3. Measurement Lock mode—Pressing the Mode button
three times with the IRT powered on causes the word
LOCK to appear blinking on the top line of the display.
Pressing the Meas. (measure) button changes LOCK from
blinking to constant, indicating operation in Measurement
Lock mode.
In this mode, you need not hold the Meas. (measure) button
while scanning. Surface temperatures are measured and
displayed in real time, and the IRT's 15-second auto power
off function is disabled. Although Lock mode makes
scanning easier, it has a potential downside: the disabling of
auto power off. If you forget to exit Lock mode and then
leave the IRT105 powered on for a long time, you run the
risk of discharging the thermometer battery. So remember to
exit Lock mode after using it by pressing the Mode button.
Note that the laser pointer does not turn on or remain on
when you enter Lock mode—even when the laser's default
state is on. This is a safety precaution related to the
disabling of the auto power off function. If the user were to
leave the IRT unattended after putting it into Lock mode, a
curious child could enter the room and stare directly at the
pointer to investigate the source of the unusual light.
4. °C/°F Selection mode—Pressing the Mode button
four times with the IRT powered on causes the symbol of
the current default temperature unit (°C or °F) on the right
side of the display to change from constant to blinking.
Pressing the Meas. (measure) button while the term is
blinking switches all displayed readings to the other unit
until the default unit is changed again.
5. Emissivity Selection mode—Pressing the Mode button
five times with the IRT powered on causes the Greek letter
