Polynomials for UVS:

Polynomial in mV:

To have the output values recorded in mV (miliVolt) we will have to enter the following

polynomial

A1=1

If you are only interested in the UV values recorded by the instrument you would probably

like to have these reading in W/m².

Polynomial in W/m²:

To have the output values recorded in W/m² we will need to make some calculations using

the mean sensitivity values of the UVS instruments.

The mean sensitivity values can be located on the supplied calibration certificates.

Example:

The calibration certificate tells us that the mean sensitivity of the UVA = 30.083 W/m²/V and

the mean sensitivity of the UVB =1.879 W/m²/V.

In order to have the correct engineering units, W/m², we need to apply the following

equation:

A1=Mean sensitivity/1000

A1 (UVA)=30.083/1000=0.030083

A1 (UVB)=1.879/1000=0.001879

Now we can enter them inside the coefficient area:

The illustration above will result in the UVA and UVB readings to be in W/m² and the

temperature to be in V.

Please note that this cannot be used in combination with the Uviator application.

Uviator requires all outputs to be in Volt!
