TEMPERATURE
MEASUREMENTS
The program
was
written for 2-wire resistance measurements
which provides ac-
curate
results if the thermistor
is used at a temperature
where
its resistance
is
much
greater than the resistance of the test leads. For greatest accuracy from a
thermistor, 4-wire resistance should be made. To change from the 2-wire mode to
4-wire mode, change line 15 to read XEQ "M40HM".
This program is useful over
a range of —80°C
to + 150°C.
