If you mean radar level 'configuration' (as opposed to calibration) which establishes the LRV and URV for 4-20mA for a specific type medium and tank material, and might require a scan of the tank geometry to eliminate false echoes, those task are described in the device user manual.
If you mean "calibrate" meaning a check against a known certified standard, then have a tape measure certified, configure the radar for distance in the same units as your tape measure, shoot the radar at a metal target at several tape-measured known distances and determine the the error (difference) between the displayed distance value and the tape-measured value.
Someone else has to comment on a Cameron Scanner 2000 whatever that is.
