Programming Guide for DM3000 2-10
Function The query returns the ratio of two DC voltages in scientific notation, for
example, +1.74214858E-01.
Explanation The instrument should input two DC voltages at the same time.
9. :MEASure:VOLTage:DC:RATIo:DIGIt
Syntax
:MEASure:VOLTage:DC:RATIo:DIGIt?
:MEASure:VOLTage:DC:RATIo:DIGIt {INC|DEC|5|6|7}
Function Set the display digit for the ratio of two DC voltages.
The query returns 5, 6 or 7.
Explanation Refer to the “Explanation” in :MEASure:VOLTage:DC:DIGIt.
Example
Set the ratio display digit to 6:
:MEASure:VOLTage:DC:RATIo:DIGIt 6
Decrease the display digit by one:
:MEASure:VOLTage:DC:RATIo:DIGIt DEC
10. :MEASure:VOLTage:AC?
Syntax
:MEASure:VOLTage:AC?
Function The query returns the AC voltage measurement value in the scientific
notation (for example, +6.59000527E-03) and the unit is V.
11. :MEASure:VOLTage:AC
Syntax
:MEASure:VOLTage:AC {0|1|2|3|4|MIN|MAX|DEF}
Function Set the range of AC voltage measurement.
Explanation The range corresponding to each parameter is as follows.
Parameter Range
0 200 mV
1 2 V
2 20 V
3 200 V
4 750 V
MIN 200 mV
MAX 750 V
DEF 20 V
Example Set the range to the minimum:
:MEASure:VOLTage:AC 0 or
:MEASure:VOLTage:AC MIN
