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.

INSTALLATION

1. Connect the coax connector labeled RF INPUT to the transmitter
using PL-259 connectors. If using an antenna tuner, the PM-30
should be placed between the transmitter and antenna tuner.

2. Connect the coax connector labeled RF OUTPUT to the antenna
using a PL-259 connector. If using an antenna tuner, the
RF OUTPUT is connected to the antenna tuner input.

: Vectronics recommends using high quality coax cable for all

Note

coax connections.

3. If a lighted meter is desired, a 9-12Vdc power supply, such as the
AC-12, must be connected to the power jack on the back of the unit.
This is a 2.5mm coaxial type jack with the center positive.

OPERATION

1. Set the desired power range by using the push-button switch on the
front panel labeled POWER 3000W/300W. With the switch in the
out position, the 300W range is selected. When the switch is locked
in, the 3000W range is selected.

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.
