value_in_unit
s = ((curve_in_dl - YOFf_in_dl) * YMUlt) + YZEro_in_units
NOTE. For a given w aveform record, YMUlt, YOFf, and YZEro have to be a
consistent set, otherwise vertical cursor readouts and vertical measurements may
give incorrect results.

Syntax
WFMInpre:YZEro <NR3>
WFMInpre:YZEro?
Related Commands
WFMInpre:YUNit, WFMOutpre:YZEro?
Arguments
<NR3> is the offset in YUNits.
Examples
WFMINPRE:YZERO 1.5E+0 specifies that the zero reference point for the
incoming waveform is 1.5 V below the center of the data range (given that
WFMInpre:YUNit is set to V).
WFMINPRE:YZERO? might return :WFMINPRE:YZEro 7.5000E-6 indicating
that the zero reference for the incoming waveform is 7.5 µV below the center of
the data range (given that WFMInpre:YUNit is set to V).
WFMOutpre? (Query Only)
Returns waveform transmission and formatting parameters for the waveform
specified by DATa :SOUrce command. If the waveform specified by the
DATa:SOUrce command is not displayed, the oscilloscope returns only the
waveform transmission parameters (BYT_Nr, BIT_Nr, ENCdg, BN_Fmt,
BYT_Or).
