question about 6430

already solved it.

Hi,&#160;<br> <br> I want to set some parameters by SCPI command<br> :SOUR:VOLT 5<br> :SENS:CURR:RANG 10E-12<br> :SENS:CURR:PROT 105E-12<br> and then to check error<br> :SYST:ERR?<br> and then I get error code : 822, error message &quot;Too small for sense range&quot;<br> Can any one tell me how to set the range and compliance value?<br> Thank you so much.

Glad to hear you solved it.

FYI for others, if you turn off auto range for current measure, and set a fixed range, the allowed values of current compliance limit must be within that selected measure range.  This is why too small for sense range error is raised.

If auto range is on, then it is possible to have a much higher value for current compliance than the presently in use measure range by the auto range algorithm.

Thank you for your explain.
