Overview

Owon has launched a new low-cost (~150$) benchtop multimeter (XDM1041) with an RS232 interface.

I was searching for a low-cost programmable multimeter for one of my test automation projects and found this on toolworld.

Itโ€™s fairly new, the documentation is not yet available on their website. It took me some time to figure all the details and make it work.

Explainer Video

I have created two videos, one giving the details about all the major features this multimeter has and a comparison with Fluke 287 True RMS Multimeter and another one is to show how to connect this multimeter with PC using OWONโ€™s PC Software or control using serial commands.

SCPI Commands

OWON XDM1041 Programmable Multimeter 2

Commands were nowhere available so I used a serial port sniffer to figure it out and I am sharing so you donโ€™t waste your time in figuring it out.

Mode Configuration Commands (every command need 0x0

  • *IDN? (this will give manufacturers details)
  • CONFigure:VOLT:DC
  • CONFigure:VOLT:AC
  • CONFigure:CURR:DC
  • CONFigure:CURR:AC
  • CONFigure:RES
  • CONFigure:CONT
  • CONFigure:DIOD
  • CONFigure:CAP
  • CONFigure:FREQ
  • CONFigure:PER
  • CONFigure:TEMP
  • RATE S (for slow sampling)
  • RATE M (for medium sampling)
  • RATE F (for high sampling)

For Range selection in each mode like DC voltage or AC Voltage you need to send range command

  • RANGE 1<LF> will set to 50mv range of DC volt mode. if you want to set into Auto mode you need to send AUTO<LF> command.

Measurement Commands

  • MEAS1:SHOW?

NOTE: Each command should use a linefeed character at the end of each command like CONFigure:VOLT:DC<LF>
