TEMPERATURE MEASUREMENT

To measure temperature with the IR5E, aim the meter at the object
to be measured, pull the trigger
two 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 IR5E 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).
