    4. MEASURING PROCEDURE 1)One hand hold the " Handle " ( 3-10, Fig. 1 ), use finger to press the " Operation Switch " ( 3-9, Fig. 1 ) continuously. 2)Point the " IR Sensing Head " ( 3-8, Fig. 1 ) to the measuring object until meter show the stable temperature values ( approx.

  • Page 9: Measuring Consideration

    5. MEASURING CONSIDERATION 5-1 Emissivity * All objects emit invisible energy. The amount of energy is emitted in proportion to the object's temperature & its ability to emit energy. This ability is so-called emissivity which is based upon the material that object is made of and its surface roughness.

  • Page 10: Disturbance

    5-3 Disturbance Fig. 2 Under certain measurement case, if the object is adversely effected by powerful infrared energy radiated from nearby objects having high emissivity or high temperature. For example, when such objects are measured in sunlight, erratic measurements can result due to powerful radiated energy from the sun reflecting on the surface of the object and entering the sensor.

  • Page 11: Emissivity Adjustment

    5-4 Emissivity Adjustment * The emissivity value set by the factory is 0.95 which will cover 90% of most measurement applications. However, select the correct emissivity value in order to obtain the true temperature is important. * When the emissivity of the object is known and its value is not 0.95, it is recommended to adjust the emissivity value to obtain the best accuracy.

  • Page 12: Special Surfaces

    5-5 Special Surfaces If the meter seems to be giving incorrect readings, then the emissivity value for the object may be incorrect. It may be necessary to change the emissivity value. See procedures on page 9. ( refer to 5-4 ). If the surface to be measured is covered by frost or other material, clean it to expose the surface.

    6. BATTERY REPLACEMENT Battery condition indicator Low battery indicator 1)When the LCD display show the " Low battery indicator " as above, it is necessary to replace the battery. However, in-spec measurement may still be made for several hours after low battery indicator appears before the instrument become inaccurate.
