range the sensor would be defective, but
at the 20KΩ range it would test good.
Now set the multimeter to the 2KΩ range.
(See Fig. 6) The
display will indi-
c a t e a n
overrange con-
dition because
3.87KΩ is larger
than 2KΩ.
This example
shows that by
decreasing the
range you in-
crease the ac-
curacy of your
measurement.
