Model 2750 Multimeter/Switch System User’s Manual Range, Digits, Rate, Bandwidth, and Filter 4-7
Setting digits
Even though the parameters for the DIGits command are expressed as integers (4 to 7),
you can specify resolution using a real number. For example, to select 3H digit resolution,
let <n> = 3.5. Internally the instrument rounds the entered parameter value to the nearest
integer.
As implied by the commands in Table 4-3, each mainframe input function can have its
own unique digits setting.
Digits programming examples
Example #1 — The following commands set digits for DCV and ACI:
VOLT:DIG 5.5 ' Set DCV to 5H digits.
CURR:AC:DIG 4 ' Set ACI to 3H digits.
Example #2 — The following command sequence configures channels 101 through 110
of the Model 7700 to select 4H digits when they are scanned.
FUNC 'RES' (@101:110) ' Select Ω2 function.
RES:DIG 4.5,(@101:110) ' Set scan channels to 4H digits.
