4.1.3. Tester calibration
To ensure the SWR measurements are accurate, it is necessary to calibrate the tester.
Following the instructions on the screen, just disconnect your antenna from the RP-
SMA connector; the calibration will then be done automatically.
In general, it is sufficient to perform calibration only once, after the tester is turned
on for the first time. However, it is recommended to re-calibrate the device if ambient
conditions, such as temperature, are significantly changed.
