Purpose
With this application program you can
calculate a weight value using an alge-
braic equation. This can be used, for
example, to determine the gsm weight
(grams per square meter) of paper.
You can use the "Calculation"
application in combination with
a program chosen from Application 2
(checkweighing, time-controlled
functions) and one from Application 3
(totalizing, formulation, statistics) as
well as the extra functions.
Available Features
– You can store an equation and
configure the Setup menu to initialize
this program automatically with the
stored equation (Setup: App: Basic
settings : Auto start upon initialization:
On)
– The o symbol is displayed to indicate
a calculated vale. The equation used is
displayed in the text line
– If no equation was entered, the weight
value is displayed
– Toggle between the weight readout,
equation input and display of the calcu-
lated result by pressing the correspon-
ding soft keys (or press c to toggle
between weight and calculated value)
– The are four operators (+, –, *, /) and
one factor (weight value) available when
you enter an equation
– Max. equation length: 28 characters
– Pressing c will delete either the
equation or the last character entered,
depending on the configuration in the
Setup menu (Setup: Device: Keys: CF
function for input: Delete last character)
– The calculated result is displayed
with the number of decimal places
configured in the Setup menu. Not all
decimal places are displayed if the result
is longer than the display allows.
If there are more digits before the
decimal point than the display can
show, an error message is displayed.
– The equation is stored in non-volatile
memory
