6.1.2 Free programming program type
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 10 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 61) before proceeding with Free
Programming.
Highlight the line containing the program point that is to be edited or
defined and press Edit.
6.1.2.1 Measurement process
The measurement process defines the handling and the
measurements of the test:
• At which and how many wavelengths should measurements be
completed
• How many absorbance measurements must be completed?
• When should the zero measurement and the sample
measurement be completed?
• Are waiting times necessary between measurements?
Table 10 Definitions of the program points
Program point 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. Highlight the appropriate line
and press 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.
