ABSTRACT:
The disclosure relates to a method and apparatus for on-line calibration of disc thermostats. A disc thermostat is initially provided in assembled condition, the gap at the switch measured and compared with a predetermined optimum gap, the error magnitude determined and a device operated to alter the position of the disc and transfer element relative to the switch to provide the predetermined optimum gap. A feedback generator station tests a prior thermostat during disc snapping for disc velocity and switch opening and provides a fine tuning adjustment signal to alter the predetermined optimum gap on-line.
