Operation

Weighing with One Decimal Place

Place an empty paint can on the weighing pan.
Press the tare key U (5). The display shows “0.0 g.”
Pour in the first component, and read off the weight as
soon as the stability symbol appears; in this case, “g.”
Pour in additional components until the desired weight
of your formula is reached.
Remove the filled paint can from the weighing pan.

Never use a hammer to close the lid of a paint can
while it is still on the weighing pan.
Otherwise, you will damage the weighing system.

Turn on the scale using the
Q key (2).

After the scale has been
turned on, it will automati­cally run a self-test.
At the end of this test, 0.0 g
is displayed.

If a different readout is
displayed, zero or tare the
scale using the tare key
U (5).

8

Weighing with Two Decimal Places

Note:
To weigh using two decimal places, you must first
adapt the settings (refer to the chapter entitled “Menu
Settings”)

Press the toggle key I (6). The display shows “0.00 g.”

Place an empty paint can on the weighing pan (11).

Press the tare key U (5). The display shows “0.00 g.”

Pour in the first component: 205.50 g.
Read off the weight as soon as the stability symbol
appears; in this case, “g.”

Pour in additional components until the desired weight
of your formula is reached.
Remove the filled paint can from the weighing pan.

Important Note:

If you tare the scale, and then press the toggle key I (6)
to toggle to the second decimal place with a resolution
of 0.05 g, you can continue weighing with two decimal
places up to 999.95 g.
For weights exceeding 999.95 g, only one decimal place
will be displayed.

Never use a hammer to close the lid of a paint can
while it is still on the weighing pan.
Otherwise, you will damage the weighing system

Applications

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).
You can select various factors (amounts) by pressing the K formulation key (7):

0.25 0.5 0.75 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 5.0.

By pressing the R key (3): upwards
or S key (4): downwards,
you can alter the value – in 0.1 increments, as of factor 1.0
or – 0.01 increments, from factor 0.25 to 1.0.

Important Note:

The flashing arrow

n on the display means that the weight shown is not verified for use

in legal metrology (not legal for trade).

Example:

As you pour in the components of your formula, the weight is displayed in “g.”
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 1

st

component

+ 250 g 2

nd

component

+ 500 g 3

rd

component

Total: 1000 g

1. Place the empty paint can on the
weighing pan and tare (zero the display).

2. Press the K formulation key (7) several
times to select the conversion factor “.25”
used in this example.

10

We have come to the end of our example. According to the display, exactly 1,000 g was
poured in, but the paint can actually contains only 250 g by weight according to the factor
you selected, .25. Follow the same procedure for any other conversion factor or to convert
a 1-gallon formula into quarts.

Weighing Using the Recalculation Mode

Let’s suppose that you poured in too much of one color component for a given formula
(e.g., one consisting of 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 stored by pressing the L key [MEM] (9).
Press the S key (4) to start the recalculation program. “C” will begin flashing on the display.
To correct the weight displayed to the same value you entered for the given formula, either
scroll upwards using the R key (3), or downwards using the S key (4). When you then press
the L key [MEM] (9), the scale will automatically calculate and display the amounts of paint
in “g” to add for each of the other components that you already poured in. This mode thus
ensures that the total result of your formula for these components will be correct.
After pouring in these amounts, you can continue to add the remaining components of your

formula.

Important Note:

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. Therefore, press the c key
(8) to check how much the total quantity (in liters) will be. (“C” = correction factor)

The arrow

n in the display means that the weight shown is not verified for use in legal

metrology (not legal for trade).

3. “.25” is displayed next to the weight

4. Slowly pour in the first component, “250 g” until
the display shows “250 g.”

5. Pour in the second component, “250 g” until the
display shows “500 g.”

6. Pour in the last component, “500 g” until “1000 g”
is displayed.

3. Pour in the first component.

+ 50.0 g

2. Press the U key (5)

0.0 g

Example (cumulative):

1. Place an empty paint can on

the weighing pan (11).
+ 118.0 g

4. Press the L key [MEM] (9).

STO 01

5. Pour in the 2nd component.

+ 110.0 g

6. Press the L key [MEM] (9).

STO 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 y key (4) to start

the recalculation mode.
A “C” = correct flashes on
the display

9. Press the y key (4) several

times to correct the value to:
+ 200.0 g

10. Press the L key [MEM] (9)

COR 01

11. 1. Add the first component.

“C1” is displayed –1.7 g

12. Pour in paint until 0.0 g is

displayed.

0.0 g

13. Press the L key [MEM] (9)

COR 02

14. Add the second compo-

nent. “C2” is displayed.
–2.0 g

15. Pour in paint until the

value 0.0 g is obtained

0.0 g

16. Press the L key [MEM].

The scale will automatically
return to the formulation
program “C” disappears.
+ 200.0 g

17. To check the total weight,

press the c key (8) [REC].
“C” = Correction factor, in
this example 1.03.
(Total formula weight +
correction factor = total
weight)

18. Add the fourth component

+1000.0 g

We have come to the end
of our example.

Calibration/Adjustment

You can calibrate/adjust the scale by pressing the
tare key U (5).
To do so, menu code 1 5 1 must be selected.

Calibration weight: 5,000 g; accuracy: + 0.075 g.

After connection to AC power and before each
calibration/adjustment, allow the scale to warm up
for approx. 30 min.

Hold down the tare key U (5). for 2 sec. When
5000 is displayed, release the key.
