<b> = 1 or ON Enable auto resolution
0 or OFF Disable auto resolution
ONCE Enable and then disable auto resolution
:AUTO? Query state of auto resolution
These commands are used to enable or disable auto resolution for the specified function. With
auto resolution selected, the instrument automatically selects the optimum resolution for the
present integration time setting (see Tables 2-10, 2-15, 2-20 and 2-25).
The ONCE parameter is analogous to a momentary toggle switch. When :AUTO ONCE is sent,
auto resolution turns on momentarily and then disables. While enabled, resolution is selected
automatically. Auto resolution then disables but the selected value is retained.
The auto resolution command (:DIGits:AUTO) is coupled to the command that manually selects
resolution (:DIGits <n>). When auto resolution is enabled, the parameter value for :DIGits
<n> changes to the automatically selected resolution value. Thus, when auto resolution is dis-
abled, the instrument remains at the automatically selected resolution.
PRINT #1, "output 16; :volt:dc:dig:auto on; auto?"
PRINT #1, "enter 16"
