S-40 SWR or Power Meter

Product Information

Product Name: SWR/POWER Meter

Model: RS-40

Main Features:

• Direct reading without calibration
• Maximum measurable power range up to 200W
• Low insertion loss structure for permanent connection

Product Usage Instructions

1. Output Power Measurement

1. Set the function switch to the “PWR” position
2. Set the power range switch to the appropriate power range
   corresponding to your radio equipment (High: 200W, Medium: 60W,
   Low: 15W)
3. Put your radio equipment on transmit mode and read the scale
   corresponding to the selected power range

2. SWR Measurement

1. Measure the output power as described in the section 1
2. Keep the power range switch unchanged and set the function
   switch to the “SWR” position
3. Put your radio equipment on transmit mode and find the SWR by
   reading the cross-section of the extension point of auxiliary scale
   at the right end, which corresponds to the power reading indicated
   in section 1 and the meter indicator reading (High range…, Medium
   range…, Low range…)

Specifications

Notes:

1. Avoid excessive vibration or mechanical shock as the meter
   movement is very sensitive.
2. The maximum power that should be applied to the meter is 200W.
   Also, observe maximum power inputs of 15W and 60W when using the
   two lower ranges.
3. Never reverse connect the meter. Always observe the correct
   connections to the transmitter and antenna as indicated on the rear
   sockets.
4. The meter has been carefully calibrated at the factory.
   Tampering with any of the internal circuitry or sensors may cause
   damage and degrade the meter’s accuracy.
5. Avoid exposing the meter to excessive temperatures, high
   humidity, or strong magnetic fields.

SWR/POWER METER USER MANUAL

Model: RS-40
Main features : RS-40 SWR&POWER meter can read out directly without any calibration. RS-40’s maximum measurable power range up to 200W.
Low insertion loss structure allows it to be connected permanently.

1. Output power measurement (1) Set the function switch to PWR position (2) Set the power range switch to appropriate power range corresponding to the power of your radio equipment (3) Set the radio equipment on transmit and read out a scale corresponding to the range. (High:200W, Mideum:60W, Low:15W)

2. SWR measurement (1) Measure output power as described in the section 1. (2) Power range switch remain unchanged, set the function switch to SWR position. (3) Set the radio equipment on transmit mode, and figure out SWR by reading out cross section of the extension point of auxiliaryscale at the right end which is corresponding to the power reading indicated in section 1 and meter indicator reading. (High range…, Medium range…, Low range….)

Note:

1.Since the meter movement is very sensitive, avoid excessive vibration or mechanical shock . 2.The absolute maximum power that should be applied to the meter is 200W.
Also observe maximum power inputs of 15W and 60W when using the two lower ranges. 3.The meter must never be reverse connected. Always observe the correct connections to
transmitter and antenna as indicated on the rear sockets. 4.The meter has been carefully calibrated at the factory, Tampering with any of the internal
circuitry or sensors may cause damage and will degrade the meter’s accuracy. 5.Do not expose the meter to excessive temperatures, high humidity, or strong magnetic fields.
