Introduction
Congratulations on your purchase of the Model 42529 IR Thermometer. This thermometer makes
non-contact (infrared) temperature measurements at the touch of a button. The built-in laser pointer
increases target accuracy while the backlit LCD and handy push-buttons combine for convenient,
ergonomic operation. Proper use and care of this meter will provide years of reliable service.
Safety
ï‚· Use extreme caution when the laser pointer beam is on
ï‚· Do not point the beam toward anyone's eye or allow the beam to
strike the eye from a reflective surface
ï‚· Do not use the laser near explosive gases or in other potentially
explosive areas

Operating Instructions
1. Hold the meter by its Handle Grip and point it toward the device whose temperature is to be
measured.
2. Press and hold the red Trigger to turn the meter on and begin testing. The display will light if the
battery is charged. Replace the battery if the display does not light.
3. While continuing to press the Trigger, push the red Laser button to turn on the laser pointer.
Aim the red beam approximately a half inch higher than the point of test as shown in the
diagram below (pressing the Laser button again turns the laser off).
4. While measuring, the SCAN display icon will appear on the LCD above the temperature
measurement and to the left of the emissivity value (fixed at 0.95.).
5. If the measurement exceeds the useable temperature range (0 to 600
oF), the meter will emit a
tone and the LCD will display ‘OVER’.
6. Release the Trigger when the temperature stabilizes. The HOLD display icon will appear on the
LCD indicating that the reading is being held.
7. Set the temperature units (
oC or oF) using the blue oC and oF buttons.
8. Press the yellow Backlight key to turn on the LCD backlighting function.
9. The meter will automatically power down after 7 seconds.
Field of View
The meter’s field of view is 6:1. For example, if the meter is 30.4cm from the target (spot), the
diameter of the target must be at least 5.08cm. Other distances are shown below in the field of view
diagram.
Note that measurements should normally be made less than 60.9cm from the target. The meter can
measure from further distances but the measurement may be affected by external sources of light.
In addition, the spot size may be so large that it encompasses surface areas not intended to be
measured.
Measurement Notes
1. The object under test should be larger than the spot (target) size calculated by the field of view
diagram (see diagram on previous page or on side of the meter).
2. If the surface of the object under test is covered with frost, oil, grime, etc., clean before taking
measurements.
3. If an object's surface is highly reflective apply masking tape or flat black paint before measuring.
4. The meter cannot measure through transparent surfaces such as glass.
5. Steam, dust, smoke, etc. can obscure accurate measurements.
6. The meter compensates for deviations in ambient temperature. It can, however, take up to 30
minutes for the meter to adjust to extremely wide ambient temperature changes.
7. To find a hot spot, aim the meter outside the area of interest then scan across (in an up and
down motion) until the hot spot is located.
