User Manual InfraRed Thermometer with Laser Pointer MODEL IR400
Introduction Congratulations on your purchase of the Model IR400 IR Thermometer. The IR400 is capable of 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. This meter is shipped fully tested and calibrated and, with proper use, will provide years of reliable service.
Operating Instructions Basic IR Measurements 1. Hold the meter by its handle and point it toward the surface to be measured. 2. Pull and hold the trigger to turn the meter on and begin testing.

Field of View The meter’s field of view is 8:1. For example, if the meter is 8 inches from the target (spot), the diameter of the target must be at least 1 inch. Other distances are shown in the field of view diagram. Note that measurements should normally be made as close as possible to the device under test. The meter can measure from moderate distances but the measurement may be affected by external sources of light.
IR Measurement Notes 1. The object under test should be larger than the spot (target) size calculated by the field of view diagram (printed on the side of the meter and in this guide). 2. Before measuring, be sure to clean surfaces that are covered with frost, oil, grime, etc. 3. If an object's surface is highly reflective, apply masking tape or flat black paint to the surface before measuring. Allow time for the paint or tape to adjust to the temperature of the surface it is covering. 4.
