TEMPERATURE MEASUREMENT
To measure temperature with the IR5, aim the meter at the object to
be measured, pull the trigger
seconds. Releasing the trigger initiates Data Hold, "HOLD" will show
on the display, and the measurement will be held on the display.
If the display shows "OL" or "–OL" following a measurement, this
indicates that the surface temperature of the object being measured
is either above or below the measurement range of the meter.
TARGETING
The IR5 features dual lasers
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.
The meter is configured with 12:1 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
function of the distance between the meter and the target area are
depicted below for 12:1 optical systems (Fig. 1).
