Electronic paint-mixing scales

Example:
Let's suppose you want to weigh only 250 l of a basic formula 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 tare.
4. Slowly pour in the first
component, "250 g" of
green paint, until the
display shows
"250 g".
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, .25.
Follow the same procedure for any other conversion factor.
Weighing Using the Recalculation Mode (Model PMA35D-X000C Only)
Let's suppose that you poured in too much of one color component for a given formula (e.g., with 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 value given in the
formula. Then press the y key (3) to start 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. This will ensure 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. Press the [REC] key (8) to check how
much the total quantity (in liters) will be. The arrow n on the display means that the weight shown is
not valid for use in legal metrology (not legal for trade).

2. Press the v key (7)
once.
5. Pour in the second
component, "250 g" of
red paint, until
"500 g" is displayed.
3. "25 " is displayed next
to the weight.
6. Pour in the last
component, "500 g" of
blue paint, until "1000 g"
is displayed.
