INSTRUCTION MANUAL
INTRODUCTION
This SWR & POWER meter is a highly accurate RF meter for measuring Forward/Reverse Power, and 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. Reverse RF power reading
4. VSWR ratio
5. Illuminated meter
6. Convenient control layout for ease operation

Fwd/Rev Power, PEP, SWR

<FRONT PANEL> <FRONT & REAR PANEL>
1. Meter Display : Indicates FWD/REV power in watts and VSWR ratio
2. Function Switch : Select FWD/REV power, SWR SET, and SWR
3. Range Switch : Selects RF power range of 5/20/200W, 30/300/3KW
4. SWR SET Knob : Sets full scale deflection when measuring VSWR
5. AVG/PEP knob (elliptical push button) : Selects Average or PEP RF
Power readings
<REAR PANEL> 6. Meter Zero Adj.: Mechanical adjustment for meter needle
7. TX Connector : Coax connector to transmitter 50 ohm RF output.
8. ANT Connector : Coax connector to 50 ohm antennna system.
9. 13.8V DC connection (via power supply) for meter LED illumination.
10. HF, VHF/UHF band switch : available on RS-502 only
11& 12. 2nd pair of TX/ANT connector : available on RS-502 only.
<FORWARD POWER MEASUREMENT>
1. Set the FUNCTION switch to FWD
<INSTALLATION> 2. Set the radio transceiver to transmit mode and read the scale
corresponding to the Power Range selected.
Transmitter SWR Meter 3. When the AVG/PEP button is 'out', the meter reads average RF power
When the button is 'depressed', the meter reads Peak Envelope Power
for use with SSB and AM transmissions. In this mode, there will be a
slow rise and decay time.
<REVERSE POWER MEASUREMENT>
DC power supply This measure the reverse power on the coaxial cable between transceiver
and antenna. The rest the settings are the same as that of
<OPERATION> < FORWARD POWER MEASUREMENT>
Transmitter Forward
<VSWR MEASUREMENT>
1. Set the radio transceiver to transmit mode and Function Switch to SWR SET
2. Slowly turn the SWR SET control knob clockwise until meter pointer is
at meter full scale
3. Set Function Switch to "SWR" position whilst still transmitting, the
meter will indicate VSWR ratio. (Note : handheld and mobile have H/L
range, when using 'H' range, read the upper SWR dial. Using 'L' range,
SWR Meter read the lower SWR dial)
[CAUTION]
Transmitter Reverse 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
