  • Page 97: Error Messages

    7. Error Messages You can check error by pressing error key in front panel. +0,"No error" There is no error. 7-1. Operating Error -10, "Invalid the DAC parameter" If setting value is out of DAC parameter, setting value and real output value is different. In that case, remove load directly.
  • Page 98 -23, "En route to cal the curr" This error occurs when someone send voltage calibration command during current calibration. -24, "Over volt min parameter" Voltage value is over the minimum value. Refer "4-5. CALIBRATE ' -25, "Under volt max parameter" Voltage value is under maximum value.

  • Page 99: Calibration Error

    -34, "Not allowed command under cal" Under calibration this command does not available. 7-4. Calibration Error If you do calibration, Read back calibration inside the product will be proceeded. -74, "ADC-V low limit over" Voltage value is over from ADC-V low limit. -75, "ADC-V high limit over"...

  • Page 100: Interface Commands Error

    -87, "Memory curr length error" There's an error in current data length(Digit). -88, "Not match volt length and limit" Voltage length setting value does not matched with limit value. -89, "Not match curr length and limit" Current length setting value does not matched with limit value. 7-6.
  • Page 101 -221, "Setting conflict" This error occurs because there's no option for this command. ex)POL N This command is for changing polarity. If you use this command with single polarity product, error 221 will occur. -222, "Out of data" Setting value is out of product spec. ex)volt 1000 Solution) volt 10 -223, "Incorrect error"...
