2. Frequency Selection – The carrier frequency is displayed at the top of
the LCD screen. A specific center frequency can be selected using
either of these two methods:

a) Using the numeric keypad type in the frequency to

be measured in units of MHz. Then press the
MHz button to enter this number into the meter.

b) Press the MHz button. Then use the   buttons

to change the carrier frequency in steps of 10 kHz.

When the meter is set to a frequency that is a carrier of an active stored channel,
then the channel number will also appear at the top of the LCD screen. If the
frequency corresponds to the video carrier, then the meter will display “CHV”
next to the channel number. If the frequency corresponds to the audio carrier,
then the meter will display “CHA” next to the channel number.
When the meter is set to a frequency that is not a carrier of a stored channel, the
meter will display “:???”

After the specific channel or carrier frequency is selected, the meter will measure
and provide the carrier power reading. The numerical result will appear in the
middle of the LCD screen. See figure 3.
