OPERATING
INSTRUCTIONS

CONVENTIONAL IRT MODE

1. Power on the IRTC40 by squeezing and
holding the yellow measurement trigger.
(If the LCD does not illuminate, the
battery is dead and must be replaced;
see p. 11 for instructions.) The LCD will
illuminate with a green backlight and the
term SCAN on the top line. The only
pointer visible on the bottom line of the
LCD will be the one above OFF. A red
laser pointer will be visible exiting the top
front of the gun.
2. Continue squeezing the trigger while
using the laser pointer to target surfaces
at different temperatures (windows, light
bulbs, your hand, etc.). Note that the
temperature readout will track changes
in temperature in the default
measurement unit of °F.
3. Release the trigger. Immediately, the
beeper will sound three times and the
term SCAN will disappear. Fifteen
