HIH-4000 Humidity Sensor anyone?

I’m wondering if anybody is using HIH-4000 Humidity Sensor by Honeywell.
My sensor is connected to a WebControl PLC and I’m getting the readings in OH using http, no problem here.
My understanding that the values obtained from the sensors needs to be corrected/compensated using the calibration data supplied with the sensor. Here I’m lost a bit. Will be great to see a working example.
