Display fifth harmonic distortion, risen the amount of dB defined in the Setting Dialog.
Display total harmonic distortion, risen the amount of dB defined in the Setting Dialog.
Set output level equalize mode; after a sinusoidal measurement has been taken it
is possible to refer to the acquired frequency response in order to generate a colored
output that flattens out the subsequent response. For example if the following
pressure response has been measured
It is possible to obtain flat output from the same loudspeaker simply pressing the
equalize button

input channel
Selects the input channel configuration. See 5.6 for details.
Y Scale units
Selects the measurement Y scale unit. Possible choices are dBV, dBu, dBRel as
Voltage units, dBSPL as pressure unit, Ohm as impedance unit. dBV and dBu refer
the 0 dB on the scale to 1 V and 0.775 V, respectively. dBrel refers to the 0 dB on
the scale to the value set within the MULTI-METER. dBSPL switches the system to
work in pressure mode. A conversion from Volts to Pressure is accomplished, based
on the Microphone sensitivity set in the dedicated Dialog . Once the measurement
is taken the conversion is done and all the internal data is stored in Pressure. This
means that further changes to Microphone sensitivity does not affect any data in
