WARNINGS

To ensure safe operation and service of the tester, follow these
instructions. Failure to observe these warnings can result in severe
injury or death. Retain these instructions for future reference.

WARNING: LASER RADIATION. DO NOT STARE INTO BEAM.
Class II Laser.

• Exposing eyes to laser radiation can result in severe and permanent
eye injuries. NEVER look directly into the laser beam emitted by this
instrument.

• DO NOT use the instrument if the case is damaged in any way.

• DO NOT modify the instrument in any way, as to do so could result in
emission of hazardous laser radiation than could result in severe and
permanent eye injuries.

• DO NOT use optical equipment such as lenses, prisms, optical scopes,
etc. to transmit, retransmit, or view the laser beam as this could result in
severe and permanent eye injuries.

• This product should not be used in any location that could result in
somebody looking at or having their eyes inadvertently irradiated by the
laser beam as this could result in severe and permanent eye injuries.

• This product should not be used by untrained operators or operators who
have not read and fully understood the instructions.

• Thermometer is NOT intended for use on people or animals.

• DO NOT remove warning labels from this instrument as this could result
in serious personal injury and increases the risk of exposure to hazardous
laser irradiation.

• Discontinue using the instrument immediately if it is acting abnormally.

• Be cautious of infrared temperature measurements of reflective materials
as the instrument may indicate that these surfaces are cooler than their
actual temperature (see Emissivity section).

• There are no user serviceable parts in this instrument.

SAFE PRACTICES

This meter is designed for professionals who understand the hazards
associated with their trade. While this meter causes no foreseeable
dangers beyond its targeting laser, the objects being measured, as
well as the environment in which they reside, can be hazardous.
Common safety practices to follow when operating near temperature
critical environments are:

• Before using this meter, determine if an area is safe, verify correct operation
by measuring a known temperature value of a comparable object.

TEMPERATURE MEASUREMENT

To measure temperature with the IR1, aim the meter at the object to
be measured, pull the trigger

and hold it depressed for at least 2

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 IR1 features a laser

to assist in targeting the measurement

5

area. Measurement areas located far away from the meter will be
larger than those close to the meter.

The meter is configured with 10:1 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 10:1 optical systems (FIG. 1).

MAINTENANCE

BATTERY REPLACEMENT

When indicator is displayed on LCD, battery must be replaced.

1. Loosen the screw in the Battery Compartment Door 3 to open.

2. Remove exhausted 9V battery and dispose of appropriately.

3. Replace 9V battery and return Battery Compartment Door

and tighten screw to secure, taking care not to over-tighten.

CLEANING

Be sure meter is turned off and wipe with a clean, dry lint-free
cloth.

Do not use abrasive cleaners or solvents.

Take care
to keep the sensor lens clean at all times. If required, loose
debris may be removed from lens using clean compressed air.
Lens may also be cleaned using a soft cloth or cotton swab
with water or rubbing alcohol

only

. Lens must be allowed to

completely dry prior to use.

STORAGE

Remove the battery when meter is not in use for a prolonged
period of time. Do not expose to high temperatures or
humidity. After a period of storage in extreme conditions
exceeding the limits mentioned in the General Specifications
section, allow the meter to return to normal operating
conditions before using.
