CALibration:CONFigure:VOLTage <range>,<zero_fs>
voltage reference to the Calibration Bus. A measurement of the source voltage can
be made with an external multimeter connected to the H Cal and L Cal terminals on
the Terminal Module or the V H, V L, Ω H, and Ω L terminals on the Cal Bus
connector when not using a terminal module. The <range> parameter controls the
voltage level available when the <zero_fs> parameter is set to FSCale (full scale).
Parameter Parameter
Name Type
range numeric (float32)
zero_fs discrete (string)
The <range> parameter must be within ±5% of one of the five following values:
•
0.0625 V dc, 0.25 V dc, 1 V dc, 4 V dc, 16 V dc. This parameter may be
specified in millivolts (mv).
•
The expected FSCALE output voltage of the calibration source will be
approximately 90% of the nominal value for each range, except the 16 V range
where the output is 10 V.
