To minimize any overshoot, adjust the TS850 as follows:  Set the CAR control to 
give you about 1/4 scale deflection on the ALC scale.  Then set the PWR control 
to give you the desired power output to drive your amp.  Finally, back off the 
CAR control until the power output just begins to drop off (or a little before 
this).  When tuning the amp, use the PWR control on the 850 as needed.

A scope would tell you whether there was overshoot.  I'm not familiar with the 
Centurion, but I am very suspicious of any RF sensing arrangements.
