Thank every one of you!
I'm back again, and seem to have found the answer with your help.

I enable command logging in Event Log and found the offending command just like the video demonstration. I found the SCPI command "SENS:VOLT:RANG AUTO ON" and "SENS:VOLT:INP AUTO " seem to be in conflict, because the command "SENS:VOLT:RANG AUTO ON" will report Error 1135 when command "SENS:VOLT:INP AUTO " is used, but the command "SENS:VOLT:RANG 15" will not report Error 1135 when command "SENS:VOLT:INP AUTO " is used. Please see the attached picture for details, the"Report Error 1135.jpg" and "Not report  Error 1135.jpg".

I read a paragraph in the DMM6500 programming manual about "SENS:VOLT:INP AUTO" that seems to be able to explain the above phenomena. I've copied it here:  

My understanding is that if  the command "SENS:VOLT:INP AUTO" is used, then "SENS:VOLT:RANG number" can be used, not "SENS:VOLT:RANG AUTO ON" .  Because "SENS:VOLT:INP AUTO" needs to manually select the voltage range, such as select  100 mV to 10 V range, or 100 V and 1000 V ranges.

That's my understanding. Correct me if I'm wrong.

Hi McKiney Ty, 

Do you mean that the SCPI command entered has a syntax error? There is typo or invalid character? Such as ,
"SENS:FUNC 'VOLT:DC'" 
"SENS:VOLT:RANG AUTO ON"

Or do you mean is Visa command has a syntax error? 

 

Hi friends:

We have a problem about DMM6500  pops up an error code 1135 when using remote control, but it doesn't seem to affect the measurement.
 We want to know what's the reason for this, how to solve it?  We did not find any reference to error code 1135 in the programming manual.
Does anyone know how to fix this? Does anyone have this same problem?
Thanks for you help!
