Furthermore the crrest-factor is explained and how it can
There remain some error-sources even with a good True-RMS AC+DC multimeter which will be investigated in Pt.2 of this video.

The poor-man´s Infrared Imaging-Camera :-)
Roger explains how an electronic Infrared-Thermometer (or Pyrometer) works and what traps there are when taking measurements with them.
Why is a high Spot-to-Distance ratio of the IR-lens important?
What is the optical parallax of the laser-pointer?
What is the emissivity-factor and when can it give false measurements?

Very useful if you have a solder-station/solder-iron of unknown quality to check the true temperature at the solder-tip.
For the FG-100 there are also temperature-probes for solder-pots and for hot-air stations available.
Furthermore a teardown of the FG-100 & comparison with the ELV LTT1 and a normal thermocouple thermometer.
