After wiring the sensor cable and connecting it to WXT536, you can configure the analog input with Vaisala Configuration Tool.

To open the configuration window, select Settings > Analog inputs.

Set the following parameters:

• In Aux. level range, select 2.5 V.
• In Aux. level gain, type 4.208 and select OK.

The Aux. level gain is defined as follows:

$Aux\mathrm{.}levelgain=\frac{Max\mathrm{.}measurementrange-Min\mathrm{.}measurement}{Max\mathrm{.}voltageoutput}$
