Your hand will produce enough heat to change the resistance, but use a heat
gun or hair dryer. Use a digital multimeter to see the change. This will
only tell you if the thermister is working and not dead. It will not tell
you if it is accurate.
Room temp (70degF) resistance should be around 5 to 6 Kohms. See Lew
Rishel's graph for change in resistance with temp.

> I'm sure somewhere there is a test to see if a thermistor is working or
not before installing it in a car. Probably something to do with resistance
when it is heated. I have three of them in the stash and want to do a simple
bench check before declaring them junk or OK to keep in the stash.

use? Will a simple match produce enough heat to move a meter?
