do not clean the weighing chamber by blowing off
powder from the balance components!
To remove liquid spills, use blotting paper.
Do not insert a pair of forceps or any other object
behind the draft shield closing plate.
Important Note:
The weighing system is hermetically sealed from the
draft shield closing plate area so that dirt cannot enter.
1–40
Safety Precautions
If there is any indication that safe operation of the
balance with the power supply/AC adapter
is no longer warranted, turn off the power and unplug
the equipment from AC power immediately. Lock the
equipment in a secure place to ensure that it cannot
be used for the time being.
Safe operation of the balance with the power
supply/AC adapter is no longer ensured when
– there is visible damage to the power supply
– the power supply no longer functions properly
– the power supply has been stored for a relatively
long period under unfavorable conditions
In this case, notify your nearest Sartorius Service
Center or the International Service Support Unit based
in Goettingen, Germany. Only service technicians
who have access to the required maintenance
manuals are allowed to perform maintenance and
repairwork on the equipment.
We recommend that the balance together
with the power supply be inspected by a qualified
Sartorius service technician according to the
following checklist:
– Insulation resistance > 7 megohms measured
with a constant voltage of at least 500 V at
a 500 kohm load
– Equivalent leakage current < 0.05 mA measured
by a properly calibrated multimeter
The duration and number of measurements should be
determined by a qualified Sartorius service technician
according to the particular ambient and operational
conditions for the power supply. Such inspection
should be done at least once a year.
1–41
Balance Operating Menu
The Sartorius MC 1 Balance can be adjusted to meet your special requirements;
e.g., to weigh in various units of measure, adapt to unfavorable conditions
and process weight data for a variety of applications.
In the operating menu, you can define how your balance will adapt to ambient
conditions, and also how it will work to meet your needs.
The factory-set menu codes are identified by an “*.” You can select the functions not
identified by an “*” by setting the respective menu code.
Important Note Concerning Verified Balances Approved for Use as Legal
Measuring Instruments:
The balance operating menu can also be changed when the balance is being
used as a legal measuring instrument. Codes that are not permitted for operation
of the balance as a legal measuring instrument are blocked or not displayed
as a rule. After verification, the balance operating menu cannot be locked with
the menu access switch (-L- not displayed).
2–1
Changing a Menu Code Setting
To select specific functions, you will need to set the
respective menu code.
There are three steps to changing a code:
– Accessing the menu
– Setting a code
– Confirming and storing this code
For setting menu codes, the keys have special
functions. To set a code, use the four keys which are
defined on the display as arrow points to indicate
the direction:
< w and > p
^ f and v F
t
c
= Move to the left or right
= Increase or decrease a number
by one with each press
= Confirm a code setting
= Store a code setting and exit
the menu
Now try changing the weight unit in the second
weighing range from grams to carats “ct,”
code 3 1 4.
Accessing the Menu (Example Code 3 1 4)
– Turn the balance off
– Turn it back on again
– While all segments are displayed, briefly press the
t key (10).
– If -L- is displayed, unlock the menu as follows:
– Remove the protective cap located on the
left-hand side of the balance’s/electronic computing
device’s rear panel to expose the menu
access switch
– Move the switch in the direction of the arrow
2–2
– Press the f key to change the left-hand number
to “3”
– Press p to move to the middle number
– Now press the p key to move to the right-hand
number (When you move to the right-hand number,
the previously set numeric code will be indicated).
– Press the f key to change the right-hand number
to “4”
Confirm the Code Setting
– You must press the t key in order to confirm
the code you have just set. This is indicated by the
“o” after the code.
– Press c to store the new menu code setting
The current menu code setting in the balance
operating menu is identified by a small “o” after the
last number. When you access the operating menu,
the previously set numeric code will be displayed after
you have selected the left-hand and middle numbers,
which means the entire menu code setting will
be displayed. This makes it easy for you to check
the previously set menu codes.
If you would like to change several menu code
settings, you do not have to press c after each
change to exit the balance operating menu.
2–3
Please do not forget to relock the balance operating
menu. The “-L-” indicates that it is currently locked:
To use the locking function, make sure code 8 1 2
is set in the balance operating menu.
If code 8 1 1 is set, the menu access switch will
not lock.
In this case, “-C-“ will be displayed whenever you
access the menu:
Undoing All Menu Code Changes – Reset Function
The reset function lets you undo all menu code
changes, which means that you will obtain the original
factory-set menu codes indicated by an “*” so that
your balance will operate according to them.
To use this function, you will need to select
o
code 9 – – 1 . See the previous pages for information
on confirming and storing a menu code setting.
The charts on the next pages give just a small
sampling of the code options available for
the balance operating menu. These options include
standard balance operating parameters, utilities
for printouts or data transfer and additional functions.

Display Modes for Standard Balances
You can select the display mode that best meets your individual requirements.
Last Numeral Blanked When the Load Changes
As the load on your balance changes, the display resolution is reduced
by a factor of 10 so that you will obtain a faster and more stable readout.
Once the load has stabilized, the readout is shown again with the full display
accuracy, which means the last numeral is displayed.
Display Accuracy
You can define the level of accuracy by changing the display increments, also
called “scale intervals” (of the last numeral). The display increments possible are
as follows:
1, 2, 5, 10, 20, 50, etc.
Starting with the basic increments of a weight unit, the display accuracy can be
reduced by as many as three levels so that you will obtain a faster readout.
This accuracy is reduced in relation to the selected basic increment of the weight
unit. Example: weight unit “ct” for carats
(5 increments) with code setting 1 8 3 → 10 increments. To make this concept
easier to understand, the three levels are designated as “rounding factors”
in the tables summarizing the various menu code settings.
IQ-Mode
(Load-Dependent Readability)
In the IQ-mode, weighing is done with a menu-definable, load-dependent
readability throughout the entire weighing range of your balance. In the process,
the display resolution of the last digit of the weight readout changes in increments
of 1, 2, 5, 10, 20, etc., in proportion to the weight of the sample.
This mode for adapting the display accuracy enables you to weigh with a constant
relative accuracy between 1% and 0.01% over the entire weighing range
of your balance. Select the load-dependent display accuracy independently for
each of the three weighing ranges. The accuracy selected is shown in the top
right-hand corner of the application display field.
2–11
PolyRange Function (application for single-range balances)
The PolyRange function divides a single 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 digits = only the next to the last numeral
of the readout will change; the last numeral is blanked).
The PolyRange function makes filling easier because the readability becomes
slightly coarser as the load increases and you will not immediately lose an entire
place of readability.
Press the tare key at any range level to restore the full resolution of the first range,
even when the balance is loaded.

For example, an “N” printed or displayed before a weight value identifies
it as a net weight. If you set the code for “without data ID code,” only net weights,
results in percent, and counting results will be output. The ID code increases the
data output format from 16 to 22 characters for each weight readout.

Depending on the operating mode – line current, battery operation
or continuous operation – you can change the power-on mode of your balance.
The factory setting is: (power) off —> on <—> standby.
In the setting “toggle between on and standby,” the balance power will
turn back on automatically after a power failure has occurred, or after you have
disconnected your balance temporarily from line current.
In the setting “automatic power-on,” the balance will turn back on automatically
after a power failure has occurred or after the balance has been disconnected,
then reconnected to line current. In this setting, the balance can no longer
be turned off by the e key.

Fully Automatic Draft Shield Function
You can define the fully automatic draft shield function to meet the most diverse
requirements. After you have pressed a function key (or after a control command
has been received – see part 4, “Interface Description”), the draft shield will close
automatically and the balance will then perform the particular function activated
by the key. If code 8 8 2 or 8 8 3 is set, the draft shield will open once the
function selected has been performed. In addition, when codes 8 8 2 through
8 8 5 are set, the draft shield closes automatically if the balance has not been
used for more than one minute.
To be on the safe side for automatic operation of the balance with a robot, you
should turn off the fully automatic draft shield function (code 8 8 1).
The draft shield status should always be polled for operation with a robot
(see part 4, “Interface Description”).
The draft shield operates automatically for the following functions:
– powering on the balance (e key)
– taring once the balance has stabilized (t key)
– printing on request after stability (p key)
– starting all calibration functions (f key)
– using the tare memory once the balance has stabilized (f key) –
see also part 3, “Application Programs”
– storing weights during differential weighing and backweighing, weighing in
percent and counting (F key) – see also part 3, “Application Programs”

compliance with ISO, GLP, GMP and EN, etc.
The balance can record all completed calibration/adjustment operations and
output data in compliance with the requirements of Good Laboratory Practice (GLP)
and ISO. The balance, interfaced with a data printer or a computer, creates
a document that records the date, time, serial number and model number, making
it possible to clearly trace data to the balance that generated it and the time
at which it was generated.
Select the ISO/GLP printout / record mode by setting the respective code
in the balance operating menu.

Application Programs
In addition to the functions implemented strictly for weighing, Sartorius MC

Changing the Density of a Sample
Enter the density of a sample using the numeric keys and then confirm this value
by pressing the F key identified by “STO.” Afterwards, the density that you
entered will be shown in the application display. This density is used to calculate
the absolute mass of the sample on the balance.
The density must be entered in grams per cubic centimeter (g/cm3). A density
may not be greater than 22.5 g/cm3 or less than 0.1 g/cm3. The density that you
enter will be stored in the non-volatile memory.
Recalling a Stored Density
You can recall the density that you last used by pressing the F key identified
in the display by “STO.”
Press the w key at any time to toggle between weight and mass.
Air Buoyancy Correction after an Air Density Determination
A special function makes it possible to determine and store the air density (for more
information see p. 3–9). The density can be between 1.0 kg/m3 and 1.4 kg/m3.
If the air density determined deviates from the standard value of 1.2 kg/m3,
the F key normally identified by STO is shown as STO ●.
Use in Combination with Other Programs
The air buoyancy correction program can be used in combination with
other application programs. This means you will have all functions of the
combined program available in addition.

Air Density Determination
For highly precise analyses, the balance offers you a function with which
fluctuations in the air density can be determined.
!
The air density at the place you set up your balance can be determined
within the range of 1.0 kg/m3 and 1.4 kg/m3.
For determining the air density, use the special weight set which is available
as an accessory (see also part 5, “Accessories”). This weight set consists of one
steel and one aluminum weight. Their exact mass values are specified on
a certificate, which is included with the set. By a differential weighing method, the
air density is determined using the two weights.
To access this function, set the appropriate code in the balance operating menu:

Activating the Air Density Determination Function
Hold down the tare key for more than 2 seconds until
“C.I.” and “CAL” are displayed next to the f key.
To activate the air density determination function,
press F, identified by “v,” several times until “A.d.”
is displayed.
“A.d.” stands for “air density.”
Unload the weighing pan and tare the balance.
Starting Air Density Determination
To start air density determination, press the f key
when the display shows a zero readout. Afterwards,
a weight for steel “St” is displayed.
”Err 02”:
Interrupt
procedure:
The effects of an external disturbance
can cause the error code “Err 02” to
be displayed briefly. If this occurs,
tare the balance and then press the f
key again when the display shows
a zero readout.
You can stop an air density
determination procedure
at any time:
– By pressing the c key so that
a previously stored air density
is not changed or
– By pressing F identified in the
display by “RES” to set the standard
air density 1.2 kg/m3
3–11
Using the Weight Set for Air Density Determination
– Steel Weight –
Use the numeric keys to enter the exact mass value
specified for the certified steel weight
(e.g. 4.999990) and store this value by
pressing the f key identified in the display by “STO.”
If you press f, identified by “STO,” without
making a numeric entry, the display changes
to the density readout. Now you can
change it for a special steel weight. Enter
the mass value and press f to define
this density.
Center the steel weight on the weighing pan and close
the draft shield.
After the steel weight has been confirmed, the display
will show a zero readout. Now, remove the steel
weight from the weighing pan and close the
draft shield. Afterwards, if the value for the aluminum
weight “Al” is displayed, you can continue with
the procedure.
”Err 03”: The effects of an external disturbance
can cause the error code “Err 03”
to be displayed briefly. If this occurs, restart
the air density determination procedure.
3–12
– Aluminium Weight –
Use the numeric keys to enter the exact mass value
specified for the certified aluminum weight
(e.g., 5.018072), and store this value by
pressing the f key identified in the display by “STO.”
If you press f, identified by “STO,” without
making a numeric entry, the display
changes to the density readout. Now you
can change it for a special aluminum weight.
Enter the mass value and press f to define
this density.
Center the aluminum weight on the weighing pan and
close the draft shield.
After the aluminum weight has been confirmed,
the calculated air density between 1.1 kg/m3 and
1.3 kg/m3 will be displayed.
If the air density determination result is
a value which is not between 1.0 kg/m3 and
1.4 kg/m3, the determination procedure
is interrupted with two beeps and the
previous air density remains stored. If this
occurs, restart the air density determination
procedure after the two beeps.
Storing the Air Density and Ending the Procedure
– Store the air density displayed by pressing the
F key identified by “STO” or
– Reset the display to the standard value 1.2 kg/m3
with the c key and store this value by pressing
the F key identified by “STO”
An acoustic signal indicates the end of the air density
determination procedure.

Differential Weighing and Backweighing
Differential Weighing and Backweighing
Code 2 1 6
Symbol displayed: % S
The purpose of this application is to weigh a certain sample in original condition
and then after treatment, such as drying, to determine the difference between
the two weights and the remaining sample quantity. This is done either in percent
or in a weight unit.
For each sample, the net weights are compared with each other, since the tare
weights are stored first and later subtracted. Tare weighing can be
de-activated, if a container will not be used in the treatment process. There
are memory locations for a maximum of 50 samples.
Backweighing, which means weighing a sample after a chemical or thermal
reaction, can be done in any sequence (known as “random” backweighing).
It is also possible to perform several backweighing operations. In this case, each
backweighing operation is done in reference to the original sample
weight (= 100%).
Therefore, the usual sequence of the weighing operations is as follows: tare
weighing - weighing-in - backweighing. This sequence can be performed
according to the individual or combined weighing mode.
!
3–14
Charging the Battery for Data Storage
It goes without saying that the data are stored in a battery-backed
memory. When the balance is unplugged from AC power, the
data generated will remain stored for approximately three months.
In the standby mode, the data are retained by the internal power
supply. The rechargeable battery can also become discharged
after relatively long periods of storage. In this case, or for initial startup,
leave the balance connected to AC power for about 12 hours to
charge the battery.
Weighing Sequence
Individual or Combined Weighing Mode
Individual Weighing Mode

In the individual weighing mode, the weights are stored in the following sequence:
– Tare weighing – weighing-in – backweighing
– If necessary, selection of an available memory location
– Tare weighing – weighing-in – backweighing...
The data of a sample in a memory location are overwritten until a new memory
location is selected.
In the consecutive individual weighing mode, the weights are stored in this sequence:
– Tare weighing – weighing-in – backweighing
– Automatic selection of the next memory location
– Tare weighing – weighing-in – backweighing...
Beginning at a specific memory location, the memory locations that follow
are selected automatically using the F key. It is also possible to switch to a new
memory location using the numeric keys and the F key.
Combined Weighing Mode

In the combined weighing mode, the values are stored in the following sequence:
– Tare weighing – weighing-in – tare weighing – weighing-in...
Backweighing is done only after all of these operations have been completed.

After each weighing-in operation has been completed, the next memory location
is automatically selected. To proceed from weighing-in to backweighing, you must
select the corresponding memory location ID by entering the appropriate number
and pressing the F key.

The calculated value is locked into the display once the sample residue has been
stored. To “unlock” this readout, press RE S v - F or select a different memory
location using the numeric keys and F. Afterwards, you can proceed with the
next tare weighing.
A stored value of a backweighed sample can be overwritten with a current value
anytime after the corresponding memory location has been selected. To do this,
press c. A backweighing operation is done in reference to the original sample
weight (= 100%).
Once you have completed processing or treatment of a series of samples, you can
select another memory location using the numeric keys. Therefore, you can
perform backweighing in any sequence (known as “random backweighing”). In
the consecutive individual weighing mode, the next memory location is
automatically selected using the RE S v - F key after backweighing (code 3 6 2).

Important Note for Verified Balances Approved for Use as
Legal Measuring Instruments:
You may not use the calculated value when the balance is being used
as a legal measuring instrument. The display symbol “R2” flashes to identify nonverified weights (not legal for trade).
De-activating the Differential Weighing and Backweighing Program during
a Weighing Procedure (“Standard Weighing Mode”)
To turn off the differential weighing and backweighing program function, press w.
The function keys will now be blocked and the identification symbols will no longer
be displayed.
Blocking the function keys ensures that the values you have stored will not be erased
by another operator or calculated based on an incorrectly entered backweighed
sample quantity, especially if you do not perform the differential weighing steps
immediately in succession. This allows you to weigh in the standard mode and
print weights in the meantime without affecting your other results.
Important Note:
If you turn off the differential weighing and backweighing program after tare
weighing, you will have to store the respective tare value again.
Clearing the Memory
How to delete data stored in individual memory locations:
– Select the respective memory location using the numeric keys and F
– Hold down the c key for more than 2 seconds
How to delete the entire memory contents:
– Hold down the i key for more than 2 seconds
– When “CLEArALL” is displayed, press STO - F
The entire memory contents will now be cleared and the clear function terminated.
If you do not wish to clear the entire memory, you can interrupt this procedure
by pressing c when “CLEArALL” is displayed.
!
Caution!
If you press F when “CLEArALL” is displayed, all data stored
in the memory will be deleted.

– Buoyancy method
– Specific gravity bottle method
The Achimedean principle is applied to determine the volume of a particular
sample; this volume is necessary for calculating the density.
Methods
Buoyancy Method
Specific Gravity
Bottle Method
To measure the density inside the weighing chamber
(toploading configuration), use the YDK 01 (-0D).
The method using a specific gravity bottle is suitable

Diameter Determination
Code 2 1 7
Symbol displayed: ◆
Key identified by: STO - F
The diameter determination program offers an accurate solution to the problem
of determining the diameter of wires and metal filaments. To do this, you only need
to enter the density of the object to be weighed in the parameter mode and
the length of the object, using the numeric keys and F. The factory-set density
is the density of steel (8 g/cm3).
Changing the Density of the Object to Be Weighed
You must enter the density in grams per cubic centimeter (g/cm3).
A density may not be greater than 22.5 g/cm3 or less than 0.1 g/cm3.
To select the parameter mode:
To change the setting:
To store the value
(in the non-volatile memory):
– Hold down i for more than 2 seconds
– Enter a numeric value
– Press STO - F
Entering the Length of the Object to Be Weighed
Use the numeric keys to enter the length in millimeters of the object to be weighed,
and then store this value by pressing the F key identified on the display
by “STO.” Afterwards, the diameter in millimeters is calculated and displayed.
Press w to toggle between the diameter determination program and the standard
weighing mode.
Use in Combination with Other Programs
The diameter determination program can be used in combination with other
application programs. This means that you will have all functions of the combined
program available in addition.

Code 2 2 2
Symbol displayed when a value is stored: Net
Key identified by: TAR - f
Press the f key identified by “TAR” to accept and store a weight on the pan
or a numeric entry as a tare weight (this procedure is indicated by “Net” on the
display). The balance is now tared automatically so you can weigh again starting
with a zero readout.
If you have stored a value in the tare memory, a “1” will be printed or output after
the ID of this value to identify it as such on the printout or on the computer screen.
By selecting the appropriate menu code, you can have the tare weight “T1” or
“PT1” instead of the net weight or value “N1” automatically output via the interface
once you have stored it with f identified on the display by “TAR.”
If you combine the tare memory function with another program and have stored
a value in the tare memory, a “1” will be printed or output after the ID of this value
to identify it as such on the printout or on the computer screen.
Use in Combination with Other Programs
The tare memory program can be used in combination with other application
programs. This means that you will have all functions of the combined program
available in addition.

Weighing in Percent
Weighing in Percent
Code 2 1 5
Symbol displayed: %
Key identified by: STO
REF - F
This application program enables you to obtain weight readouts in percent which
are based on a reference weight “Wxx%.”
You can store a weight as a reference percentage “pRef” using the F key,
identified by “STO REF,” in the following ways:
– Place a reference sample on the pan and press the function key identified
by “STO REF” to have the reference weight for 100% calculated from the sample
weight on the pan “Wxx%” and from the reference percentage “pRef” (shown
on the application display).
– Enter a reference percentage “pRef” using the numeric keys and store it with the
function key identified by “STO REF” to have the reference weight for 100%
calculated based on the percentage entered and on a weight on the pan.
To change the standard percentage (value shown on the application display),
either access the parameter mode or enter a different number using the
numeric keys (see page 3–49). You can read the reference percentage in the
application display as long as you have not yet stored the reference weight.
Use w to toggle between percent and weight readouts.
Important Note for Verified Balances Approved for Use as
Legal Measuring Instruments in the EU:*
You may not convert a weight into a percent when the balance is being used
as a legal measuring instrument. The display symbol “R2” flashes to identify nonverified display readouts (not legal for trade).

Over/Under Checkweighing 1)
This program is used to check whether products are within a specific tolerance
range, to sort and classify items, and to fill and batch products. Symbols are
displayed above the bar graph as visual aids for this type of program: the equal
sign indicates the target weight; the minus sign, the underweight limit; and the
plus sign, the overweight limit.
Within the tolerance range, the response sensitivity of the bar graph is increased.
You can define the tolerance limits between 0.1% and 10% as required.
To find these setting options, see the chart on page 3–53. The factory setting
is for tolerance limits of +/–1.0%.

For checkweighing, you can choose between two programs:
– checking net weights
– code 2 2 3
– checking variations in weight – code 2 2 4
To store a weight readout as the target weight, press f identified by “STO.”
This value can be a numeric entry or an ideal sample weight actually on the pan.
The target weight is shown in the analog display as a bar graph. The last segment
of this bar graph ends exactly below the equal sign of the checkweighing
indication. If the weight of a product is “acceptable,” the last segment of the bar
graph will be within the tolerance range of the checkweighing indication.

“Acceptable” values can be printed out or transferred automatically.
Data are output once the readout has stabilized within the tolerance limits selected.
Following data output, this function is blocked until the balance is unloaded to the
extent that the weight on the pan is below the lower threshold limit, or is loaded
so that the weight exceeds the upper threshold limit. The lower weight limit
is approx. 30% and the upper weight limit is approx. 170% of the target weight.

Activation of the Data Output Port Lines
You can have different data output port lines – provided by the balance interface –
activated according to your requirements by setting the appropriate menu
code listed below.
For filling, the port lines can be activated regardless of stability. However, for
standard checkweighing applications, the port lines should be activated only
at stability. This increases the reading speed for an externally connected
checkweighing display (YRD 10 Z).
The checkweighing range is within approx. 30% and 170% of the target weight.
Activate the port lines as follows:

based on a reference sample weight identified by “wRef.”
You can store a reference sample weight and assign it to a reference sample
quantity “nRef” in one of the following ways using F, identified in the display
by “STO REF”:
– Place a sample on the pan and press the function key identified by “STO REF”
to have the reference sample weight “wRef” calculated from the sample weight
and the reference sample quantity (piece count) “nRef” shown on the
application display
or
– Enter the reference sample quantity “nRef” using the numeric keys and store
it with the function key identified by “STO REF” to have the reference weight
“wRef” calculated based on this sample quantity and the sample weight
The reference sample quantity selected will be indicated on the application display
as long as you have not yet stored the reference sample weight.
To change the standard reference sample quantity, either access the parameter
mode or enter a different number and store it by pressing F identified by
“STO REF” (see page 3–58).
To toggle between the piece count and the weight readout, press the toggle key
labeled w.
3–55
Updating the Reference Sample Accuracy
While counting (piece count readout), you can press F identified by “OPT”
to update the reference sample for optimizing the accuracy (approx. double the
reference sample quantity). In the process, the reference weight (average
piece weight) is recalculated based on the total reference sample weight and the
piece count displayed.
It makes sense to update the reference sample accuracy when the weight of the
reference sample quantity is lighter than 100 digits. In this case, double the quantity
of parts before you update the sample weight. You can repeat the updating
procedure as often as desired.

Interface Description
This description has been written for users who wish
to connect their Sartorius MC balance to a computer
or a different peripheral device via the balance’s
standard V24/V28 RS-232C(-S)*)/423 interface.
By using an on-line computer, you can change,
activate and monitor the functions of the balance and
the application programs.
In addition, you can plug an external, universal
remote-control switch into the data interface port
to activate these functions: print (data transfer),
open/close the draft shield, f or F key function,
or tare.
The data interface also provides data output port lines
for various application programs.
If you interface an original Sartorius accessory
device, such as a Sartorius Data Printer or
a similar unit, with a balance that has the factory-set
menu codes, you do not need to change
any settings.

If the weighing system has not stabilized, no unit symbol is output.
For the display format parameter “last numeral off or only at stability” (blank last
numeral by a rounding factor of 10 or display last numeral when the readout
is stable), the 10th character in the string is a space. The reason: the last numeral
without a decimal point is not blanked. Instead, it is given a definite zero,
otherwise the display would go completely blank when the balance is unloaded.
In this case, you will obtain the standard display format.

Data Input Formats
Commands can be input via the balance interface port to control the balance
and application program functions.
Control commands are distinguished according to those with upper-case letters,
or special characters, and those with lower-case letters.
Format for Control Commands
Control commands can include up to 13 characters.
Each character must be transmitted with a start bit, a 7-bit ASCII-coded character,
a parity bit and one or two stop bits.
You can define the parity, baud rate and handshake mode,
including the number of stop bits, by programming the codes in the
balance operating menu (see page 4–16).

“Control Error”
The control code for “control error” is output if the draft shield door has not reached
the selected position after one attempt (for mechanical reasons).
yyy = Turning Angle of the Draft Shield
The movements of the motorized draft shield
door are output as a 3-place decimal number
with a position readout. The readout 000 to
approx. 360 corresponds to the absolute,
counterclockwise position 0° to 360°.
Example: W 008210

Synchronization and Data Output Parameters
Definition
During data communication between the balance and an on-line device
(computer), “telegram-style” information consisting of ASCII characters is transmitted
by the interface.
For error-free data communication, the interface parameters including the
baud rate, parity and handshake mode, as well as the character format, must
be the same for both units.
You can change these parameters in the balance operating menu so that they
match those of the on-line device.
In addition to these parameter settings, you can define the data output parameter
of the balance so that data are transmitted depending on various conditions –
for more information, see part 2, “Utilities” starting on page 2–18.
If you do not plug a peripheral device into the interface port on the balance,
this will not generate an error message. In this case, data will be output but not
received.
Handshake
The balance interface (Sartorius Balance Interface = SBI) has a 23-byte
transmit buffer and a 40-byte receive buffer.
You can access the balance operating menu to define various
handshake parameters:
Software handshake: controlled by “XOFF” and “XON”
Hardware handshake: – after “CTS” send 2 characters
– after “CTS” send 1 character
What happens when you define a software handshake?
Receiving device:
“XOFF” will not be transmitted until the receive buffer has stored the 26th character.
The enable command “XON” is given after the buffer has transmitted all
characters up to the 14th character.
4–13
If the device addressed does not understand the control command, the SBI
receiving device continues to operate additionally with a hardware handshake
after it has received another 6 characters.
For data communication with a software handshake, “XON” must be sent
by a device when it is turned on in order to enable another on-line device
to exchange data.
Sequence:
Transmitting

– – – – – byte – – – – →
– – – – – byte – – – – →
– – ← – – – <XOFF> – – – – –

(Once XOFF has been transmitted, a maximum
– – – – – byte – – – – →
of 14 bytes can still be received.)

Pause

:
:
:
:
– – ← – – – <XON> – – – – – –
– – – – – byte – – – – →
– – – – – byte – – – – →
Transmitting device:
The importance of handshake control for data transmission becomes
especially apparent
– when the continuous automatic data output parameter is defined
– when data output is controlled by application programs
Once <XOFF> has been received, it prevents further transmission of characters.
When <XON> is received, it re-enables the transmitting device to send data.
The transmitting device is always enabled for sending data after it has been
switched on.
If data transmission is interrupted by the control line (CTS) or the command <XOFF>
while a data block is being output from an application program (only for printing
a section of text with several lines of data), the readout will be locked into the
display at the same time.
Data output will be blocked until the interface receives an enabling signal.
4–14
Activating a Data Output Process
You can define the data output parameter so that output is activated either
automatically, or when a print command is received. You have two options for the
automatic mode: data output can be either synchronous with the balance display
or activated at defined intervals (to select the parameter, see part 2, “Utilities”).
Data Output by Print Command
The print command can be transmitted by a software command or by pressing the
print key.
You can connect an external universal switch for remote control to the balance
interface port in addition to an interface cable for a different device. For the switch,
use pins 8 and 15 of this port and a cable up to 1.5 m or 5 ft. long.
If data output is requested by a software command (see the section on “Data Input
Formats”), you can install a 15 m (50 ft.) cable for RS-232C or a 300 m (984 ft.)
cable for RS-423.
Automatic Data Output
In the “auto print” operating mode, the data are output to the interface port without
requiring a print command. You can choose to have data output automatically at
defined print intervals with or without the stability parameter. Whichever parameter
you choose, the data will be output as the readouts appear on the balance display.
If you select the auto print setting, data will be transmitted immediately the moment
you turn on the balance. Automatic data output can be stopped and restarted
either when you press the print key, or when an external print command is received,
if you have set menu code 6 2 1.
These data output functions are described in part 2, “Utilities.”

Special Interface Functions
Data Input/Output to/from the Female Interface Connector
You can plug an external switch for remote control into the female interface
connector (such as foot switch YPE 01 RC with the three functions ”open/close
draft shield,” ”tare” and “print” [factory setting]).
If you change the menu code setting, you can interface both a checkweighing
display (such as our color-coded YRD11Z for OVER/UNDER checkweighing)
and our universal remote-control switch to your balance.

Declarations of Conformity
The C Mark on Sartorius Equipment
In 1985, the Council of the European Community
approved a resolution concerning a new approach to
the technical harmonization and standardization of
national regulations. The organization for monitoring
compliance with the directives and standards
concerning C marking is governed in the individual
EU Member States through the implementation of the
EC Directives adopted by the respective national
laws. As of December 1993, the scope of validity for
all EC Directives has been extended to the Member
States of the European Union and the Signatories
of the Agreement on the European Economic Area.
Sartorius complies with the EC Directives and
European Standards in order to supply its customers
with weighing instruments that feature the latest
advanced technology and provide many years of
trouble-free service.
The C mark may be affixed only to weighing
instruments and associated equipment that comply
with the following Directive:
Council Directive 89/336/EEC
“Electromagnetic Compatibility (EMC)”
This Directive regulates the use of equipment that can
cause electromagnetic interference or whose
functioning can be influenced by such interference.
Applicable European Standards:
Limitation
of emissions
EN 50081-1
EN 50081-2
Defined
immunity
to interference
EN 50082-1
EN 50082-2

Important Note:
The operator shall be responsible for any
modifications to Sartorius equipment and for any
connections of cables or equipment not supplied
by Sartorius and must check and, if necessary,
correct these modifications and connections.
On request, Sartorius will provide information on the
minimum operating specifications (in accordance
with the Standards listed above for defined immunity
to interference).
Additional Directive for Weighing Instruments Used
in Legal Metrology:
Council Directive 90/384/EEC “Non-Automatic
Weighing Instruments”
This Directive regulates mass determination in legal
metrological applications, e.g., in
– the manufacture of pharmaceuticals
– medicine and health care
– calculation of fees
– price calculation
For the respective Declaration of Type Conformity
for weighing instruments approved for use as legal
measuring instruments with an EC Type-Approval
Certificate, see page 6–4.
This Directive also regulates the performance
of the EC verification by the manufacturer, provided
that an EC Type-Approval Certificate has been issued
(see page 5–5) and the manufacturer has been
accredited by an officer of a Notified Body registered
at the Commission of the European Community
for performing such verification.
On February 15, 1993, Sartorius AG received
accreditation for performing verification.
For information on the C mark on Sartorius equipment
and legal regulations currently applicable in your
country, and to obtain the names of the persons to
contact, please ask your local Sartorius office, dealer
or service center.

Adjusting the External Draft Shield Element on MC 210 S,
MC 210 P and MC 410 (-0CE)
The draft shield consists of two semicylindrical elements.
Grasp the lower riffled part of the element to turn it to the
position you desire.
In addition, you can move the swivel-mounted display
to the position you desire (+/– 85°).
Adjusting the Aperture Angle of the Draft Shield
A narrow aperture angle will reduce the effects of drafts,
allowing the balance readout to stabilize faster.
To define the aperture angle, manually adjust the draft
shield door to the opening position you desire. Press r or l
to close the draft shield automatically.
This stores the aperture angle you have just adjusted.
Press r or l again, and the draft shield will now open
to the position you selected.

Air Density Determination
For highly precise analyses, the balance offers you
a function with which fluctuations in the air density can
be determined. During the “EUREKA” air buoyancy
correction program, the air density is used to automatically
calculate the true mass (weight) of the sample/object
being weighed. For determining air density, use the
special weight set which is available as an accessory.
This weight set consists of one steel and one aluminum
weight. Via a differential method, the air density
is determined with the two weights.

Fully Automatic Draft Shield
You can define the fully automatic draft shield function
to meet the most diverse requirements to combine work
procedures and make them easier. After you have
pressed a function key or after a control command has
been received, the draft shield will close automatically,
and the balance will then perform the particular function
activated by the key. If code 8 8 2 or 8 8 3 is set,
the draft shield will open once the function selected has
been performed.
