Parameters
<rang> = Range parameter for the specified function. For example for
DCV, range parameter value 10 selects the 10V range. See the
“NOTES” that follow
Table 13-1 for additional information.
<res> = 0.1 i.e., 100.0 V (3 digits)
0.01 i.e., 10.00 V (3 digits)
0.001 i.e., 1.000 V (3 digits)
0.0001 i.e., 1.0000 V (4 digits)
0.00001 i.e., 1.00000 V (5 digits)
0.000001 i.e., 1.000000 V (6 digits)
The resolution of the <res> parameter value and the selected
range sets the number of display digits. As shown above, with
the 100V range selected and <res> = 0.1, a 100V reading will
be displayed as 100.0 V (3 digits).
The display will default to 3 digits when using parameter
values that attempt to set the display below 3½ digits. For
example, a 10V reading using <res> = 0.1 for the 10V range is
displayed as 10.00 V, not 10.0 V.
A command using parameter values that attempt to set the
display above 7 digits is ignored and generates error -221
(settings conflict error).
See the “NOTES” that follow Table 13-1 for additional
information.
<clist> = Single channel only. When included, this is the channel to be
closed and measured.
