Got line EMI noise reading, now what?

Just picked up a Trifield line EMI monitor and got these readings:

95.2 mVp-p (bottom)
221.1 mVp-p (peak)

The numbers jump up and down non-stop. Is this normal?

The manual says <50 mVp-p is what I need to shoot for for low noise application. What am I supposed to do now? I can hear hum when I get close to the speakers near my equipment rack. Time to pick up a PS Audio Powerplant? I doubt a run of the mill electrician will able to "fix" this line issue as long as I get normal AC power from the outlet.

Thanks.
