Press the
Abs/Variables
key to select, from the
displayed list, the required element of the defined
measuring sequence and therefore the corresponding
reading wavelength, so that this can be taken into
account in the formula.
Zn represents the zero measurement at wavelength n,
Rn the measurement at wavelength n, Fn the factors for
calculation and Un the factors for conversion, for
example between two different chemical formulae.

to enter a mathematical operation.
Select the operation and press
OK
to confirm.
The available choice of mathematical operations
depends on the defined formula.
This means that functions such as "
( )
" or "
ln
"/"
log
" etc.
are only active if a term in parentheses or the calculation
of a logarithm is mathematically permissible in the
defined formula (this also applies to the basic
mathematical operations).
The following mathematical operations are available:
•
+ (Addition)
•
- (Subtraction)
•
(Division)
•
× (Multiplication)
•
^ (Exponent)
•
Ln (Natural logarithm)
•
Log (Common logarithm)
