• With the compensation function activated, press <ENTER> to begin the measurements in order to calculate the
ambient temperature average value. Point OSP towards objects and surfaces surrounding the target, making a scan
over those items and acquiring corresponding temperature values. A counter (from 1 to 255) indicates the number of
measurements considered (OSP displays the first value read during this procedure). These acquisitions have to be
done with emissivity ε=1, hence when acquisition starts the emissivity value has set automatically to one.
• Press <ENTER> to stop acquisition and to confirm the read ambient temperature (at this moment OSP will display
the last acquired temperature value).
• Press the <SEL> key to select the new configuration step or press <Trigger> to switch the instrument off. The new
selections will be automatically memory stored.
To execute the temperature measurements with TAM, switch OSP on and set the emissivity to the correct target value.
