SWR/POWER METER USER MANUAL
Model : RS-101, RS-102, RS-402, RS-502
INTRODUCTION:
This SWR & POWER meter is a highly accurate RF meter for measuring Forward Power,
Reversed Power, & VSWR.
Main Features:
1. Large meter display for ease of reading.
2. Forward RF power readings (switchable to indicate either average power or Peak Envelope Power [PEP],
for SSB and AM transmitters),
3. Reversed RF power readings.
4. VSWR rations.
5. Illuminated meter.
6. Convenient control layout for ease operation.

<INSTALLATION>
<FORWARD POWER MEASUREMENT>
Transmitter SWR Meter 1. Set the FUNCTION Switch to " FWD"
2. Set the radio transceiver to transmit mode and read the scale
corresponding to the Power RANGE selected.
3. When the AVG/PEP button is 'out', the meter reads average RF power.
When the button is 'pressed', the meter reads Peak Envelope Power
for use with SSB and AM transmissions. In this mode, there will be a
DC power supply slow rise and decay time.
<OPERATION>
Transmitter Forward <REVERSE POWER MEASUREMENT>
This measure the reverse power on the coaxial cable between transceiver
and antenna. The rest the settings are the same as that of
< FORWARD POWER MEASUREMENT>
SWR Meter
Transmitter Reversed <VSWR MEASUREMENT>
1. Set the radio transceiver to transmit mode and Function Switch to "CAL"
2. Slowly turn the CAL. Control knob clockwise until the meter pointer is at
meter full scale.
3. Now set the Function Switch to "SWR" position whilst still transmitting,
the meter will indicate VSWR ratio.

[CAUTION]
1.Since the meter movement is very sensitive, avoid excessive vibration or
mechanical shock to the meter.
2. Watch the absolute maximum power could be applied to the meter by
different models you bought.
3.The meter must never be reverse connected. Always observe the correct
connections to transmitter and antenna as indicated on the rear sockets.
4.Do not expose the meter to excessive temperatures, high humidity, or
strong magnetic fields.
