allows quick connecting with all available accessories.
The following procedure could help you for installing your
IRtec Rayomatic
thermometer.
•
Configure the thermometer. Set the emissivity on the
IRtec Rayomatic 20
moving the 2 rotative switches.
Connect the
IRtec Rayomatic 40
to the PC and set the mathematical function, the emissivity and the
temperature range by software.
•
Connect, if necessary, all accessories (air purge, support, sighting tube, etc.). Fix the IRtec Rayomatic to the
process.
•
Connect the signal cable from your data acquisition system to the instrument terminals. Pay attention to the
polarity.
•
Aim accurately the thermometer to your target. Refers to Target vs. distance table on section 1. Be sure that
your target is bigger than the measuring area. The optional laser pinpointing can help you for best
