FM Mode: Meter Displayed Description
2.10.01 This meter displays the instantaneous modulation
packet showing the minimum and maximum level. It displays
a maximum of +/- 6 kHz deviation whether or not the
received signal is on frequency. Each division represents
1kHz; this display is showing +3 kHz/-4.2 kHz.
2.10.02 This reduces the scale to +/- 4 kHz. This allows more
resolution for detecting smaller signals without having to
zoom.
2.10.03 This meter is a numeric version of the above meters.

FM Mode: Meter Displayed Description
2.10.04 Displays a quickly updated percent of AM calibrated
demodulation. Every tick indicates 10%. This meter indicates
50% modulation, and the slow peak-hold point (larger
square) indicates a peak of 65% modulation.
2.10.05 Displays percent of demodulated AM. Accuracy is +/-
5%, but better than +/-1% using 1kHz tones.
