Performance Example

Typical stabilization characteristics.

The green line is the temperature setpoint which is stepped in several intervals of a typical experiment from −50 °C to 200 °C. The red line shows the sample temperature (process value).

As can be seen, temperature stabilization is very accurate without any visible overshooting and fast. Typical stabilization time is 3 to 5 minutes per step.

After each stabilization, a dielectric or impedance measurement sweep is started. After sweep completion the subsequent temperature setpoint is set.
