Programs
Overview
This section provides instructions and examples for creating a program for Ahiba
IR. Keep in mind the following:
•
The local memory can accommodate up to 99 programs.
•
A program can include a maximum of 15 steps.
•
A step defines a temperature, gradient, speed, or hold (time).
A HOLD is generally used when the program requires operator intervention. A
hold can be included as a program step, or can be inserted manually at run time.
See also Running a Program, Program Holds for a detailed discussion of this
option.
Limit Values
When entering data for a program, all entries are checked against the following
limits to ensure they are within the operating range of the machine:
Parameter
Limit Value
TEMPERATURE
(Processing
temperature
+20°C +140°C
+77°F +284°F
TIME (minutes)
0 – 180 min
GRADIENT
-5.0°C +5.0°C/min
SPEED
5 – 50 rpm
HOLD
0 1
Units equipped with a 5L drum should limit the heating gradient input to
2.5°C/min, this due to the mass of the beaker and to prevent “Temperature
out of Range” errors.
