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.

Softkeys

Three softkeys on the HUM screen provide the following options:
