72Advanced Operations6.1.2 Free programming program typeFree Programming is an advanced option for entering originaluser-developed methods. When the Free Programming option isselected, an overview of the specifications of the programmed testis displayed. Each input option can be modified to develop the usermethod. Refer to Table 10 for more information. To modify an inputoption, select the appropriate line and press Edit.Important Note: Perform steps 1–6 of Programming a New UserMethod (section 6.1.1 on page 61) before proceeding with FreeProgramming.Highlight the line containing the program point that is to be edited ordefined and press Edit.6.1.2.1 Measurement processThe measurement process defines the handling and themeasurements of the test:• At which and how many wavelengths should measurements becompleted• How many absorbance measurements must be completed?• When should the zero measurement and the samplemeasurement be completed?• Are waiting times necessary between measurements?Table 10 Definitions of the program pointsProgram point DescriptionName Name of the analysis parameterVersion An abbreviation or version number assigned by the user is entered here.Measurement ProcessExact definition of the test: the number of wavelengths at which measurements are made, thenumber of absorbance measurements needed, the keys to be used, any waiting periods betweenmeasurements, etc.Formula Definition of the formulas with which the test result is calculated.VariablesThe number of variables shown in the display depends on the definition of the measurementprocess and the formulas. Input of the numerical values of the wavelengths, factors, constants,etc.Timer 1, Timer 2,Timer 3, Timer 4Used to enter abbreviations and defined times for up to four timers. Highlight the appropriate lineand press Edit. The timers are activated or deactivated with the control boxes on the left of thedisplay. In the next column, a selection can be made from a list of names that describe thecorresponding work step. In the third column, the times for each active timer are entered.
