how to calibrate my AD converter

I think I'm ready to tackle this. My Lavry Blue AD is factory calibrated at -20, but I want to calibrate to something like -16. I have a Great River MP2NV and PTLe (Digi001), which can produce a 1Khz tone. How would I go about calibrating the AD converter with this setup. I know how trim the Lavry, I just want a step by step procedure on how to go from the tone generator to the AD converter. Will I need an outboard tone generator or is the PTLe good enough?
