Calibration problems

[JEJ]

I need some help calibrating REW. There are several calibration windows. I have tried calibrating but it fails. I have a known voltage (292 mV) for a 1 kHz sine wave that I can input to the sound card and REW. Where do I set it to say 292 mV and then click Calibrate? I want it to read 292 mV in the RTA window. I have had this difficulty for months.

It's on the RTA, the "Calibrate Level" button above the graph, which is enabled when the RTA is running. The help for it is here.
