I made a raster. I wonder how can I remove pixels with values lesser than an specific value? for example How is possible to set the value of classes from 0.92?

i have searched it and i found this answer to Removing pixel values below 0 in Digital Elevation Model in ArcGIS for Desktop?:

You can use tool Raster Calculator. Then type this expression:

SetNull("raster_name"<0.92, "raster_name")

should i type the "SetNull" in the command? i am really confused....
