OPEK SWR/POWER Meter SWR-6, SWR-7, SWR-8 User Manual
INTRODUCTION
This SWR&WATT meter is a highly accurate RF meter for measuring Forward Power, Reversed Power
,and VSWR by using cross-needle analog meter.
MAIN FEATURE
1. Large, precision, 2.5” (64mm) Cross Needlemeter display for ease of reading
2. Forward/Reversed/SWR readings display at the same time
3. True Directional Coupler for increased accuracy over frequency
4. Rugged metal cabinet with speckled black finish and designer style grey
injection molded front panel aesthetically complements modern transceivers

Antenna
1. Set the RANGE switch to the proper meter multiplier
(X1, X10, X100) for the expected power level of the
intended measurement.
2. It corresponds to 20/200/2KW forward and 5/50/500W
reversed in SWR-7, 2/20/200W forward and 0.5/5/50W
reversed in SWR-8 (Fwd : Rev = 4 : 1 in scale)
3. Set the radio transceiver to transmit mode and read the
scale corresponding to the RANGE selected
[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.
5. Contact your local dealer for service. Dealer information is in the back of user manual.
