vrf How to retrieve DMM function unit?

Question asked by VRFuser on Sep 7, 2006
Hi, tried to read data as string ("READ TEST x STR"), but the output data is ("None, +14.91").
I've added a "BUS I/O Monitor" as u mentioned, from the  "BUS I/O Monitor" object, the output data vertically appear: 
configure:resistance:read? NONE, +14.91 <LF>
My script in "Direct I/O" as below:
WRITE TEXT":CONFigure:RESistance 0"
":WAI INTERNAL:2"
WRITE TEXT":READ?"EOL
READ TEXT x STR
 
The instrument is connected using GPIB, the small 'k' unit able to appear in DMM primary display, but when the command sent to DMM, my display sometimes will appear 14.91k, sometimes 14.91. Is it something need to do with the DMM register?
Another senerio is when my script stated as below, the function unit 'k' will appear statically with the output data in my display.
WRITE TEXT":CONFigure:CURrent:DC 0"
WRITE TEXT":CONFigure:RESistance 0"
":WAI INTERNAL:2"
WRITE TEXT":READ?"EOL
READ TEXT x STR
 
 
Thanks for help!

Hi,


I guess that your DMM outputs data as "14.91kOHM" and "14.91 kOHM".
If your program reads the data as REAL64 ("READ TEXT x REAL64"),
the former data will be "14.91k=14.91E+3" and the latter will be "14.91".

I recommend you to read data as string ("READ TEXT x STR") to check
DMM's output.
Or add a "BUS I/O Monitor" object to the VEE program in order to see the
data on the BUS.
