I was prompted by a discussion in another thread on this forum to buy one of
those contactless IR thermometer guns. It is an IR4890 by IWH.
I tried to measure the temperature of a surface mount resistor. The
thermometer shows about 25 to 26C but the resistor is hot enough to cause me
to immediately remove my finger from it.
The thermometer works on some other objects but has trouble with the PCB
solder mask and surface mount resistors. Can anybody explain this?
Thanks,
John
