Installation Instructions

Ambient Conditions

Microbalances are highly precise and very sensitive measuring
Instruments. Therefore, please choose a suitable place to set
up your balance. lt should not be exposed to the following:

- Heat radiation

- Aggressive/corrosive substances

- Vibrations

- Drafts

Use a balance table or a wall console (see "Accessories") to set
up your balance.

lf you wish to move your balance to another location,
please follow the directions on page 23 under "Transport­ing the Balance."

Do not expose the balance to extreme moisture over long peri­ods. Moisture in the air can condense on the surfaces of the
balance whenever a cold balance is brought to a substantially
warmer place.
lf you need to transfer the balance to a warmer area, make sure
to condition it for a few hours at room temperature. The best
way to prevent moisture condensation is to leave the balance
connected to line power. The components used in the balance
are rated to at least class KSF according to DIN 40040.

Your Sartorius Balance will provide accurate readouts even
when it is exposed to unfavorable ambient conditions.
You can adapt the balance to your requirements simply by
changing the menu code settings in the balance operating pro­gram.
For this purpose, read pages 19 through 21

Connecting Electronic Devices (Peripherals)

Turn off the balance by pressing the ON/OFF key (8)
(STANDBY state), and wait until the weighing system of the
balance has been arrested automatically for transportation (see
also "Transporting the Balance" on page 23). Unplug the power
supply before you connect or disconnect devices to or from the
interface ports.

To reduce distortion of the weight readouts caused by ambient
conditions (turbulence within the weighing chamber, for exam­ple), balance-generated data should be allowed to stabilize for
about 10 seconds before they are transmitted to an online
printer or other peripheral device.

9

Startup

Preparing the M3P for Operation

Connecting the Balance to Line Power

The balance is energized by a portable power supply. Make
sure that the voltage rating printed on this unit is identical to
your local line voltage rating.

lf the voltage rating specified on the power supply or the plug
design does not match the rating or Standard you use, please
contact your Sartorius dealer.

Important Note

Only use original Sartorius power supplies identified by the Sar­torius label. Use of power supplies made by other manufactur­ers, even if these power supplies have a registered approval
rating from a national testing laboratory, requires the consent of
a certified Sartorius technician.

Plug the cord of the power supply into the power receptacle of
the balance. Secure the connection by tightening the knurled
collar.

Now plug the power supply into a wall outlet.

11

Voltage Selection

You can select the voltage only if you use our portable power
supply (69 70903) that has a European-type plug (rounded
prongs).

Safety Precautions

The power supply rated to Class 2 (double insulated) can be
plugged into a wall outlet without taking any additional safety
precautions. The pole of each Output voltage is connected to
the balance housing, which can be grounded for Operation.

The interface (see "Interfacing Devices" on page 26 in addition)
is also electrically connected to the balance housing (ground).

Leveling the Balance using the Level Indicator

At the point of use, level the balance using the leveling feet (7)
so that the air bubble is centered within the circle of the level in­dicator (6).

12

How to Operate the Balance

General Directions for Working with the Balance

Before you start weighing, please observe the
following:

After plugging your balance into a wall outlet
using the power supply, make sure to allow for at
least 2 hours' warmup.

Working with a microbalance requires a steady hand and a
smooth, uninterrupted technique.

Use forceps or other suitable Utensils to place your sample on
the pan.

Do a few trial weighing procedures before you begin with actual
weighing of your sample, because a weighing chamber that has
not been opened for a relatively long period may have a tem­perature different from that of the balance's surrounding envi­ronment. Therefore, as soon as you open the weighing cham­ber, a change in temperature will inevitably occur. This change
in temperature may show up as a change in the weight readout.
In this case, we recommend that before you begin with an ac­tual repetitive weighing procedure you open and dose the
weighing chamber at the same rate as you will be doing during
such a procedure.

Carefully place your sample on the pan and, if necessary, re­move it along with the pan. After the weighing chamber is
closed, the weight readout will stabilize after about 15 to 30
seconds as a rule. The accuracy of the weight readouts will in­crease as you perform successive weighing procedures with
greater consistency.

13

Weight Display

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

BUSY

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

STANDBY

The display has been turned off with the ON/OFF key (8) and
the balance is now in the ready-to-operate mode so that it does
not require warmup.

POWER OFF

The balance was disconnected from line power (reconnection to
line power after the balance was unplugged; power failure or
outage).

CAL

The calibration function has been activated.

Turning the Display On and Off

Press the ON/OFF key (8) to turn the display on or off.
You can also turn it on by pressing the tare control (12).
After the balance has been connected to the power supply, the
display will go out when ever you turn off the balance using the

ON/OFF key. The LEDs next to the symbols "

~ 750 mg" and

"

~ 1500 mg" below the weight display indicate that the bal­ance has already arrested the weighing system automatically
(see page 23 "Transporting the Balance" in addition). All other
electronic circuits will remain energized (indicated by
STANDBY). This means the balance is immediately ready to
operate without requiring warmup the next time you turn it on.

14

Self-Test

After the balance is tumed on, an automatic self-test of the
balance's electronic circuitry is performed.
This self-test ends with the readout "CH2" and will change to "L"
after about 10 seconds.

When the LED lights up next to the syrnbol "

~ 1500 mg"
below the weight display, this indicates that the balance's
weighing System has not yet been arrested.

Weighing

Press the key labeled

(10) whenever you want to Start

weighing.

The readout 0.000 mg will now be displayed.
Both LEDs next to the symbols "

~ 750 mg" and " ~ 1500

mg" will go out.

At this point, place your sample on the pan to determine the
weight and dose the weighing chamber. Do not read off the
weight in the display (14) until the small circle (above the "mg"
symbol) appears as the stability symbol. The weight readout
is stable a few seconds afterwards, as a rule.

Weighing Filters on the M3P-000V001

The M3P-000V001 filter microbalance comes with Standard fil­ter weighing pans with an effective diameter of 73 and 105 mm
(2.9" and 4.1"), respectively, which can be used as loading
space.

Weigh filters up to 70 mm (2.8") diameters on the small pan and
filters with diameters between 70 and 100 mm (2.9" and 3.9")
on the large pan (see also "Preparing the Filter Microbalance for
Operation").

15

Taring

If you wish to use a Container or if the weight display does not
indicate 0.000 mg, press the tare control to zero the display.

Weighing with a Tare Container*

The balance has built-in motorized Substitution weights (tare
weights) for application of about 750 mg or 1,500 mg (accuracy
approx. 1 mg) to expand the weighing range.

lf the weight display indicates an "H," the tare Container ex­ceeds the capacity of the 1,500 mg electronic weighing range.

Press the key labeled

(10).

The LED next to the symbol "

~ 750 mg" indicates that the
750 mg Substitution weight has been applied by motor. Now a
weighing range of 750 mg to 2,250 mg is available.

For even heavier tare Containers (overload symbol "H" in the
weight display) you can press the

key again to expand the

range.
The LED next to the symbol "

~ 1500 mg" indicates that 1,500
mg are applied by motor.
Now a weighing range of 1,500 mg to 3,000 mg is available.

Zero the display when the small circle appears above "mg"
in the weight display. Now you can weigh your sample in
the tare Container.

16

Important Note

The electronic weighing range is 1,500 mg.

Press the key labeled

again to return to the normal weigh-

ing range from the one expanded by tare weight compensation.
Both LEDs next to the symbols "

~ 750 mg" and " ~ 1500

mg" will then go out.

Below-Balance Weighing

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

Open the below-balance port by turning the closing plate. Then
attach the hanger for below-balance weighing to the hook.

Important Note

For below-balance weighing, make sure to install a special draft
shield to ensure correct readouts.

Auto Zero

This balance has an automatic zero tracking function known as
"Auto Zero" (can be turned off by menu code - see "Balance
Operating Program").
The Auto Zero function ensures that the unloaded balance will
continue to provide a zero readout (rules out most of the effects
of ambient conditions causing the readout to drift).

17

Calibration

Unload the pan and dose the weighing chamber. lf necessary,
re level the balance using the level indicator as a guide.

Internal Calibration:

The internal calibration weight conforms to accuracy class E

1

of

the International Organization of Legal Metrology (OIML).

Select the weighing range of 0 to 1500 mg (both LEDs next
to the Symbols "

~ 750 mg" and " ~ 1500 mg" go out).

Press the CAL key (13). "CAL" will now be displayed below the
weight readout.

Remove both Substitution weights. "L” is now displayed on the
balance. Afterwards, place the weights back on the pan. The
weight readout is displayed again.

Zero the display and press the CAL key (13) again when the
display shows a zero readout. The weight display now
indicates "C."

lf "CE" is displayed instead, zero the display and press the
CAL key again.

After a few seconds, "CC" will be displayed followed by 0.000
mg. An acoustic Signal indicates the end of the calibration pro­cedure.

Important Note!

While calibration is in progress, indicated by "C" or "CC" in the
display, do not press any key.
However, should you do so by mistake, just turn the balance off,
then on again with the ON/OFF key. Following this, repeat cali­bration.

18

External Calibration:

Unload the weighing pan. Select the 0 to 1500 mg weighing
range (both LEDs next to the Symbols "

~ 750 mg" and " ~
1500 mg" go out). As soon as you obtain a zero readout, press
the tare control (12) for at least 3 seconds until the calibration
weight readout appears in the weight display (14).

Center the calibration weight of the desired accuracy class on
the weighing pan and dose the weighing chamber.

A circle is now displayed above the "mg" symbol. An acoustic
signal indicates the end of the calibration procedure.

Open the weighing chamber and remove the calibration weight
from the weighing pan.

You can block access to both the infernal and external calibra­tion functions - to find these menu codes, refer to the "Balance
Operating Program."
These functions are accessible whenever the balance operating
program has been unlocked using the menu access switch (11).

19

Balance Operating Program

The balance operating program lets you adapt your balance to
various ambient conditions and application requirements.

At the factory, we have set the codes for a Standard program
which is protected by a locking function to prevent accidental
changes.

The "menu code" contains the information of the operating pro­gram, lt consists of three digits, known in "computerese" as the
page (1st digit), the line (2nd digit) and the word (3rd digit).

Reading a Program Menu Code (List Mode)

How to access the menu of the balance operating program:
With the display turned off (STANDBY state), hold down the
tare control (12) and briefly press the ON/OFF key (8). Once the
display indicates "CH2," release the tare control. The Status of
the balance operating program will be indicated in the weight
display at the end of the automatic self test:
"L” Stands for the list mode. In this mode, you can read a menu
code setting, but you cannot change it.

Changing a Program Menu Code (Change Mode)

lf you wish to change a program menu code, you must first
unlock the menu access switch to access the program menu.

To do so, remove the protective cap located on the front right of
your balance, and slide the menu access switch (11) in the di­rection of the arrow. The display will indicate "C," which Stands
for the change mode, meaning you can now change a menu
code setting.

20

After you have accessed the menu of the operating program,
the display will show a continuous sequence of numbers from 0­5 for the "page" or first digit of the code, in addition to the Status
code letter "L' or "C".
When the first digit of the code you wish to check or change ap­pears, press the fare control (12). The "page" code number (1st
digit) now stops in the display, and a series of numbers for the
2nd digit or "line" will begin to cycle. Press the tare control again
to stop the code number of your choice in the display. Next, the
numbers for the "word" (last digit) will cycle in the display. Re­peat the procedure to enter the last digit of the code.

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

To change any menu code settings ("C" mode), press the tare
control as soon as the appropriate numeric code is displayed.

Brief display of BUSY and the "o" symbol confirms your selec­tion, followed by a return to "zero" for the 2nd digit or "line."

How to return to the weighing mode:
Press the tare control each time a 0 appears in the numerical
sequence (word, line, page). lf you have changed a menu code,
it will be stored as soon as the display returns to the weighing
mode and 0.000 mg is indicated.
Lock the balance operating program using the menu access
switch and replace the protective cap.

Transporting the Balance

To transport the balance, the weighing system must be arrested
as described in the following.

Transport Arrestment

Before you unplug the balance from the power supply, turn
off the balance using the ON/OFF key (8). The LEDs next to
the symbols "

~ 750 mg" and " ~ 1500 mg" below the
weight display will now light up, indicating that the weigh­ing system of the balance is being arrested automatically
for transportation. As soon as the LED's go out, automatic
arrestment of the weighing system has been completed.

Remove the weighing pan (1) or the filter pan (19/20). Use your
fingers to carefully lift the interior draft shield (3) along with the
assembled pan support (2) or filter pan holder (17/18) out of the
weighing chamber. Disassemble the parts and replace then in
the case for the kit of accessories.
Place a rubber band over both knobs of the weighing chamber
doors to prevent then from sliding open when the balance is
transported.

The balance must be conditioned each time you move it to
another location.

24

Care and Maintenance

Cleaning

Please do not use any aggressive cleaning agents (solvents or
similar agents). Instead, use a piece of cloth wet with a mild de­tergent to clean the balance.
Make sure that no liquid enters the balance housing.
After cleaning, wipe down the balance with a soft, dry piece of
cloth.

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
immediately. Lock the equipment in a secure place to ensure
that it cannot be used for the time being.
In this case, notify the Sartorius Technical Services Dept. or Di­vision. Only certified Sartorius service technicians who have the
proper manuals are allowed to perform maintenance and repair
work on the balance.
Safe Operation of the balance with the power supply 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 relatively long periods
under unfavorable conditions

—

the power supply has been exposed to rough handling dur­ing shipment

We recommend that the balance with the power supply be in­spected according to the following checklist by a qualified Sarto­rius Service technician:

—

Leakage current <0.05 mA measured by a properly cali­brated multimeter

—

Insulation resistance >7 M

Ω

measured with a constant volt-

age of at least 500 V at a 500 k

Ω

load

The duration and number of measurements should be deter­mined by a qualified Sartorius service technician according to
the particular ambient and operational conditions. However,
such inspection must be done at least once a year.

Interface

See the "Interface Description for Sartorius Balances and
Scales" enclosed.

Interfacing Devices with the Balance
(RS Interface)

Make sure that the interface port is electrically connected to the
protective grounding conductor of the balance housing. The ca­bling supplied as accessory components is shielded and electri­cally connected on both ends to the cases of the connectors.
This electrical connection may result in interference caused by
cables scraping the floor or by transient currents if you have
grounded the housing or connected the protective grounding
conductor for line power. If necessary, connect an equipotential
bonding conductor to the balance.
