OPERATING INSTRUCTIONS

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 . Typical diameters of the measurement area as a
7
function of the distance between the meter and the target area are
depicted below for 12:1 optical systems (Fig. 1).

MODE SELECTIONS
When measuring temperature the meter continuously samples the
object being measured. Following a measurement, repeatedly press
the mode control button
• the maximum temperature value measured ("MAX").
• the average value measured ("AVG").
• the difference between maximum and minimum values
measured ("DIFF").
• the minimum value measured ("MIN").
• press once more to exit the MODE menu.
SETTINGS
User adjustable settings may be defined using the SET control button
Press SET to enter the settings menu, subsequent presses of SET cycle

through the following list of options:
• emissivity: set the numerical value of the emissivity to match
the surface being measured (see EMISSIVITY section below).
When in this setting the emissivity icon will flash on the display.
• units: Switch between °F (Fahrenheit) and °C (Celsius). When
in this setting the "°F" or "°C" icon will flash on the display,
indicating the temperature scale that is currently active.

• mute temperature limit alarms: (turn audible limit alarms on/

off). When in this setting the audible icon " "will flash on the
display. When on, the high "

• high temperature limit setting: assign a numerical value to the
high temperature limit. When in this setting, the high icon "
will flash on the display.
• low temperature limit setting: assign a numerical value to the
low temperature limit. When in this setting, the low icon "
will flash on the display.
When in any setting, control buttons
to adjust settings and they may be used to select units, turn alarms
on or off, or adjust the numerical values of the respective parameters
up or down.
