9.3 Emissivity in case of an unknown value
To be used only outside the Ex-area!
Connect a sensor to set the device for a material having an unknown emissivity (only
outside the Ex-area). Then press the measurement button and maintain the measuring
range of the sensor within the range of the object to be measured.
Wait till the measured value of the sensor stabilises and then record the measured
value. Release the measurement button and press it again. Now measure the same
range of the object. Press the Emiss. key and select the „Free“ material name using
arrow keys. Press the Emiss. key again till the emissivity icon starts blinking. You can
now use arrow keys to change the value till the displayed temperature matches that of
the contact sensor.
For connecting the sensor, refer to 8.8.6.: Sensor port.
