Explanations
:
:measure:voltage:DC:digit? queries the digit of the DC voltage.
:measure:voltage:DC:digit
□
{INC|DEC|5|6|7} set the digit of DC voltage.
Remarks:
If the showing digit reachs 5, DEC command will be invalid. If 7,INC
invalid.

:measure:voltage:DC:ratio
Syntax:
:measure:voltage:DC:ratio?
Function:
The command queries the ratio of DC voltages in two circuits.
Remark
:
At the same time the DC voltages in two circuits should be input in the multimeter.
Return Format:
The query returns the current ratio in the form of 4.656613e-05(for example).
