Query :DIGits? Query selected resolution
:DIGits? DEFault Query *RST default resolution
:DIGits? MINimum Query minimum allowable resolution
:DIGits? MAXimum Query maximum allowable resolution
Short-form formats: :curr:ac:dig? :curr[:dc]:dig?
:curr:ac:dig? xxx :curr[:dc]:dig? xxx
:volt:ac:dig? :volt[:dc]:dig?
:volt:ac:dig? xxx :volt[:dc]:dig? xxx
:res:dig? :fres:dig?
:res:dig? xxx :fres:dig? xxx
:freq:dig? :temp:dig?
:freq:dig? xxx :temp:dig? xxx
where; xxx = def, min or max
Description These commands are used to select display resolution for the specified measurement function.
Even though the parameters for this command are expressed as integers (4 to 8), you can specify
resolution using real numbers. For example, to select 3H digit resolution let <n> = 3.5, for 4Hd
let <n> = 4.5, and so on. Internally, the instrument rounds the entered parameter value to the
nearest integer. For example:
3.4 is rounded down to 3 (Illegal parameter)
3.5 is rounded up to 4
4.4 is rounded down to 4
4.5 is rounded up to 5
4.6 is rounded up to 5
Programming example10OUTPUT 716; “:curr:ac:dig 4.5; res?”
20 ENTER 716; A$
30 PRINT A$
40 END
Line 10 Sets ACI resolution to 4Hd, and then queries the selected resolution.
Line 20 Addresses the Model 2001 to talk.
Line 30 Displays the selected resolution (5).
