Exercise 1: Gradually vary the Offset in the Signal Generator between 0.5°C and 2°C.

How is the reference temperature, Tr, in the Temperature (C) scope is set? Attach a

sample temperature response.

Exercise 2: Vary the relay amplitude, Vh_amp, in the Control Parameters section.

Explain how the heater voltage affects the temperature variations and, in particular,

observe the frequency and amplitude of the chamber temperature. Attach a

representative temperature response.

Exercise 3: Explain the effect of changing the relay mean, Vh_off. Attach a temperature

response.

➤ Exercise 4: Examine the effects of changing the relay width (or hysteresis). DTh.

between 0.01°C and 1.00°C. Give a short explanation and attach a temperature response

with a narrow and wide hysteresis.
