The Site Master can automatically set the scales to the minimum and maximum values of the measurement on the y-axis of the display. This function is particularly useful for mea- surements in SWR mode. To automatically set the scales:

Step 1. Press the AUTO SCALE key.

The Site Master will automatically set the top and bottom scales to the minimum and maximum values of the measurement on the y-axis of the display.

Amplitude Scale
