Connect the transmitter to the unit and the antenna to the connector using quality coax.

The internal lamp requires 12 VDC to illuminate the meter scale.
Connect a 50-ohm dummy load to the ANTENNA connector to measure power output.
Push the ON/OFF button to turn the unit ON; 12 VDC also activates the lamp.
Use the 300/30 Watt button to select 300/60 Watts or 30/6 Watts scales.
Use the PEAK/AVG button to switch between peak envelope and average power readings.
Interpret the forward power measurement on the left meter scale based on the selected range.
