Displays total harmonic distortion, risen the dB defined in the Settings Dialog.
Displays Fast-Track Rub&Buzz, risen the amount of dB defined in the Settings
Dialog. Note: Fast-Track Rub&Buzz is available only in QC software version.
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:
You obtain flat output from the same loudspeaker pressing the equalize button:

input channel
Selects the input channel (CHA or CHB). Choose CHA&B for a stereo
measurement when the two channels are measured and processed
simultaneously.
Y Scale units
Selects the measurement Y scale unit. Possible choices are dBV, dBu, dBRel as
Voltage, dBSPL, dBPa, dBPa/V as pressure, dBmeter as displacement, dBm/s as
velocity, dBm/s
2
as acceleration and 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. Refer to CLIO
Options>Units Conversion dialog for reference sensitivities. Once the
measurement is taken the conversion is done and all the internal data is stored
in the relative SI unit. This means that further changes global sensitivities do not
affect any data in memory or saved measurement. Ohm switches the system to
convert the measurements in Ohm basing the conversion on the Impedance
Mode Settings available in the Settings Dialog. When stereo measurements are
taken both channels share the same unit. Note: there is an important
exception to scale management; when a stereo measurement is taken
and the sinusoidal setting “Ohm Right Scale” is selected, then channel B
