The sensitivity control is not just for the SWR readout. It also adjusts the Relative Power function of the meter. That is the function that I use most along with monitoring the plate current and HV.

"Relative" is the key word. The sensitivity control position is a don't care" as long as the meter pointer is not reading full scale all the time. But the meter reading itself is meaningless. Get a good accurate SWR or power meter that you can hang between the amplifier and the antenna.
