Hi my name is Said and I work in the National Institute of Industrial Technology of Argentina, in a calibration lab. We have a Wavetek 9100 Calibrator, Agilent 34401A Digital Multimeter and a NI GPIB IEEE-488-2 board. I have a problem with the Calibrator driver, in the transition from 90 V to 110 V in the DC and AC Voltage the instrument starts to ring an alarm and the program shows me the follow message: "Error -1073807339 occurred at VISA Read in wt9100 Error Query.vi->wt9100 Configure Output State.vi->wavetek multipoint VCC con array desde txt modificado 1.vi" and "Possible reason(s):
VISA: (Hex 0xBFFF0015) Timeout expired before operation completed."
