5.1 Surface Temperature Measurement
The temperature sensor measures the average temperature in a circle of diameter
one-eight 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 the 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.
o
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-eight of the distance (i.e.
not the laser spot size).
C using the SEL key. Ambient
The temperature reading can be toggled between
F and
o
o
temperature is indicated at the bottom left of the display.
Exit the temperature mode by pressing the VIB or BRG key.
