Diamond SX-600 User manual

INSTALLATION
To install the SX-200/400 or SX-600/1000 simply connect coaxial cable directed to the antenna connector marked "ANT",and
The cable coming from the transmitter or from the linear amplifier to the connector marked "TX"
SX-200/400 or SX-600/1000 is ready to operate.
POWER MEASUREMENTS
I Select the RANGE (3) switch on the end-scale position value as to the power of the unit
2 Select the FUNCTION (4) switch in the power position
3 Select the POWER switch the FWD position to measure the direct power(from the radio to antenna)
or REF position to measure the reflected power(from antenna to the radio)
4 Select the power value can be read on the corresponding scale.
SWR MEASUREMENTS
I Select the RANGE (3) switch on the end-scale position value as to the power of the unit.
2 Select the FUNCTION (4) switch in the CAL position .
3 Let the radio transmit and adjust the instrument by turning the CAL knob, position the end-scale index in the
CAL position.
4 Select the FUNCTION (4) switch in the SWR position
5 Read the SWR value in the above scale.

INSTRUCTION
THE SX-200/400 and SX-600 or SX-1000 POWER&SWR meter is the most efficient tool in wide range of semi-professional
MeasuringAnd control instruments. the measured values can be easily read in the large scale instruments.
The SX-200/400 and SX-600 or SX-I000 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 l3.8DC power which permits to light up the Meter and shows
the active led corresponding to the selected RF coaxial line ( for SX-600 and SX-I000)
