new balance.
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 31inches).
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 ekey (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:
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.
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.

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.

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

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.

Voltage Selection
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 mm2and for .18” standard gauge or 4 mm2
stranded wires.
