RMS-PEAK Switch
The RMS-PEAK switch provides a means of scaling the meter circuit to read in
either PEAK or RMS units. When the input to the unit is sinusoidal, it may be
desirable to use peak g’s. When the input is random noise, the RMS position
scale the meter to read RMS units, and because the detector is a true RMS
converter, it will read either sinusoidal or random inputs correct in RMS units.
