OPERATING INSTRUCTIONS
TARGETING LASERS
The IR10 features dual lasers
8
to assist in targeting the measurement area.
The distance between the two laser spots on the surface of the object being
measured approximates the diameter of the circular measurement area from
which the infrared sensor is collecting data. Measurement areas located far
away from the meter will be larger than those close to the meter. Press and
hold the SET button
2
to activate/deactivate the targeting lasers
8
.
When on, the laser icon
B
will appear on the display
4
. NOTE: Lasers are
automatically disabled when measuring using the K-type probe
9
.
The meter is configured with 20:1 optical resolution (distance-to-spot
ratio). The distance-to-spot ratio defines the size of the measurement
area relative to the distance between the measurement location and the IR
sensor
7
. Typical diameters of the measurement area as a function of the
distance between the meter and the target area are depicted below for 20:1
optical systems (Fig. 1).

IR TEMPERATURE MEASUREMENTS
By default, IR10 measures temperature by sensing IR emission
7
from
surfaces. Pull the trigger
5
and aim the targeting lasers
8
at the object
to be measured to initiate a measurement event. The meter will continue to
sample while the trigger is held depressed. Releasing the trigger ends the
measurement event. The results are held on the display for 15 seconds and in
the absence of other activity, the meter automatically powers off (APO).
K-TYPE PROBE MEASUREMENTS
K-type probe measurements are active whenever the probe is inserted into
the K-Type Probe Jack
9
. K-Type will be illuminated on the display
4
,
and the IR measurement functions will be disabled. Pull and release the
trigger to initiate a measurement event. A subsequent pull of the trigger ends
the measurement event. If a measurement event is not ended via a trigger
pull, it times out and ends automatically after 10mins. At the end of the
measurement event, the results are held on the display
4
for 15 seconds
and in the absence of other activity, the meter automatically powers off (APO).
