Operating Tips - General IRTC40 Mode D'emploi

OPERATING TIPS

The first few times you use the IRTC40 in
Scan mode, don't be too concerned about
which setpoint bandwidth to choose. With
experience you will learn whether a narrow
(1°F/0.5°C), normal (5°F/3°C) or wide
(10°F/5.5°C) value of 1/2 T is best for
your particular application. As part of your
education, note the effect of changing
setpoint bandwidths. For example, widen
the bandwidth from 1°F to 5°F and note
that some targets that caused the LCD
backlight to glow red before produce a
green backlight now.
Remember that the reference temperature
you acquire and the setpoint bandwidth you
choose disappear if you allow just one
minute to go by without pulling the trigger.
For this reason, you can expect to repower
the IRT often.
The diagram on the next page illustrates the
8:1 distance-to-spot (D:S) ratio (field of
view) of the IRTC40. To ensure that your
measurements accurately represent target
temperature, move the IRT close enough to
