IE-45 Volt Meter
The IE‑45 Volt Meter displays AC Volts, dBu, dBV, and AC V peak to peak. Voltage measurement range (without external attenuator) is from very low microphone levels up to +24 dBu. You may define the Volt Meter scale by pressing either the "Zoom In" or "Zoom Out" button. You may toggle between different voltage measurements by pressing the measurement label directly above the green microphone label in the lower right hand window. While taking voltage measurements, you may also advance to the RTA screen in which you can see the entire spectrum while still measuring voltage in the lower right hand window.
