ABSTRACT:
A temperature monitoring system provides a first, coarse temperature output signal, and a second, fine temperature output signal based on the first, coarse output signal. The fine output signal has a higher resolution than the coarse output signal, and permits fine temperature control of an apparatus at a variable control output. The fine output signal is automatically calibrated upon switching from the coarse to the fine signal.
