You either should replace the -6010 old style A7 or if building one from
scratch build the late style.
The new style has a BP filter on the 2nd harmonic that makes the 2nd
harmonic reading a better indication.
On the old style as you adjust the CF (in open loop) you will see the 2nd
harmonic reading rise! This is bogus and caused by the 137 Hz signal
bleeding through. On the new style when you move off frequency the 2nd
harmonic reading drops as it should!
