INSTRUCTION
THE AV-201 and AV-601 POWER&SWR meter is the most efficient tool in wide range of semi-professional Measuring And
control instruments. the measured values can be easily read in the large scale instruments.
The AV-201 and AV-601 or is an insertion type RF wattmeter and can be permanently fitted into a transmission System for
continuous monitoring of station working condition .
The unit can be work without external power supply . but with 13.8DC power which permits to light up the Meter and shows
the active led corresponding to the selected RF coaxial line ( for AV-601 )
