8. To confirm your choice press the appropriate frequency unit.
9. Connect the power sensor to the signal to be measured.
10. The measurement result is now displayed.
Note If the measurement frequency does not correspond directly to a
frequency in the sensor calibration table, the power meter
calculates the calibration factor using linear interpolation.
If you enter a frequency outside the frequency range defined in the
sensor calibration table, the power meter uses the highest or
lowest frequency point in the sensor calibration table to set the
calibration factor.
The value of the calibration factor being used by the power meter
to make a measurement is displayed under the
softkey.
