Got 17300 error when execute IVI step in TestStand

[yangyang-rexxar]

Hi all

This is a PCBA test platform,, a 4072 card is used for two sockets, I locked the DMM blocks in order to have just a socket access it at same time.

but the DMM read step type still often has 17300 error, value invalid or out of range, if run only one socket, did not see same problem.

Confused on this.

After analysis, the error is caused by "out of range", I am aware of the dmm is set to autorange mode, I am not so sure why it over range, during test process, I measure related probes manually, a voltage is 12.60V, but dmm get a 1.5v value, I do not know why. If restart the sequence, the problem will disappear, sometimes occur again.

Hi Paul,

Are you in Trigger Mode. It maybe that because you DDM is not responsing quick enough because you connection are after the DDM configure and therefore it hasn't auto ranged until after the next trigger event.

Hi Farmer

The DMM is configed to immediately trigger mode, see attachment, according to the help, immediate means DMM dose not wait for any trigger signal, just read it as soon as the "Read DMM" running.

Paul,

You could try changing the Read to a Fetch and then insert an IVI DMM : Initiate step followed by a small delay step before the Fetch step.
