RIGOL

Programming Guide for DM3000

2-9

Function

Query the current range of DC voltage measurement.
The query returns 0, 1, 2, 3 or 4.

6. :MEASure:VOLTage:DC:IMPEdance
Syntax

:MEASure:VOLTage:DC:IMPEdance?
:MEASure:VOLTage:DC:IMPEdance {10M|10G}

Function

Set the DC impedance to 10MΩ or >10GΩ.
The query returns 10M or 10G.

Explanation For DM306x, “>10G” is available only on 200 mV, 2 V and 20 V ranges

of DC voltage. For DM305x, “>10G” is available only on 400 mV, 4 V
and 40 V ranges of DC voltage.

7. :MEASure:VOLTage:DC:DIGIt
Syntax

:MEASure:VOLTage:DC:DIGIt?
:MEASure:VOLTage:DC:DIGIt {INC|DEC|5|6|7}

Function

Set the display digit of DC voltage measurement value.
The query returns 5, 6 or 7.

Explanation  DEC and INC settings are invalid when the display digits are 5 and

7, respectively.

 The definition of each parameter is as follows.

Parameter

Explanation

Note

INC

increase the digit by one

DEC

decrease the digit by one

the digit is 5

the digit is 6

the digit is 7

DM305x only accepts and

don’t response to this

value, the return value is

still 6.

Example

Set the display digit of DC voltage measurement to 6:
:MEASure:VOLTage:DC:DIGIt 6
Decrease the display digit by one:
:MEASure:VOLTage:DC:DIGIt DEC

8. :MEASure:VOLTage:DC:RATIo?
Syntax

:MEASure:VOLTage:DC:RATIo?
