SWR & Power Meter
This SWR & Power meter is a highly accurate RF meter for measuring Forward Power,Reflected Power, and VSWR.
· Large meter display for easy reading.
· Forward RF power readings, switchable to indicate either average power
· Reflected RF power readings.
· VSWR ratios.
· Convenient control for easy operation.
SURECOM SW-32 SWR & Power Meter Instruction
Explanation of Features:
1.Meter Display: Indicates Forward/Reflected Power in Watts and SWR ratio
2.Meter Zero adjust: Mechanical zero adjustment for meter needle
3.Range Switch: Selects RF Power Ranges of 10W and 100W
4.Blue Switch 1: Selects POWER , SWR
5.Red Switch 2: POWER of (REF/ FWD) , SWR of (set SWR / SWR)
6.SWR SET Control Knob: Sets full scale deflection when measuring VSWR.
7.ANT Connector : Coax connector to 50 Ohm antenna system.
8.TX Connector : Coax connector to transmitter 50 Ohm RF output.
FORWARD POWER MEASUREMENT
1. Set the Blue botton to the ‘POWER’ position. Set the Red botton ,‘FWD’ position.
2. Set the Radio transceiver to transmit and read the scale corresponding to the Power range selected yellow botton (10W, or 100W)
REFLECTED POWER MEASUREMENT
1. Set the Blue botton switch to the ‘POWER’ position. Set the Red botton ,‘REW’ position.
2. Set the radio transceiver to transmit and read the scale orresponding to the Power range selected (10W, or 100W)
1. Set the Blue botton switch to the ‘SWR set’ position.Set the Red switch to the ‘SET SWR’ position.
2. Set the radio transceiver to transmit mode.
3. Slowly turn the CAL Control Knob clockwise until the meter point is at the ‘ CAL ’ position. This should be full scale.
Set the Red botton switch to the ‘SWR’ position while transmitting. The meter will now indicate the SWR ratio.
1. Since the meter movement is very sensitive, avoid excessive vibration or mechanical shock to the unit.
2. The absolute maximumpower that should be applied to the meter is 100W. Also observe maximumpower inputs of 10W when unsing the lower ranges.
3. The transceiver and antenna connections to the meter must never be reversed.Always observe the correct connections
to the transmitter and the antenna as
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 accuracy of the meter.
5. Do not expose the meter to excessive temperatures, high humidity, or strong magnetic fields.
