The monitor output voltage is 1.414 V (1 Vrms) when the voltage level is same as the level in the full scale of the level range. Also, the analog filters of A-weight, B-weight and C-weight which are selected in the filter setting (Input > Voltage range setting > Filter setting) are applied.

For example;

The voltage range display can be selected by Vrms (Effective value), dBVrms (Logarithm) or V (Half amplitude). Above is the calculation formula when the setting is Vrms (Effective value). If you want to display the value in dBVrms (Logarithm) or V (Half amplitude), change the setting to Vrms (Effective value).
