5.1. Surface Temperature Measurement
The temperature sensor measures the average temperature in a circle
of diameter one-eighth of the distance between the surface and the
sensor. For example, when the meter is held 1m from a surface, the
sensor will respond to a 125mm spot diameter on the surface. Thus, the
measuring distance will define the size surface to be measured. The
maximum recommended distance from surface to sensor is 2m and
hence the maximum spot diameter is 250mm. The measurement is
made as follows:-
Switch on the meter using the
SEL key
Press the
F/°C for the temperature mode
Aim the laser beam at the surface to be measured at a suitable distance
from the surface, remembering that the temperature sensor spot
diameter is one-eighth of the distance (ie not the laser spot size).
The temperature reading can be toggled between °F and °C using the
SEL key. Ambient temperature is indicated at the bottom left of the
display.
Exit the temperature mode by pressing the
Vib or Brg key .
