2.Making a measurement

The object being measured should be a minimum of twice the size of the infrared thermometer’s lens. The ideal measuring distance is 3 to 12 inches, which will yield a measurement area of ½ inch to 2 inches. As the infrared thermometer is moved away from the object being measured the area being measured increases (6:1 ratio).

The infrared thermometer is switched on by holding the operating button down for 1.5 seconds or more. By continuously holding down the operating button the measured value will be updated as long as the operating button is pressed. Releasing the operating button will finish the measurement. The “Hold” indication signals that measuring has stopped. The backlight will shut off 4 seconds after the operating button is released. The infrared thermometer will automatically switch off 8 seconds after the last measurement. Holding down the operating button again will clear the minimum and maximum memory and begin a new measurement.

3.Minimum and maximum temperature indication

The minimum and maximum value memories are cleared at the start of a measurement by pressing the operating button. The temperature will be measured and the minimum and maximum temperatures will be determined for as long as the button is pressed. The minimum temperature is shown in the lower left-hand part of the display and the maximum temperature can be seen in the lower right hand part. These values each apply to the current measuring cycle and are cleared as soon as the button is pressed again.

4.Changing the temperature units ( °F/°C )

The units for the temperature display can be switched between degrees Celsius (°C) and degrees Fahrenheit (°F) by pressing the button briefly twice (double click).
