You can view Hum measurements by viewing each channel. Channel tuning
measures the hum level of a channel. Hum measurements are continuously
updated on the screen.
Channel Tuning
Hum measurements are displayed on a bar graph and as a numeric value for
each carrier within the channel. Use the alphanumeric keys to tune directly
to a specific channel and press ENTER to complete your entry.
The arrow keys provide an alternate method to tune your meter. Use the
up and down arrow keys to increment or decrement to the next or previous
channel as defined in the current channel plan. Use the left and right
arrow keys to adjust the marker on the graph.
