- Page 2 The measurement range is +20 to -60dBm in 0.1dB increments. The AVM is a storage meter that stores and displays the highest RMS level received during the test interval so live program audio can be measured just as easily as test tones. It also simultaneously displays the instantaneous RMS level on a bar graph for audio status monitoring.
- Page 3 One way to do this is to measure the audio levels you cannot adjust with the AVM connected to the audio output of your TV monitor or cable set-top box. Average the readings taken on the non-controlled channels, and then use that dBm level as a reference to set the remainder of the channels.
- Page 4 The AMM is equipped with a 9 volt alkaline battery. When the battery runs down a message will appear in on the LDC window indicating “CHANGE BATTERY”. When the battery terminal voltage is below 3 Volts the AVM will not turn on. This prevents incorrect readings due to low battery voltage.
