TO DISPLAY
A sillicon diode-connected transistor has a temperature coefficient of about -2mV/
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
.
