3.3 Setting the Emissivity/Non Greyness value
3.3.1 U series thermometers
In U series (i.e. single wavelength) thermometers, the emissivity value is set using
switches SW2 and SW3. Refer to Fig. 7.
The emissivity can be set in the range 0.10 to1.09 in steps of 0.01.
When switch SW2 is set from 1 to 9, this denotes the first figure
after the decimal point
of the emissivity value. e.g. for an emissivity value of '0.83', set SW2 to '8' and SW3 to'3'.
When switch SW2 is set to 0, this denotes a '1'
before, and a '0' after, the decimal point
of the emissivity value.
e.g. for an emissivity value of '1.00', set SW2 to '0' and SW3 to'0'.

NOTE
An emissivity value of above 1.00 is not common in the majority of
measurement applications.
