1.Quick Instructions

Press and hold the operating button for more than 1.5 seconds. The temperature of the surface the lens is aimed at will read on the top of the display. The minimum and maximum temperatures of the current measurement are shown on the bottom of the display. When the operating button is released “Hold” will be displayed between “min” and “max” indicating the measurement is completed. After 4 seconds the backlight will turn off. The unit will switch off after 8 seconds. Press and hold the operating button again to begin a new measurement. To switch between °F and °C simply “double click” the operating button.

2.Equipment Supplied

a.Infrared Thermometer base unit

b.4 button cell batteries (already in unit)

c.Neck strap

d.Soft sided case

3.Description of measuring principle

When making a temperature measurement, the surface radiation of the object to be measured is evaluated using the principle of radiation thermometry. This is a purely passive process, i.e. no radiation is transmitted, but instead, use is only made of the natural electromagnetic radiation energy (heat radiation) that every body above a temperature of absolute zero (-273 °C) has. The temperature can be determined very accurately from this radiation energy if the emission factor of the object being measured is known.

Operation

1.Display and operator controls
