A silicon diode-connected transistor has a temperature coefficient of
about -2mV/
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.
The LM339 is required to
ensure logic compatibility
with heavy display loading.
