Function
：
The command queries DC voltage range.
Remark
：
Please make sure the DC voltage measure must be set at least one time before using
this command
Return Format
：
The query returns the current range parameter: 0,1,2,3 or 4(see Table 2- 1).

:measure:voltage:DC:impedance
Syntax
：
:measure:voltage:DC:impedance?
:measure:voltage:DC:impedance
□
{10M|10G}
Function
：
The command queries and sets DC voltage impedance.
Explanations
：：
:measure:voltage:DC:impedance? returns 10M or 10G(>10G).
:measure:voltage:DC:impedance
□
{10M|10G} sets the DC voltage impedance as
10MΩ or >10GΩ.
Remark
：
“>10G” is available only in 200mV
，
2V
，
20V of the DC voltage range.
Example
：
To set the DC voltage impedance as 10GΩ
：
:measure:voltage:DC:impedance
□
10G

:measure:voltage:DC:digit
Syntax
：
:measure:voltage:DC:digit?
:measure:voltage:DC:digit
□
{INC|DEC|5|6|7}
Function
：
The command queries and sets the digit of DC voltage.
