Appendix B Free Programming
Free Programming is an advanced option for entering original
user-developed methods. When the Free Programming option is
selected, an overview of the specifications of the programmed test
is displayed. Each input option can be modified to develop the user
method. Refer to
Table 15 for more information. To modify an input
option, select the appropriate line and press
EDIT
.
Important Note: Perform steps 1–6 of Programming a New User
Method (
section 6.1.1 on page 48 ) before proceeding with Free
Programming.
B.1 Measurement Process
The measurement process defines the handling and the
measurements of the test:
• At which and how many wavelengths should measurements
be performed?
• How many absorbance measurements must be performed?
• When should the zero measurement and the sample
measurement be performed?
• Are waiting times necessary between measurements?
• Should individual program sequences be repeated?
The elements of a measuring sequence, such as zero and sample
measurements, and the timer(s) (reaction times, waiting times, etc.)
are individually defined.
Table 15 Free Programming Options
Input Option Description
Name Name of the analysis parameter.
Version An abbreviation or version number assigned by the user is entered here.
Measurement Process
Exact definition of the test: the number of wavelengths at which measurements are made, the
number of absorbance measurements needed, the keys to be used, any waiting periods between
measurements, etc.
Formula Definition of the formulas with which the test result is calculated.
Variables
The number of variables shown in the display depends on the definition of the measurement process
and the formulas. Input of the numerical values of the wavelengths, factors, constants, etc.
Timer 1, Timer 2,
Timer 3, Timer 4
Used to enter abbreviations and defined times for up to four timers. Activate the appropriate line and
touch
EDIT. The timers are activated or deactivated with the control boxes on the left of the display.
In the next column, a selection can be made from a list of names that describe the corresponding
work step. In the third column, the times for each active timer are entered.
