5.2 Cleaning:
5.2.1 Check and ensure that the equipment is clean and free from dust. If not, clean with a lint free cloth before use.
5.2.2 For the lens cleaning blow off loose particles using clean compressed air. Gently brush remaining debris away with a camel’s hair brush. Carefully wipe the surface with a moist cotton swab. The swab may be moistened with water. For case cleaning use soap and water on damp sponge or soft cloth. Do not submerge the unit in water.
5.3 Basic operation:
5.3.1 IR non-contact thermometer measured the surface temperature of an object. The unit optic sense emitted (E), reflected (R) and transmitted (T) energy, which is collected and focused on to a detector. The information displayed as temperature reading. To measure the temperature, point the unit at the object and pull the trigger.
5.3.2 Select the temperature °C/°F depending on the requirement.
5.3.3 °C/°F and Battery: Pull open the unit’s handle near the trigger to access the °C/°F switch or to insert or remove the battery.
5.3.4 Display: The backlight LCD displays the current temperature in Celsius or Fahrenheit. The unit will hold the reading for 7 seconds after trigger is released, the word hold appears. The presence of the battery icon indicates a low battery.
5.3.5 Locating a Hot spot: To find the hot spot aim the thermometer outside the area of interest, then scan across with an up and down motion until you locate the hot spot.
5.3.6 The minitemp thermometer is intended for close range targets measuring a minimum target area of 1 inch in diameter out to a distance of approximately 8 inch and has 3 inch target measuring area of 24 inch.
5.3.7 Field to view: Make sure that the target is larger than the unit’s spot size. The smaller the target, the closer you should be to it. When accuracy is critical, make sure the target is at least twice as large as the spot size.
5.3.8 Distance & Spot Size: As the distance from the object increases, the spot size of the area measured by the unit becomes larger.
5.3.9 The Non contact thermometer can access temperature range of -180C to +4000C (0 0F to 750 0F).
5.4 Calibration:
5.4.1 Carry out the calibration once in year by approved service contractors. Carry out the recalibration after major repairs.
