Attach the meter (with the receiver unplugged) inline between the LNBF and the satellite receiver. Plug in and turn on the satellite receiver, then turn the sensitivity knob up as high as you can untill the meter just starts to move up the scale. Then as you scan the sky and the dish points towards a satellite, the meter will rise in value. If the meter goes past the end of the sacle, then turn down your sensitivity. This will get you close to the satellite, then use your Quality meter on your television display to fine adjust your dish and skew of the LNBF for maximum quality. Remember, adjust for maximum Quality, not signal on your television display. You must have your satellite receiver set to an active channel for the quality meter to display any value.
