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 I key (6). The display shows “0.00 g.”
Place an empty paint can on the weighing pan (11).
Press the U key (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 zero the display by pressing the tare key,
and then press the I key (6) to toggle to the second
decimal place with a resolution of 0.05 g, you can
continue weighing 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 value 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 green paint
+ 250 g red paint
+ 500 g blue paint
Total: 1000 g
10
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.
11
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 flashing arrow
n in the display means that the weight value 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” of green
paint, until the display shows “250 g.”
5. Pour in the second component, “250 g” of red
paint, until the display shows “500 g.”
6. Pour in the last component, “500 g” of blue, until
“1000 g” is displayed.
3. Pour in the first component.
+ 50.0 g
2. Press the U key (5)

16. Press the L key [MEM].
The scale will automatically
return to the formulation
program. “C” disappears.
+ 200.0 g.
17. To check the prospective
total weight, press the c
key (8) [REC].
“C” = Correction factor; in
this example, 1.02. (Total
formula weight + correction factor = total weight)
