how can I Keithley 6517 right trigger

[constantine1964]

I use labview 8.2 to mess current of  resistance and I see the  Keithley 6517 always appear "Trigger isnored " at display.

The step function don't work ,too.

I use the SCPI oder ":TSEQ:STSW:STAR -1; :TSEQ:STSW:STOP 1;: TSEQ:STSW:STEP 0.01; "and I don't know where is my mistake.

Please take a look and give  me some advice,I am a rookie with Labview .
