Omega Engineering OSXL450 - Manual (Page 2)

Introduction
Compact rugged and easy to use. Just aim and push
the button, read current surface temperatures in less
than a second. Safety measure surface temperatures
of hot or hard to reach objects.
2) Locating a hot spot: Aim the thermometer outside
the area of interest. Scan across the area in an up
and down motion until the hot spot is located while
holding the activation trigger. The thermometer will
continue to read the surface temperature while the
activation trigger is depressed.
Instructions
1) Pull and hold trigger (laser pointer is on as default
setting) to turn on, LCD display reading & battery
icon. Release the trigger and the reading will hold
for approx. 15 sec.
Note
Holding the trigger at least one second when taking
recordings.
Operating
Fahrenheit & Celsius Conversion: Press the °F/°C
button to switch from Fahrenheit to Celsius readings.
Press the Laser ON/OFF button to turn the laser
pointer on or off.
The object being tested should be larger than the spot
size calculated by the field of view diagram printed in
this manual or on the unit itself.
Laser Pointer
To turn the laser pointer ON, press the LASER key
while pressing the Measure key. Repeat the procedure
to turn the laser OFF. While the laser is on, you can
switch between laser dot and circle by moving a lever
in front of the optics. Laser dot is an indication of the
center of the field of view. Laser circle is an indication
of the perimeter of the field of view
How it works
Any object radiates infrared energy if its temperature
is above absolute zero. This energy travels at the
speed of light in all directions. An infrared thermometer
lens collects and focuses the infrared energy into a
sensor. The sensor produces a small voltage output,
indexed to the target temperature, which is
processed and displayed.
Cautions
The infrared thermometer should be protected from
the following:
1. Electromagnetic Fields (created by arc welders
induction heaters and similar items.)
2. Thermal Shock (caused by large or abrupt ambient
temperature changes. Allow 30 minutes for unit to
stabliize before use.)
3. Do not leave the unit on or near objects of high
temperature.
