Do one of the following: • Type a formula in the Formula field. • Select formula components from the Operators, Parameters, and Functions drop-down lists. When you select a component, the system displays it in the Formula field. 8. To test the formula, select Check. If there are no problems, the system displays “Syntax OK!”. If there are any problems with the formula, the system displays an Error message in place of the Formula field label. 9. When the formula is correct, select OK to save it.

(continued)For example, when a Volume formula is created:
Vol [ml or cm3] = 0.523598*{D1}*{D2}*{D3}
(D1, D2, and D3 indicate a measurement result.)
In this case, the measurement (D1, D2, and D3) is a distance
measurement, so the measured data is a meter [m] unit
according to the above table.
To change into a milliliter, the system multiplies each
measurement value by 100. As a result, it multiplies a formula
by 1,000,000.
The standard unit of volume is a cube meter, so the system
multiplies the result by 1,000,000.
The system multiplies the calculation result by the coefficient
and converts it. To get a correct result, when you define the
formula, you must convert the coefficient itself, such as the
coefficient of 10^.
For example, if you want to define the following formula:
efg[g] = 10^(1.5662-
0.0108*{P1}+0.0468*{P2}+0.171*{D1}+0.00034*{P1}*{P1}-
0.003685*{P2}*{D1})

Conversion
(continued)The system defines the standard value of each measurement as
a meter [m]. If the unit of each measurement value of this
formula is defined as centimeter [cm], you must define the
formula as follows:
efw[g] = 10^(1.5662-0.0108*{P1}*100 + 0.0468*{P2}*100 +
0.171*{D1}*100 + 0.00034*{P1}*{P1}*100*100 -
0.003685*{P2}*{D1}*100*100)
(This converts each measurement value to a centimeter [cm],
since the system standard unit is a meter [m].)
The output unit of this formula is a gram. Since the standard unit
of the system is defined as a kilogram [kg], the system multiplies
the output by 1,000.
Because the output of this formula is defined as a gram, it is
necessary to define the formula as follows.
efw[g] = 10^(1.5662-0.0108*{P1}*100 + 0.0468*{P2}*100 +
0.171*{D1}*100 + 0.00034*{P1}*{P1}*100*100 -
0.003685*{P2}*{D1}*100*100)/1,000
As shown, you can obtain an exact calculation result.
