Installation Instructions

Ambient Conditions

Unfavourable ambient conditions may affect the weight readouts.
Therefore, choose a suitable place to set u p your balance. lt should not be ex­posed to the following:

—

Extreme heat radiation

—

Drafts

—

Extreme- vibrations

—

Aggressive chemical atmospheres

Set up your balance on a sturdy fable or on a wall console (see "Accessories" in
"Part l): Product Data Sheet").

Do not expose the balance to extreme moisture over long pe rio d s. Mo isture in the
air can condense on the surfaces of a cold balance whenever it is brought to a
substantially warmer place. lf 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 specific requirements and to the ambient con­ditions simply by changing the code settings in the balance operating menu. For
more information, t urn to "Part III: Balance Operating Menu."

8

Getting Started

Place the components listed below inside the weighing chamber one at a time in
the Order given:

- shield disk (8)

- weighing pan (7)

- protective ring (6)

- interior weighing chamber draft shield (depending on the balance model) (5)

Place the small draft shield cover (2) on top of the semi cylindrical interior draft
shield door (4).

Adjusting the Exterior Draft Shield Element

The draft shield consists of two semi cylindrical dements, one of which functions as
a door. Turn the exterior draft shield element (3) by the riffled part on the bottom
to the position you desire, That way, you will have the opening located exactly
where it is most convenient for you. When adjusting the exterior element, be sure
to shield the weighing chamber from you r breath and the warmth of your hands
(see diagram on the left in addition).
Depending on your application, you can define the menu code so that the inferior
draft shield door (4) is opened by motor or by hand (see pp. 14).

Adjusting the Swivel-Mounted Display Unit

Move the swivel-mounted display unit (11) around the base of the draft shield to
adjust it to the position you desire (+/- 85°).

9

Connecting the Balance to Line Voltage

The balance is energized by a power supply. Make sure that the voltage rating
printed o n this unit is identical to your local line voltage .
lf the voltage specified on the label or the plug design of the power supply does
not match the rating or Standard you use, please contact your Sartorius Office or
dealer.
The power supply is suitable for installation as stationary equipment. To use a
main feeder cable from the ceiling or to mount a CEE plug, you will have to make
arrangements inside your facilities for installation of such cable equipment by a
certified electrician.

Important Note
Use only original Sartorius Power Supplies identified by the Sartorius label. Use of
power supplies 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.
To operate your balance using an external rechargeable battery, pack, see "Ac­cessories" in "Part II: Product Data Sheet.".
Detailed information on additional options for powering the balance is available
in our Service Information bulletin, no. 15/88 (fore example, using local! extra­low voltage).

Plug the cord of the power supply into the AC jack on the balance, Then insert the
plug of the power supply in a wall outlet.

10

Safety Precautions

The power supply 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 ca n b e grounded for Operation.

The interface (see "Interfacing Devices" on page 28 in addition) is also electrically
connected to the balance housing (ground).

Information on Rad io-Frequency Interfere nce:

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 this own expense will be required .to take
whatever measures may be required to correct the interference.

Connecting Electronic Devices (Peripherals)

Make sure to unplug the balance from the power
supply before you connect or disconnect a
peripheral device (printer or PC) to or from the
interface port. Safety Precautions

11

Information on Weighing Electro statically 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. In addition, the glass draft shield interior has a conductive coat­ing.

There is a terminal (15) for connecting an equipote ntial g ro unding conductor to
the frame (housing) on the rear side of the balance. This is used for additionally
grounding a peripheral device connected to the balance (for example, a vibrating
spatula). The terminal is designed for single grounding wires up to .25" Standard
gauge or 6 mm

2

- and for .18" Standard gauge or 4 mm2 stranded wires.

lf you need to use electro statically charged glass or plastic Container s with a rela­tively large diamet er, you should utilize our antist a t ic pan (155 mm – see "Acce s ­sories" in "Part II: Product Data Sheet").

Levelling the Balance Using the Level Indicator

At the point of use, level the balance using the levelling feet (9) so t hat the air
bubble is centered within the circle of the level indicator (10).

To level the balance .using the level Indicator as a guide:
Extend the levelling feet (turn clockwise) to lift the balance.
Retract the feet (turn counter clockwise) to lower the balance.

12

How to Operate the Balance

After initially connecting the balance to line power (or after a relatively
long power outage), allow for at least 2 hours' warmup.

Working with the Research Series Balance requires a smooth, uninterrupted tech­nique.

The weight display shows the following special codes for your information:

OFF
The balance was disconnects from line power (power failure or outage; the bal­ance was reconnected to line power).

0 (standby)
The display has been turned off by the

key (27), and the balance is now in the

ready-to-operate mode and does not require warmup.

(busy)

Once you turn on the balance, the

symbol is displayed until you press a key.
During Operation, this symbol indicates that the balance processor is still busy
processing s function and will not accept any other commands to perform func­tions at this time.

CAL
I
The balance has internal calibration weights and can be calibrated with the
key (for the "Quick-CAL” function, see also page 22).

, R1 or R2
The number in the R code identifies the particular weighing range you have se­lected.

Symbol for the application selected (in this case, the weighing mode and toggling
among the weighing ranges).

13

Important Note
lf the

symbol flashes, this means that the balance wants to self-calibrate. You
do not need to interrupt your weighing procedure, because the balance will wait
until it detects that you have stopped weighing for one complete minute.
Afterwards, the balance will perform fully automatic infernal calibration. The
symbol will flash until the balance Starts this fully automatic procedure on its own
or until you activate one of the calibration functions by pressing a key (see p p.

22).

Turning the Display On and Off (Standby Mode)

Press the

key (27) 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.
It ends with a readout of "0.00000 g" or "0.0000 g" ( depending on your b a l­ance model or the display mode selected).

Important Note for Automatic Operation with a Robot

To be on the safe side for automatic Operation of the -balance with a robot, you
should turn off the full y a utomatic draft shield functi on (see "Part III: Balance Op ­erating Menu"). Otherwise, if a power outage occurs and the balance is auto­matically restarted, the robot arm may accidentally hit the draft shield as it is clos­ing.

14

Opening and Closing the Draft Shield Door

If you are loading 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
would when the draft shield is wide-open.

You have several options for operating the interior draft shield door (4):

– Semi-Automatic Mode (Aperture Angle s 170°) –

Press one of the keys labeled

(22) to have the draft shield door opened or
closed by motor.
The interior draft shield door moves slowly the first time it is opene d after connect­ing the balance to AC power.

– Semi-Automatic 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-define d aperture angle from 10° to 140°:
To define this angle, move the interior draft shield door (4) to the desire d Po sitio n.

15

Press the

key (22] to have the draft shield door closed by motor.

While closing, the door moves slowly. The previously adjusted aperture angle is
stored in the process.

Now if you press the

key (22) again, the draft shield door will open at a faster

speed to the Position you selected.

You can load and remove a tare container with a diameter exceeding the aper­ture angle, without having to change the stored aperture setting. To do
so, press the

key (22) for approx. 2 seconds.
This will cause the draft shield door to open 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.
lf you want the draft shield door (4) to open completely (170° C) after you p re s s
the

key, just open the door manually as far as it will go.

Important Note

The aperture angle remains stored even after you have turned off the display u
sing the

key.
A stored aperture setting will not be erased until you unplug the balance from AC
current.

– Manual Mode –

Of course, you can also open and dose the draft shield door (4) by hand.

16

Weighing

Place your sample on the weighing pan (7) to determine the weight, and dose the
draft shield door (for example, by pressing the

key (22). Do not read off the
weight indicated in the display (18) until the weight unit (in this case “g” or a dif­ferent unit selected - see "Part III: Balance Operating Menu"} appears as the sta­bility symbol.

Taring

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

0.00000 g or 0.0000 g (depe n d i ng on the particular bal a n ce model you are us ­ing, or on the display mode selected), zero the display before You weigh.

To do so, press the tare control

(24).

During taring, you can have the fully automatic draft shield function either on or
off. To shorten work procedures; and make them easier, you should have this fully
automatic function o n active Status. In this case, after you press the tare control,
the draft shield door will dose, the balance will be tared, and the draft shield door
will re-open.
For more information on turning this function on or off b y menu code, refer to
"Part III: Balance Operating Menu."

Weighing Range Structure

SuperRange - "SingleWide-Range Balance"
(identified by S in the model designation RC...S)

SuperRange models have an extraordinarily high resolution, i.e., the weighing
range has a resolution ranging u p to a few million digits. There is one level of
fine readability for the entire weighing range [for example: 0.01 mg).

DualRange
(identified by D in the model designation RC...D)

2 weighing ranges;
a fine range and a Standard range

The balance automatically)' switches from the fine range which is 10 times more
accurate (for example:
52 g capacity - readability of 0.01 mg) to the Standard range (for Instance:
210 g capacity -01 mg readability} when the balance is loaded beyond the fine
range limit (>52 g). The weight readout is displayed with the readabil ity o f the
Standard range until you tare in the fine range (loa d <52 g).

PolyRange
(identified by P in the model designation RC...P).

-Wide weighing range with multiple levels of accuracy

In the PolyRange balance, the weighing range is divided into as many as 3
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 press the tare control (24), you will obtain the highest possible resolu­tion, even when the balance is loaded.

18

Weighing in the IQ-Mode™

(Load-Dependent Readability)

In the IQ-Mode™ (IQ = Intelligently quick), weighing is done with a load­dependent readability of 0.01 % (for different settings, see "Part III: Bal a nce Op­erating Menu') throughout the entire weighing range of the balance. The display
resolution of the l a st digit changes in increments of 1, 2, 5, 10, 20, etc. in propor­tion 1o the weight of a sample.

Oftentimes, a display accuracy of 10 milligrams is sufficient for a load of approx.
110 g. In this case. it makes s ense to select weighing range R 1 with an accuracy
of 0.01 o/a by pressing the toggle key

(25).
While you are filling u p to a target weight. it is certainly easier to work with a
target of 110.20 g than with an absolutely accurate readout of 110.1S885 g.

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 a semi-microbalance, it gives
you the full accuracy of all 5 decimal places for initial sample weights below 1 g;
whereas for heavier samples (of 100 g o r more), it provides lower readability
which is sufficient:

Initial sample weight readout
Below 1 g

Above 100 g

0,98756 g
123,13 g

19

Mass Unit Conversion by Toggling

You can have the weight displayed in grams or milligrams.

To select the three weighing ranges one after the other, press the

toggle key

(25] each time.

In addition to grams and milligrams, this balance gives you a wide variety of
other menu-definable international weight unit options. For more information, re­fer to "Part III: Balance Operating Menu."

20

Calibration and Linearization

During calibration, the balance is adapted to changes in ambient conditions.

You should recalibrate your balance each lime you set it up in a different area or
when the ambient conditions change (fore example, temperature or barometric
pressure). When 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.

Make sure that the draft shield is closed before calibration or linearization Starts.

You can abort any calibration or linearization procedure by pressing the

key (28),

The balance offers you various calibration and linearization functions. The func­tion you select is indicated in the display by one of the following special codes;

»CALI« The balance has built-in calibration weights and can be calibrated

with the

key (“Quick-CAL" - see page 22)

»CALI« The calibration or linearization function is activated

»C.I.« Internal calibration

»C.t.« Calibration test

»L.I.« Linearisieren intern

»C.E.« Eternal calibration

21

Fully Automatic Calibration

lf the

symbol flashes, this means that the balance wants to self--calibrate. You
do not need 1o interrupt your weighing procedure, because the balance will wait
until it detects that you have stopped weighing for one complete minute.
Afterwards, the balance will perform fully automatic internal calibration.

During this procedure, the draft shield should be closed 1o ensure that calibration
is done correctly.

The symbol will flash until the balance Starts this fully automatic procedure on its
own o r until you activate one of the calibration functions by pressing a key (sees
next page).

The balance can perform fully automatic internal calibration two hour after it has
been connected to line power or once the temperature has changed by ±1.5 de­grees since the last calibration process. Independently of these factors, the bal­ance can perform a fully automatic calibration after four hours at the latest.

To turn off the fully automatic calibration function by menu code, refer to "Part III:
Balance Operating Menu."

In the fully automatic mode, the draft shield closes after

or the tare control is

pressed.

24

CALIBRATION TEST

Rather substantial changes In barometric pressure and temperature may affect t
he display response of these highly accurate Research Series balances.
To ensure that you obtain the full accuracy of these balances, even when you use
the entire weighing range, we have implemented a calibra tion lest function. It will
help you decide whether o r not you need to recalibrate your balance (for exam­ple, to maintain the same accuracy during long-term weighing series).

Press the tare control (24) for at least 2 seconds until "C.l." and "CAL" are dis­played (next to the

key).

Select the calibration test by pressing the

key (21) twice until "C.t." is dis-

played.

Interfacing Devices with the Balance

Please note that the interface port is electrically connected lo 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 co nnection may result in interference
caused by ground loops o r by transient currents if you have grounded the hous ­ing or connected the protective grounding conductor for line power. If necessary
connect an equipotent bonding conductor to the balance

28

Below-Balance Weighing

A port for a below-balance weighing hanger is available on the bottom of the
balance.

To fasten the hanger, open the below-balan c e por t by r emov i ng t h e tw o scr ews on
the bottom of the balance and detaching the closing plate.

Now you can attach a sample using a Suspension wire, for example.
Common applications for below-balance weighing include specific gravity deter­mination or immersing a sample in a special atmosphere (medium for reaction).
You can also use the M2 thread to attach a sample.

Important Note

When you use such below-balance weighing hangers, you must install a shield to
eliminate drafts..

How to Fasten the Antitheft Locking Device

To fasten the antitheft locking device, use the lug (16) located on the rear panel of
the balance.

At the place of installation, secure your balance with the lock.

Care and Maintenance

Before cleaning the balance, unplug the power supply from the wall outlet.

Cleaning the Balance Housing and the Draft Shield

Please do not use any aggressive cleaning agents (solvents or similar agents]. In­stead, use a piece of lint-free cloth which has been wet with a mild detergent.
Clean the semi cylindrical elements of the draft shield with a commercially avail­able glass cleaning agent.
Make sure that no liquid enters the balance housing.
After cleaning, wipe down the balance with a soft, dry piece of cloth.

Cleaning the Weighing Chamber

Keep the draft shield base plate from becoming too dirty:
Carefully remove spilled powder from the weighing chamber by using a small
vacuum cleaner (such as a small car vacuum cleaner with a mini-hose attached).
Afterwards, remove the weighing pan (7] and the shield disk (8) from the weigh­ing chamber.
Vacuum out the remaining powder from the weighing chamber using the same
equipment described above.
Do not clean the weighing chamber by blowing off powder from the parts!

To remove liquid spills, use blotting paper.

31

Safety Inspection

lf there is any indication that safe Operation of the balance is no longer war­ranted. turn off the power and unplug the balance from the power supply imme­diately. Lock the balance and the power supply in a secure place lo ensure that
they cannot be used for the time being.

Safe Operation of the equipment is no longer ensured when

—

there is visible damage 1o the power supply

—

the power supply no Ionger functions properly

—

the power supply has been stored for relatively Ion g periods under unfa­vourable conditions

In this case, notify your nearest Sartorius Service Center or the International Ser­vice Support Department based in Goettingen, Germany. Only service technicians
who have access to the required maintenance manuals are allowed to perform
maintenance and repair work 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 l oad

—

Equivalent leakage current <0.05 mA measured by a property 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.

How to Access the Menu

The Sartorius MC1 Balance can do much more than "just weigh."

It can "think" in various units of measure, adapt to unfavourable 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 special requirements.

For your convenience, the m enu codes have been factory-set so that you do not have to make any changes if yo u want to "just
weigh," and if your balance will be operated under normal ambient conditions.

To select specific functions, you will need to set the respective menu code.
This code tells the microcomputer inside the balance what it has to do to meet your requirements.

Here is a short example to help you understand how to set a menu code.

Just take a look at the picture below.

See the apple on one of the trees?
Now if you want to explain to somebody where this apple is located, you could number the trees, the main branches and the
small branches according to a certain pattern.
Then you could describe the location like this: the apple is on tree no. 3, main branch no. 1 and small branch no. 4. To express
this as a menu code, you'd say: 3 1 4.

Now that’s easy enough, isn't it?

4

The areas where certain code settings are found in the balance/scale operating menu are designated similarly to the way in
which the location of the apple is pinpointed.

Going back to our example, tree no. 3:
The apple is located exactly where the unit symbol "ct" is on our menu "tree."
On main branch no. 1, you'll f ind all weight units for the seco nd weighing range which you select with the toggle key

. On
small branch no..4, carats - "ct" is defined
as the weight unit - so your code will be 3 1 4.

The weight unit "g" for grams is on the same tree (3) and the same main branch (1 ), but on small branch no. 2.
Therefore, the code for grams is 3 1 2.
The code for pounds (lb) is 3 1 5, and so on.
(For a list of codes, see "Overview of the Weight Units," column for the "2nd range," on page 14.)

At this point, you'll probably want to know how to change the menu codes stored in your balance.

Go right ahead and try to change a few of the menu code settings. That’s the best way to familiarize yourself with the
performance capabilities and the versatility of the microcomputer in your Sartorius Balance.

Don't worry!

Even if you've selected the "wildest" codes and totally thrown off all the code settings you need, all you have to do is press a
key to set things straight again.
Your balance will work just like it did when it left the factory - with the original factory-set menu codes.

There are three Steps to changing a code:

- access the menu

- set a code

- confirm and store this code

To set a code, use the four keys which are defined on the display as arrow points to indicate the direction.

Function Key

Go back

Go forward

increase

Decrease

5

Now for a little hands-on practice!

It's your turn to try a setting - how abo ut cha ng ing the weight unit in the second weighing ra nge (use

to select this range)

from grams to carats (et), Code: 3 1 4. (In our example, the 1

st

weighing range " " will remain unchanged.)

The balance operating menu is protected against accidental changes. That’s why you'll need to "unlock" it:

Change from the Status readout

to

-L- Stands for "list" for checking menu code settings, and

-C- Stands for "change" for selecting a different menu code.

In the following directions, we've included diagrams to show you what you actually see on the display and which key you need
to press, for example:

The text next to the diagrams tells you how to carry out each Step

6

Examples for Changing Menu Code Settings

How to set code 3 1 4 for "ct" in the second weighing range

- Turn off the balance

- Turn it back on

- While all segments are displayed, briefly press the tare control

- If -L- is displayed, unlock the menu access switch

- Remove the protective cap located to the left of the AC jack o n the re ar pane l

of the balance, and move the switch in the direction of the arrow

- Change the left-hand number to “3”

- Move to the middle number

- Now move from "1" to the right-hand number (Whe n yo u m o ve to the right-

hand number, the previously set numeric code will appear.)

- Change the right-hand numbe r to “4”

- Confirm the code setting

Important Note:
You must press the tare control

in order to .confirm the code you have just set:

This is indicated by the "o" after the code.

- Press

to store your menu code setting

7

That’s all there is to it!

Now, if you press the

key, you can read the weight in carats "ct":

Of course, you'll be in the IQ-Mode™, with a load-dependent readability of

0.01%, as defined by the factory-set menu code.

You say you don't like it?

You'd rather weigh in the unit "ct" with the highest possible accuracy down to the
last digit?

No problem!

Just set the appropriate code:
3 2 1. (You'll find this code listed under "Display Modes" on page 16.)

How to set code 3 2 1 for full resolution in the second weighing range

- Turn off the balance

- Turn it back on

- While all segments are displayed, briefly press the tare control

- Change the left-hand number to “3”

- Move to the middle number

- Change the middle number to “2”

- Move from "2" to the rig ht-ha nd number (When you move to the rig ht-ha nd

number, the previously set numeric code will appear.)

- Change the right-hand numbe r to “1”

8

- Confirm the code setting

Important Note:
You must press the tare control

in order to .confirm the code you have just set:

This is indicated by the "o" after the code.

- Press

to store your menu code setting

Now you can read the weight in "ct" accurately down to the last digit.

Congratulations! You've just finished the two examples we've given to help famil­iarize you with how to use the code setting function.

Remember, the keys labelled

, , , , and have special functions

in this mode:

and = Move to the le ft and right, re spe ctive ly

and = Respectively increase and decrease a number by one

= Confirms a code setting

= Stores a code setting and leaves the menu

n the application programs, the

and keys will have other f unctio ns deter-

mined by the program that you have selected.

The particular function assigned is always shown on the display next to each key
for easy identification.

Before you begin to look for different menu codes in the description of the appli­cation programs, you should try out the reset function to undo all changes in order
to see how it works.

How to Undo 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
so that your balance will operate according
to them. To use this function, you will need to select code 9 - - 1.

How to set code: 9 – – 1

- Turn off the balance

- Turn it back on

- While all segments are displayed, briefly press the tare control (

)

- Change the left-hand number to “9”

- Move to the middle number

For this code, the middle number is skipped.
Instead, you will always obtain the right-hand number.

- Change the number to “1”

- Confirm the code setting

Important Note:
You must press the tare control (

)to confirm the code you have just set:

This is indicated by the "o" after the code.

- Press “

” to store your menu code setting

All menu code settings are now the ones which were originally set at the factory.

10

Note:
The actual 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 select the left and the middle numbers,
which means the entire menu code setting is displayed. This makes it easy for you to check the m e nu code se ttings.

Please do not forget to relock the balance operating menu. The "-L-" indicates that it is currently locked:

You can lock the menu anytime you wish once you have accessed it. However, it is best if you wait until you have changed the
last code setting.
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 l ock.
In this case, "-C-" will be displayed whenever you access the menu:

The lists on the next pages give just a small sampling of the code options available for the balance operating menu. These
options involve Standard balance Operation, utilities for printouts or data transfer, and additional functions.

lf you would like to change several menu code settings, you do not have to press

/ after each change to leave the balance

operating menu.

For your convenience, we've indicated all factory code settings with an "*."

You'll find information on the application programs in "Part IV."

A quick-reference guide listing all menu code options for the "Standard" operating parameters of the balance is given in the
section starting on page 34. This guide also provides space for you to enter any changes to the menu codes.

Balance Operating Parameters

How to Adapt the Balance to Ambient Conditions

To adapt your balance to ambient conditions, you may need to change the response time (see the Product Data Sheet).

Code
Very stable conditions 1 1 1
Stable conditions * 1 1 2
Unstable conditions 1 1 3
Very unstable conditions 1 1 4

Standard Weighing Mode - Manual Filling Mode

You can optimally adapt your balance to meet either of these requirements.
In the manual filling mode, the display compensates for fluctuations of the load on the balance so that you obtain a steadier
readout.

Code
Standard weighing mode * 1 2 1
Manual filling mode 1 2 2

Stability Range

The stability range in digits works together with the stability symbol (unit symbol).
When the stability symbol is displayed, the weight readout is stable within the defined range.

Readout is stable within ± Code
0,25 digit ** 1 3 1
0,5 digit 1 3 2
1 digit 1 3 3
2 digits * 1 3 4
4 digits 1 3 5
8 digits 1 3 6

* = Factory setting
** = Setting not available for balances with 0.01 mg readability

12

Stability Symbol Del a y

This setting allows your balance to compensate for individual interfering factors which slowly subside, such as turbulent air
currents generated within the weighing chamber.

Code
No delay 1 4 1
Short delay * 1 4 2
long delay 1 4 3
Extremely long delay 1 4 4

Tare Parameter

You can define when the balance will perform the taring Operation:

Code
At any time 1 5 1
not until the readout is stable * 1 5 2

Auto Zero Function

When this zero tracking function is activated, any changes off of the zero readout that are equal to a defined fraction of digits
per second are automatically tared. In other words, it ensures a stable zero.

Code
Auto Zero on * 1 6 1
Auto Zero off 1 6 2

* = Factory setting

13

Weighing in Three Ranges

The toggle key

lets you switch back and forth among three weighing ranges.

lf the menu code is set for three ranges, press the

key each time to toggle to a different range.

How to Select the Number of Ranges

Code
Block the key 2 1 1
Two weighing ranges 2 1 2
Three weighing ranges * 2 1 3

lf two or three weighing ranges are defined by menu code, the ID displayed for the particu lar r ange ju st selected will ch an ge as
follows:

ID displayed

1

st

range 2nd range 3rd range
Two weighing ranges R1 R2
Three weighing ranges – – – **) R1 R2

Weight Units

The "initial weight unit" is the unit in which your balance will weigh the moment you turn it on. This unit is defined in the 1

st

range.
You can select a different unit for each weighing range by setting the appropriate menu codes.

Important Note:

You can select almost any weight unit; however, this may entail a loss of resolution, since the number of places which can be
displayed is limited (e.g., if you select "kilograms.")

* = Factory setting
**) The weighing range available when the balance is on is identified only by the scale symbol.

Codes 1 7 1, 3 1 1 and 3 3 1 are reserved for programming special units to meet the needs of customized applications. The
Standard, factory-set unit is grams.
In the display, you will see "o" as the stability symbol for a stable readout, just as for kilograms.

Some unit Symbols printed on hardcopy or output on a Computer screen will differ from the way they are shown on the
balance display:
This applies to code numbers ending with 3 = kg
6 = tlh
9 = tls
10 = tlt

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 weight digit changes in increments of 1, 2, 5, 10, 20, etc., in
proportion to the weight of the sample.

Oftentimes, a display accuracy of 10 milligrams is sufficient for a relatively heavy load.
In this case, it makes sense to select the 2nd weighing range (identified as "R 1" for 3 ranges) with an accuracy of 0.01 % - a

touch of the toggle key

is all it takes. In the second weighing range (codes 3 2 1 through 3 2 13), a load-dependent
readability of 0.01% has been factory-set.
While you're filling up to a target weight, it is certa i nly easier to work with a target of 110.20 g than with an abs olutely
accurate readout of 110.19885 g.

By selecting this function 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 level of accuracy. The IQ-Mode™ meets this
requirement - on a semi-microbalance, it gives you all 5 decimal places for initial sample weights below 1 g; whereas for
heavier samples of 100 g or more, it provides pro p ortionally lower readability which is usually sufficient:

Initial sample weight Readout (for a code setting of 0.01 %)
Below 1 g Æ 0.98756 g
Above 100 g Æ 123.13 g

This mode for adapting the display accuracy enables you to weigh with constant proportional precision between 1 % and

0.01% over the entire weighing range of your balance. The particular accuracy you choose is indicated in the top right corner
of the application display field.
Select the load-dependent display accuracy independently for each of the three weighing rang es.

lf you are only interested in the final readout, you can select this mode by setting code 2 5 1. A special symbol "- -" will be
displayed in any weighing range until the final stable readout appears in digits. For the Standard readout mode, set code
2 5 2 (all readouts in digits).

Readout mode Code
Special symbol “ – – “ for unstable readings when load changes 2 5 1

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.
In the process, the last numeral is blanked until the load stabilizes. Once the load stabilizes, the readout is shown again with
the full display accuracy, which means the
last numeral is displayed.

Display Accuracy t

You can define the level of accuracy by changing the displ a y increments, also called "scale intervals" (of the l a st numeral). The
display increments p ossible 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 with reduced display accuracy.
To make this concept easier to understand, the three levels are designated as "rounding factors" in the tables summarizing the
various menu code settings.

PolyRange Function (application for "single-range" balances)

The PolyRange function divides a single weighing range into as many as 3 ranges, each with a different readability. In the
various ranges, the readability will adjust so that the last numeral of a readout Ts displayed with a resolution of 2 or 5
increments. 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 control at any range level to restore the full
resolution of the first range, even when the balance is loaded.

which are activated by holding down the tare control

for a few seconds:

– External calibration C.E.
– Internal calibration C.I.
– Calibration fest C.t.
– Internal linearization L.I.
– External linearization L.E.

However, if the menu access switch is unlocked ("acce ssibl e " Status indicated by -c- after you have accessed the balance
operating menu), the "external calibration" function will be accessible even though you have set the menu code 1 9 2 for
"access denied."

Multiple Calibration Mode

The calibration accuracy can be increased. The calibration values calculated from the average of the individual calibration
procedures. You can use the "multiple calibration mode" for both infernal and external calibration. The number of calibration
procedures is indicated in the 3rd place of the application display field (e.g., "C 1 5”).

Important Note:
lf "Err 04" is briefly displayed, the calibration va lues deviate too much from one another. This means the calibration value
measured is not stored, and the calibration procedure will be repeated.

Utilities for Printouts or Data Transfer

Sartorius MC1 Balances come Standard with an interface.

You can plug a Sartorius Printer or a Computer into this interface port to print data on hard copy or transfer them to your
Computer. Moreover, you can choose to Output data from your balance to this on-line device either automatically or by
pressing the print key on the balance.

The balance operating menu lets you define the various parameters for data output.
For information on the data formats and for interfacing a Computer or a different peripheral device, see "Part V: Interface
Description."

Data Output Parameter

This parameter is coupled with or without the stability parameter = stable readout or no motion is detected
Print on request = data is output only when the print key is pressed or a Software command is received
Auto print = continuities. automatic data output

Code
Print on request regardless of stability 6 1 1
Print on request after stability with storage of the function * 6 1 2
Print on request after stability without storage of the function 6 1 3
Auto print regardless of stability 6 1 4
Auto print at stability 6 1 5

Automatic Data Output

You can stop and Start automatic data output by pressing the print key. To avoid operating errors or to ensure that data will be
output continuously in the automatic mode, you can block this function

Code
Start/stop auto print using the print key 6 2 1
Auto print not stoppable * 6 2 2

* = Factory setting

21

Data Output at Defined Intervals

You can reduce the volume of data in the "auto print" mode by defining the interval at which data will be Output automatically .
This auto print interval is based on the number of times the display is updated.

Auto print interval Code
1 display update * 6 3 1
2 display updates 6 3 2
5 display updates 6 3 3
10 display updates 6 3 4
20 display updates 6 3 5
50 display updates 6 3 6
100 display updates 6 3 7

Automatic Taring after Data Output

This convenient setting lets you checkweigh a series of samples or products without having to unload the balance after each
weighing Operation.
This means less work for you:

– the sample remains on the pan after the weight readout has been printed or transferred to an on-line Computer
– the balance is tared automatically after the weight readout has been printed or transferred to an on-line Computer
– you simply load the next sample or part

Automatic taring after data output Code
Data output without automatic taring * 6 4 1
Data output with automatic taring 6 4 2

Data ID Codes

To help you identify weights, piece counts, percentages, etc., a code letter is printed or displayed in front of these values.
For example, an "N" printed or displayed before a weight value identifies it as a net weight. You will find the data ID codes of
a particular application program listed in the corresponding description. This ID code increases the data Output format from
16 to 22 characters for each weight readout.

Additional Functions

A number of additional menu codes enable you to assign or deny access to various functions.

Menu Access Function

You can define the function of the menu access switch by setting the code for the balance operating menu to "accessible." In
this setting, "-C-" will be displayed on your balance whenever you access the menu.
This means that you can change the menu codes at any time regardless of the setting the menu access switch.

Access to the balance operating menu Code

23

Analog Display: Bar Graph/Marker

In the factory setting, the analog display works as a bar graph: By changing the menu code, you can turn the analog display
completely off or have it appear as a marker.
When the marker is selected, two individual Segments will move within the display scale range to indicate the loading Status of
your balance.

Analog display Code
Off 8 5 1
Bar graph * 8 5 2
Marker 8 5 3

Power-On Mode

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 Æ on ÅÆ 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; after the
balance has been disconnected from line current; or after the

key has been pressed. In this setting, the balance can no

longer be turned off by the

key.

Power-on mode Code
(power) off Æ on Æ standby * 8 6 1

24

Fully Automatic Draft Shield Function

You can define the fully automatic draft shield function to meet the most diverse requirements in o rder to sho rten work
procedures and make them easier. After you have pressed a function key (or after a control command has been received – see
"Part V: Interface Description"), the draft shield will dose automatically and the balance will then perform th e par ticu lar function
activated by the key. lf code 8 11 2 or 8 11 3 is set, the draft shield will open once the function selected has been performed.

In code setting 8 11 4 or 8 11 5, the last numeral is displayed when a balance with 0.01 mg readability is turned on.

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 11 1). Otherwise, if a power outage occurs and the balance is automatically restarted (e.g., code 8 6 3 or 8 6

4), the robot arm may accidentally hit the draft shield as it is closing.

The draft shield operates automatically for the following functions:

— powering on the balance (

key)

— taring once the balance has stabilized (tare control

)

— printing on request after stability (

key)

— starting the calibration function (

key)

— using the tare memory once the balance has stabilized (

key) - see also "Part IV: Application Programs"

— storing weights during over/under checkweighing (

key) - see also "Part IV: Application Programs"

— storing weights while weighing in percent and counting (

key) - see also "Part IV: Application Programs"

Automatic draft shield function Code
Off 8 11 1
Close draft shield – perform function after stability – open draft shield 8 11 2
Close draft shield – perform function with stability symbol delay – open draft shield 8 11 3
Close draft shield – perform function after stability * 8 11 4
Close draft shield – perform function with stability symbol delay 8 11 5

Important Note

For calibration, make sure to press the

key to dose the draft shield.

* = Factory setting

25

Display Accuracy with the Draft Shield Automatically Opened or Manually Adjusted

You can define the display accuracy for the automatically opened or manually adjusted draft shield by changing the
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 six levels so that you
will obtain a faster readout with reduced display accuracy (convenience feature for weighing-in). To make this concept easier
to understand, the six levels are designated as "rounding factors" in the tables

Code
Highest possible accuracy * 8 12 1
Rounding factor 2 8 12 2
Rounding factor 5 8 12 3
Rounding factor 10 8 12 4
Rounding factor 20 8 12 5
Rounding factor 50 8 12 6
Rounding factor 100 8 12 7

IQ-Mode™ with the Draft Shield Automatically Opened or Manually Adjusted
(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 weight digit changes in increments of 1, 2, 5, 10, 20, 50, etc.,
in proportion to the weight of a sample.

While you're filling up to a target weight with the draft shield open, it is certainly easier to work with a target of 110.20 g than
with an absolutely a ccura te readout of 110.19885 g.

By selecting this function for automatic adaption of the display accuracy, you will obtain stable weight readouts even faster.

The IQ-Mode™ enables you to weigh with constant propo rtio nal pre cisio n be twe en 1 % and 0.01 % throughout the entire
weighing range of your ba lance.

GLP/GMP Print or Record

The Research Series Balance can record all completed calibration operations and print out data in compliance with the
requirements of Good Laboratory Practice (GLP).
The balance, interfaced with a Data Printer or a Computer, creates a document that records the date, time, serial number and
model number which makes it possible to clearly trace data to the balance that generated it and the time at which it was
generated.

Application:
Use of the balance in quality assurance Systems in areas subject to compliance with GLP/GMP.

Select the GLP/GMP printout/record mode by setting the appropriate code in the menu of the balance operating program.

In addition to the functions implemented strictly for weighing, Sartorius Balances of the MC1 generation offer you a variety of
application programs to handle tough daily routine work in the laboratory as well as in industrial plants.

lf you have not yet experienced how fast and accurately a Sartorius Balance can count parts or convert weights into
percentages, now is a good opportunity to try it out.

In this description, you'll find a few simple examples for the following applications:

Tare Memory

Weighing in percent

Over/under checkweighing

Counting

You can also use these programs in combination.
How?
You'll discover the ins and outs in the examples described on the next pages.

To select an application program or a specific function, set the appropriate co de in the menu. Part III describes in detail how to
set menu codes.
For quick information on setting these code s, se e page xyz in this manual for brief instructions.

Additional settings for running the particular program and displaying or printing the data on hard copy are listed in a fable of
codes.

One thing you should do when you want to set the code for a different program, or when someone else has already operated
the balance is:
Select the reset function - code 9--1 ° - to change all me nu code s back to the o riginal factory settings.

Over/Under Checkweighing

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 24. The factory setting is for to lerance 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

These programs enable you to checkweigh in any range that can be selected with the toggle key labeled

.

Instead of weights, you can use percentages or piece counts for checkweighing if you have selected the corresponding
application program by menu code. You will find examples of these in the section dealing with checking net weights.
Both programs provide four control lines via the balance interface, which are called data output port lines. This means you can
interface a remote display unit that has colour-coded indicators, which are activated by the lines depending on the target
weight and the tolerance limits selected.

For more informatio n, see the "Interface Descript ion" in Part V.

You can use the Sartorius Three-Segment Checkweighing Display Unit, model
YRD10Z, as a visual aid during checkweighing.

Checking Net Weights-Weight Readout Code 2 2 3

To store a weight readout as the target weight, press

.

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.
lf the weight of a product is "okay," the last segment of the bar graph will be within the tolerance range of the checkweighing
indication. You can also read the actual weight in digits.

Counting

A weight readout is stored as a reference sample quantity (factory setting: 10 pcs). To change this value, see the description on
page 30.
(The reference sample quantity is displayed as long as the reference sample weight has not yet been stored for counting.) While

counting (piece count readout), you can press

identified by - OPT - to Update the reference sample for optimising the
accuracy (approx. double the reference sample quantity). In the process, the reference weight is recalculated based on the total
reference sample weight and the piece count displayed.

Breaking Bulk/Portioning Code 2 1 4

A weight readout is Stored as the reference sample quantity (factory setting: 10 pcs), although it is shown with a negative sign.
To change this value, see the description on page 21.

While counting (piece count readout), you can Update the reference sample by pressing

identified by - OPT - (approx.
double the reference sample quantity) if the average reference piece weight is too light. In the process, the reference weight is
recalculated based on the total reference sample weight and the piece count displayed.

Reference Sample Updating

While counting (piece count readout), you can press

identified by - OPT- to Update the reference sample for optimizing the
accuracy. In the process, the reference weight is recalculated based on the total reference sample weight and the piece count
displayed.
It makes sense to use the reference sample updating function when the weight of a refer en ce sample qu an tity is lighter th an 1 0 0
digits. In this case, you should approximately double the reference sample quantity. You can repeat reference sample updating
several times, using double the quantity for each updating Operation.

Use in Combination with Other Programs

The counting program can be used in combination with other application programs.
This means you have all functions of the combined program additionally available.
