INSTRUCTIONS SWR/POWER METERS
SX-201, SX-400, SX-601, SX-1000
The SX-201/400 and SX-601 or SX-1000 POWER & SWR meter is the most efficient tool in wide range of semi-professional
measuring and control instruments. Measured values can be easily read in the large scale instruments.
The SX-201/400 and SX-601 or SX-1000 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 allows to light up the meter and shows
the active led corresponding to the selected RF coaxial line (for SX-601 and SX-1000)
