Operation 23
CTC100 Programmable Temperature Controller
Raising the heater output by Step Y significantly increase the temperature, in which
case Step Y should be increased;
The Lag time for the heater to respond, in which case it should be
increased; or
The temperature was drifting up or down as the test began, in which case the heater should
be left to stabilize at room temperature before trying to tune again.
During the first stage of autotuning, the CTC100 compares how much the
temperature changes before vs. after turning the heater on. Autotuning is
10x more after the heater is
turned on.
w or otherwise use the CTC100 during tuning; tuning will
continue unless you turn tuning off or disable the outputs with the Output Enable key.
good idea to display a graph of heater output and temperature while autotuning (select the two
channels, press the Show Data key,
). To see the status message
Setup , select the tab for the output channel, and then
button in the bottom-right corner.
When tuning is finished, the CTC100 beeps and the PID feedback is automatically enabled. If the
temperature is still below the setpoint, the CTC100 starts increasing power to the heater. The
temperature may overshoot the setpoint, but should eventually stabilize at the setpoint.
The feedback should be re-tuned when:
here is a large change in the temperature
The temperature units are changed (e.g. from °C to °F)
The output units are changed (e.g. from W to A)
The lowpass filter setting is changed
