Pop one leg of the resistors associated with the S meter voltage divider and measure them with a dmm.
If they are out of spec you should replace them. Also, you may want to go with higher wattage resistors if
you notice that the S meter drifts after power-on. I have completely forgotten if the 102 has a S meter zero pot or not.
Oh yeah, if all else fails, read the manual!
