Important ote to Users
GMake sure to carefully read and follow
sections marked with this symbol.
They contain important safety instructions
and information.
GUse only the adapter that is included in
delivery (part no. 6965619) to connect a 9-pin
connecting cable to the 25-pin data interface

Getting Started
Remove the scale, load plate
and AC adapter from the
package.
Immediately after unpacking the
equipment, check it for any
visible damage.
Equipment Supplied:
Scale, load plate,
AC adapter, data cable
(25– pin to 9-pin)
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.
Choose a suitable place to set up the scale. Avoid exposure to
drafts, heat, moisture and vibration.
GDo not operate the equipment in a hazardous area/location.
Check that the voltage rating of the AC adapter matches that of your
local line voltage (mains supply).
G If it does not match your local line voltage, contact your Sartorius
office or dealer.
Use only original Sartorius AC adapters.
DC jack on the scale. Remove the load plate.
Use a 13-mm open-end wrench
to loosen the leveling foot (1).
Turn the leveling foot (2) until
the scale is level. Tighten the
lock nut (1) with the wrench.
Replace the load plate.
Always allow approximately
30 minutes warm-up time after
connecting the scale to AC
power.

Operating the Scale
Press the ekey (2) to turn the
scale on.
A self-test is run automatically.
At the end of this test, 0.0 g is
displayed.
If a different readout is
displayed, press the =key
(4) to tare the scale.
Weighing with One Decimal Place
Place an empty paint can on the load plate (1).
Press the =key (4). The display shows “0.0 g“.
Pour in the first component, and read off the weight as soon as the
stability symbol, in this case “g,“ is displayed.
Pour in additional components
until the desired weight (formulation) is reached.
Remove the filled paint can from the load plate.
GNever close the lid of a paint can
while it is still on the load plate, as
this will damage the weighing
system.
Calibration/Adjustment
If the scale is not being used in legal metrology, you can calibrate/adjust the scale by pressing the
=key (4). Calibration weight: 10 kg; accuracy: M1.
Always allow approximately
30 minutes for the scale to
warm up after connecting it to
AC power and before
performing calibration/
adjustment.
Press the = key (4) for 2
seconds; “10000“is
displayed. Release the key.
Center the calibration weight
on the load plate (1).
Calibration/adjustment is
performed automatically. After
calibration/adjustment, remove
the calibration weight.

6. Pour in the last
component, “500 g“ of
blue paint, until “1000 g“
is displayed.
5. Pour in the second
component, “250 g“ of
red paint, until
“500 g“ is displayed.
4. Slowly pour in the first
component, “250 g“ of
green paint, until the
display shows
“250 g“.
3. “ 25 “ is displayed next
to the weight.
Formulation Mode (Calculation by a Factor)
This mode enables you to weigh in amounts that are smaller or larger than that of your basic formula
for a specific paint color (e.g., 250 ml of a 1-l formula), without having to do any manual
recalculation.
You can select from among the following factors (amounts) by
pressing the vkey (7):
0.5 1.0 2.0 5.0 10 15 20 25
As you pour in the components of your formula, the weight is displayed in “g.”
ote:
The flashing arrow non the display means that the weight shown is not valid for use in legal
metrology (not legal for trade).
Example:
Let’s suppose you want to weigh only 250 ml 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 green paint
+ 250 g red paint
+ 500 g blue paint
Total: 1000 g
1. Place the empty paint can
on the load plate and
press the =key (4).
2. Press the vkey (7)
once.
We have come to the end of our example. According to the display, exactly 1000 g was poured in,
but the paint can actually contains only 250 g by weight according to the factor you selected, 0.25.
Follow the same procedure for any other conversion factor.

6
Weighing Using the Recalculation Mode (Model PMA35D-000C Only)
Let’s suppose that you poured in too much of one color component for a given formula (e.g., 4
components). In addition, let’s assume that you previously poured in all of the other amounts exactly
according to each of the values you entered and saved by pressing the [MEM] key (9). Use the
correction keys, y(3) and Y(10), to correct the weight displayed to the same value you entered.
Since you overpoured in this case, press the ykey (3) to decrease the readout. This starts the
recalculation mode; “C” flashes on the display. The scale automatically calculates and displays the
amounts in “g” to add for each of the other components that you already poured in, so that the total result
of your formula for these components will be correct. After adding each component, press the [MEM] key
(9) to display the next . After pouring in these amounts, you can continue to add the remaining
components of your formula.
Important ote:
You can correct an incorrect amount any number of times. However, the total (liter) quantity in the paint
can will increase each time you correct a component. Press the [REC] key (8) to check how much the
total quantity (in liters) will be. The arrow non the display means that the weight shown is not valid for
use in legal metrology (not legal for trade). Example:
1. Place an empty paint can
on the load plate (1).
+ 118.0 g
2. Press the =key (4).
0.0g
3. Pour in the 1st component.
+ 50.0 g
4. Press the [MEM] key (9).
ST 01
5. Pour in the 2nd component.
+ 110.0 g
6. Press the [MEM] key (9)
ST 02
7. Pour in the 3rd component.
+ 203.0 g
Oops! You poured in too much.
The correct weight for the
formula is 200.0 g.
8. Press the ykey (3) to
start the recalculation mode.
A“C” (= correct)
flashes on the display.
9. Press the ykey (3) to
correct the value to:
+ 200.0 g
10.Press the [MEM] key (9)
ST 03
11. Add the 1st component;
„C1“ flashes on the display.
– 1.7 g
12. Fill to 0.0 g.
0.0 g
13. Press the [MEM] key (9)
ST 01
14. Pour in the 2nd component;
“C2” flashes on the display.
– 2.0 g
15. Fill to 0.0 g.
0.0 g

16. Press the [MEM] key (9);
the scale now automatically
returns to the formula weighing
mode.
+ 200.0 g
17. Press the [REC] key (8) to
check what the total
weight will be
“A“ = Amount
(displayed in liters)
A 1.03
18. Pour in the 4th component.
+1000.0 g
We have come to the end of
our example.
Accessing the Menu
Press e (2) to turn off the scale. Press eagain to turn the scale
back on; briefly press the =key (4) during the automatic self-test.
“I“is now displayed. Set the desired code as follows:
§Press =(4) until the desired number is displayed.
§Press w(6); the middle number appears.
§Press = (4) until the desired number is displayed.
§Press w (6); the third digit appears.
§Press (= (4) until the desired number is displayed.
§Then press w (6) for 2 seconds until “o“ appears. This symbol
indicates that the new code has been set.
§Hold down = (4) for 2 seconds until an automatic self-test is run.
§Then release this key. The new code is now saved.

Care and Maintenance
Cleaning
Use only naphtha or alcohol to clean the scale.
G Do not wash down the scale with water or dry it with compressed air.
Safety Inspection
G If there is any indication that safe operation of the scale with the AC adapter is no longer warranted,
turn off the power and disconnect the equipment from AC power immediately. Lock the equipment in a
secure place to ensure that it cannot be used for the time being. In this case, notify your Sartorius office,
dealer or paint supplier. Only service technicians who are authorized by Sartorius and have access to
the required maintenance manuals are allowed to perform maintenance and repair work on the
equipment.
Safe operation of the equipment is no longer ensured when:
- there is visible damage to the equipment
- the equipment no longer functions properly
Always unplug the scale before connecting peripheral equipment. You can choose the 9-pin or 25-pin
data output port.
