- The SWR meter (reflectometer) often has two meters, one indicating forward power, the other reverse; when the forward meter is set by an adjusting knob to fsd the reverse meter calibrated in SWR may be read
- Alternatively a dual movement cross pointer meter may be calibrated so that the intersection of the needles gives SWR for any value of forward power
- As the meter contains diodes it should be placed before any low pass filter to suppress harmonics
