OPERATING INSTRUCTIONS

TEMPERATURE MEASUREMENT

To measure temperature with the IR5, aim the meter at the object to

be measured, pull the trigger

and hold it depressed for at least 2

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

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.

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

. Typical diameters of the measurement area as a

function of the distance between the meter and the target area are

depicted below for 12:1 optical systems (Fig. 1).
