4. Emissivity: Most organic materials and painted or oxidized surfaces have an emissivity of 0.95 (pre-set in the unit). Inaccurate readings will result from

measuring shiny or polished metal surface. To compensate, cover the surface to be measured with masking tape or flat black paint. Measure the tape or painted surface when the tape or painted surface reach the same temperature as the material underneath.

Release the trigger and the reading will hold for 7 second.LCD display: A data hold icon B scanning icon C laser on icon D back light on icon E battery power icon F measuring unit G measuring reading 2. Locating a hot spot: To find a hot spot aim the thermometer outside the area of interest, then scan across with up and down motions until you locate the hot spot.(please turn on the laser for accurate measuring)

and push the button, read current surface temperature in less than a second. Safely measure surface temperature of hot,

hazardous or hard-to-reach objects without contact.

Warning Do not point laser directly at eye or in-directly off reflective surface.

1. When taking measurement, points thermometer toward the object to be

measured and hold the yellow trigger. the How it works object under measuring should be larger Infrared thermometer measure the surface than the spot size calculated by the field temperature of an object. The units optical of view diagram.

1) Lens cleaning: Blow off lose particles using clean compressed air. Gentlydetection hole brush remaining debris away with a moist cotton cloth.

2) Case cleaning: Clean the case with a damp sponge/cloth .
