1. MAX Measurement mode—To identify the hottest surface in
an environment, press the Meas. button to power on the IRT.
Then (within 15 seconds) press the Mode button once. This
will cause the text MAX to appear blinking on the top line of
the display. Then press the Meas. (measure) button. This
changes MAX from blinking to constant, indicating operation
in MAX Measurement mode.
Within 15 seconds, press and hold the Meas. (measure)
button and begin to scan surfaces within sight. Note that in
MAX mode the display no longer tracks the temperatures of
scanned surfaces in real time. Instead, it shows the highest
temperature measured since the Meas. (measure) button was
pressed. Also note that the maximum temperature is held
only for 15 seconds after the Meas. (measure) button is
released, causing the IRT to begin counting down to auto
power off.
To exit MAX mode and return to real-time temperature
scanning, press the Mode button. If the IRT auto powers off
while in MAX mode, it will not resume operation in MAX mode
when powered on again. It will resume operation in real-time
measurement mode.
2. MIN Measurement mode—The flip side of MAX mode, MIN
mode is entered by powering on the IRT105 and pressing the
Meas. (measure) button twice. This causes the text MIN to
appear blinking on the top line of the display. Pressing the
Meas. button changes MIN from blinking to constant,
indicating operation in MIN Measurement mode.
In MIN mode, the display shows the lowest temperature
measured so far during a scanning session. Like MAX values,
MIN values are held for only 15 seconds. To exit MIN mode
and return to real-time scanning, press the Mode button.
