VECTRONICS PM-30
SWR/Power Meter
INTRODUCTION
The PM-30 can simultaneously measure and display forward power,
reflected power, and SWR in the frequency range of 1.8 to 60 MHz.
Accuracy of the readings is assured because the PM-30 features a
true shielded directional coupler. The back lit meter can also display
either peak or average power readings.

- Page 3 2. The Peak Reading feature may be switch on/off by using the pushbutton switch labeled POWER PEAK/AVG. Peak reading is activated when the switch is locked in. 3. SWR is indicated at the intersection of the two meter pointers. While transmitting, read the SWR from the red SWR line nearest the intersecting point.
