4.7 Using the sweep function
4.7.1 The purpose of the sweep function
The sweep function allows the set point to be programmed to follow a fixed temperature versus
time profile. The profile consists of a series of constant temperature steps joined by linear
ramps.
During a sweep, the system updates the temperature set point every 100 mSec.
A program can contain as many sweeps and steps as required. Each sweep and step lasts for a
programmable time period. Once a sweep has been programmed, it can be repeated as often
as desired. It is also retained in non-volatile memory when the iTC is switched off.
The Auto-PID facility may be used in conjunction with the sweep function to provide optimum
control over a wide temperature range. To avoid discontinuities during a sweep, it is
recommended that the start and end temperatures for the sweep coincide with Auto-PID
segments.
