S meter calibration?

[KD7PY]

when calibrating the S meter, the manual says to have the pre-amp on, SMTR MD to Relative (NOR)
I find that I can't even get close.
with the pre-amp off it fall right into spec. as per the manual, with the SMTR MD set to Nor
I am using the XG2, and receiving on 20 mtrs.
with SMTR MD set to Abs and with the pre-amp on it falls right into spec..
am I missing something ? or is the manual in error..

The manual is correct, and has always worked for me.  In fact, I just ran
the calibration on four S-meters (two main K3 receivers and two KRX3s).  The
instructions also call for AGC-S ON and SMTR PK OFF with the XG2 signal in
the middle of your passband.

Well anyway this is how I like it...and i'll leave it alone
with pre amp off   50mv = s9
with pre amp on    50mv = 10/s9
