II. INTRODUCTION Combines Infrared, RTD and thermocouple capabili-
ties in a single unit. For general purpose applications chose any type
K, J, R, E, or T thermocouple probe. For a precise temperature read-
ing use the PT100 RTD probe. The built-in IR thermometer features a
laser guide and adjustable emissivity. The distance-to-spot ratio is ap-
proximately 7:1. Other features include RS232 computer interface, C &
F selection, min-max memory, relative temperature, auto power off and
hold. Has a convenient tripod back and an easy to read back-lit display
with large ½" high digits.
LASER WARNING!
III. OPERATING INSTRUCTIONS - See Fig A, page 2 for button locations.
A. IR MEASUREMENT
1. Press the POWER button (2) to turn the unit on. The display will count
down from 99999, 88888, etc. to 00000, then show the IR temperature
and the emissivity on the LCD's right bottom corner.
Example indicates a temperature of
74°F with emissivity of 0.95
2. Use the °C/°F button (7) to change scales.
3. Point the IR Sensing Head (12) at the object to be measured.
The meter will display the surface temperature.
EMISSIVITY - All objects emit invisible energy. The amount of energy is
emitted proportional to the object's temperature and it's ability to emit
energy. Emissivity is based on the material that the object is made of and
it's surface roughness. Emissivity values range from 0. 1 for highly
reflective objects, to 1.00 for a flat black surface. The probe of your IR
Thermometer senses energy and calculates the temperature based on the
amount of IR energy it receives, plus a factory set emissivity value of 0.95.
An emissivity value of 0.95 will cover 90% of the typical applications. If the
emissivity value of the measured material is not 0.95, you can adjust the
emissivity value. Matching the correct emissivity with the specific value of
the object is important in order to obtain the exact temperature.
Press the EMISSIVITY button (8) for at least 2 seconds. Release the but-
ton when the emissivity value begins to flash. Use the Õleft button (2) to
select the digit and the
× up (7) or Ø down (4) buttons to adjust the emissiv-

CAUTION: Do not point laser directly at eye.
Use caution around reflective surfaces. Keep
out of reach of children.
