TO BACKPLANE
TO DISPLAY
A silicon diode-connected transistor has a temperature coefficient of
about -2mV/°C. Calibration is achieved by placing the sensing
transistor in ice water and adjusting the zeroing potentiometer for a
000.0 reading. The sensor should then be placed in boiling water and
the scale-factor potentiometer adjusted for a 100.0 reading.
