The PMA35001 scale is specially designed
for use in paint-mixing applications.
This scale can be operated through the
keypad in stand-alone operation or using
application software (such as a paint-
mixing program from a paint manufac-
turer) installed on a connected PC.
If you wish to create your own applica-
tion software, Sartorius can supply the
required drivers for DOS or Windows
operating systems.
Note:
– Make sure to read these operating
instructions carefully before installing
and operating your PMA35001 scale.
– As described in the manufacturer’s
declaration, type PMA35001 electronic
scales (only with the power cord supplied

Warnings and Safety Precautions
The weighing instrument complies with
the European Council Directives as well as
international regulations and standards for
electrical equipment, electromagnetic
compatibility, and the stipulated safety
requirements. Improper use or handling,
however, can result in damage and/or
injury. To prevent damage to the equip-
ment, read these operating instructions
carefully before using your scale.
Keep these instructions in a safe place.
– Do not expose the weighing instrument
to aggressive chemical vapors or to extreme
temperatures, moisture, shocks, or vibration.
– Exposure to excessive electromagnetic
interference can cause the readout value
to change. Once the disturbance has ceased,
the instrument can be used again in accor-
dance with its intended purpose.
– Do not use electrical equipment out of doors.
– The scale may not be operated in hazardous
areas or areas containing potentially explo-
sive agents. If you use electrical equipment
in installations and under ambient condi-
tions subject to stricter safety standards
than those described in the manual, you
must comply with the provisions as speci-
fied in the applicable regulations for
installation in your country.
– Make absolutely sure to disconnect the
scale from power (unplug the power cord)
before you connect or disconnect a periph-
eral device (printer or PC) to or from the
interface port.
– If you use cables purchased from another
manufacturer, check the pin assignments in
the cable against those specified by Sartorius
before connecting the cable to Sartorius
equipment, and disconnect any wires that
are assigned differently. The operator shall
be solely responsible for any damage or
injuries that occur when using cables not
supplied by Sartorius. Connect only
Sartorius accessories and options, as these
are optimally designed for use with your
PMA scale.
– The power connection must be made in
accordance with the regulations applicable
in your country. If you need assistance,
contact your Sartorius dealer or the Sartorius
Service Center. Any installation work that
does not conform to the instructions in this
manual will result in forfeiture of all claims
under the manufacturer’s warranty.
– If there is any indication that safe operation
of the equipment is no longer warranted;
for example, if the AC adapter is defective
or shows sign of damage, disconnect the
equipment from power and lock it in a safe
place to ensure that it cannot be used for
the time being.
– Disconnecting the grounding conductor
is prohibited. Make sure the applicable
accident prevention regulations are
observed by all operating personnel.
– Always make sure the equipment is discon-
nected from AC power before performing
any installation, cleaning, maintenance or
repair work on the scale or AC adapter.
If the equipment housing is opened by
anyone other than persons authorized
by Sartorius, all claims under the manufac-
turer’s warranty are forfeited.
– The casing on all connecting cables, as well
as the casing on wires inside the equipment
housing, is made of PVC. Chemicals that
corrode this material must be kept away
from these cables.
– Do not leave the interface port uncovered.
If the port is not used, or in preparation for
shipping, replace the cap to protect the data
interface from vapors, moisture and dust
or dirt.
– Never use a hammer to close a paint can
while is it still on the load plate, as this will
damage the weighing system.

Getting Started
§Unpack the scale carefully.
§After unpacking the equipment, please check
it immediately for any visible damage.
Equipment Supplied
– Scale
– Load plate
– Adapter cable
Setting up the Scale
Choose a suitable location where your scale will not
be exposed to drafts, heat radiation, moisture or vibra-
tions. Make sure to read these operating instructions
carefully before connecting the scale to power.
!Make sure to observe the safety instructions.
Leveling the Weighing Platform
Purpose:
– To compensate for uneven areas at the place of
installation
– To ensure that the equipment is placed in a perfectly
horizontal position for consistently reproducible
weighing results
Always level the weighing platform again any time after
it has been moved to a different location.
§Level the weighing platform using the four leveling
feet. Turn the feet until the air bubble is centered
in the level indicator.
§Check to ensure that all leveling feet rest securely
on the work surface.
> Each of the leveling feet must support an equal load.
> Adjusting the leveling feet:
To raise the weighing platform, extend the leveling
feet (turn counterclockwise). To lower the weighing
platform, retract the leveling feet (turn clockwise).
§Place the load plate on the scale.

Connecting the Scale to AC Power
The display and control unit is powered through the
scale’s power cord and power PCB.
§Plug the power cord into a wall outlet (mains).
!Make sure to observe the safety instructions.
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 do not match the rating or stan-
dard you use, please contact your Sartorius office
or dealer. Use only original Sartorius power cables.
Use of cables from other manufacturers, even if
these units have a registered approval rating from
a national testing laboratory, requires the consent
of a qualified electrician.
$If there is visible damage to the equipment or power
cord, unplug the equipment and lock it in a secure
place to ensure that it cannot be used for the time
being.
– Use only extension cords that meet the applicable
standards and have a protective grounding
conductor.
– Disconnecting the grounding conductor is
prohibited.

Operation
Scale Functions
Center an empty paint can on the load plate.
Press the Ukey (zero/tare; 3). The display shows 0.0 g.
Pour the first component of your formula into the can and
read off the weight when the stability symbol (in this
example, “g”) is displayed.
Add the other components up to the desired weight
(formula).
Remove the filled paint can from the load plate.
Never use a hammer to close a paint can while is it still on
the load plate, as this will damage the weighing system.
Press the Qkey (19) to
switch on the scale. A self-test runs automatically,
at the end of which the
readout shows 0.0 g.
If a different value is
displayed, press Ukey
to tare the scale.

Applications
Formulation (Calculation by a Factor)
The formulation program makes it easy to adjust your formulas for different final
quantities of a paint-mixing recipe (for example, to make 250 ml of a 1-liter recipe).
Press the Kkey (6) to select the desired factor. You can choose from the following:
0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 5.0 10.0 15.0 20.0 25.0.
Press the Rkey (18) (up) or
Skey (16) (down)
to modify the factor in in 1.0 steps for factors of 5.0 or more,
in 0.1 steps for factors of 1.0 to 5.0,
or in 0.01 steps for factors of up to 1.0.
Note:
A flashing arrow non the display indicates that the weight value displayed is not valid
in legal metrology (i.e., not legal for trade).
Example:
During formulation, the weight value is display in g. Let’s suppose you want to weigh
3 kg of a basic formula that is for a total amount of 1 l. With the recalculation mode,
you do not need to manually recalculate the individual components.
The basic formula for 1 liter is:
250 g first component
+ 250 g second component
+ 500 g third component
Total: 1000 g
1. Place the empty paint can on the load
plate and tare the scale. 2. Press the Kkey (6) repeatedly to set the
factor to 3 for this example.

9
Weighing Using the Recalculation Mode
Let’s suppose that you poured in too much of one color component for a given formula (in
this example, a 4-component recipe).
This example further assumes that you previously poured in all of the other amounts exactly
according to each of the values you entered and saved by pressing the Lkey [MEM] (9).
To correct for the overpour, press the Skey (16) to start the recalculation program; Cflashes
on the display. Use the Rkey (18; up) or Skey (16; down) to correct the value so that it
matches the amount called for in the formula. Then press L[MEM] (8) to have the scale
calculate the amount to be added for each of the components that were already poured.
The display shows the amounts required to correct the formula up to the point at which the
overpour occurred. After the correction has been completed, you can continue filling the
remaining components.
Note:
You can correct overpours as often as needed.
Keep in mind that the total quantity of paint at the conclusion of filling increases each time
you correct a component. Press the ckey (7) to check how much the total quantity will be.
The Cstands for “Correction factor.”
A flashing arrow non the display indicates that the weight value displayed is not valid in
legal metrology (i.e., not legal for trade).
3. 3.0 next to the weight readout.
4. Slowly pour in the first component until the
display shows 250 g
5. Pour in the second component until 500 g is
displayed.
6. Pour in the last component until 1000 g is
displayed
This concludes the recalculation example.
According to the display, exactly 1000 g was poured
in, but the paint can actually contains 3 kg by weight
in accordance with the factor you selected (3).
The procedure is the same for any other conversion
factor.
