A positive transition occurs when a condition makes a transition fromunasserted to asserted (a low to a high state). Bits in the event register arelatched, and once set, they remain set until cleared by aSTATus:QUEStionable:CURRent:EVENt? query or *CLS (clear status). There is nobuffering; so while an event bit is set, subsequent events corresponding to thatbit are ignored. Event registers are read only.Returned DataComments– Refer to STATus:QUEStionable:CURRent:CONDition? for a description ofeach bit in the CURRent status group.Error ConditionsThe following table lists the most common error conditions and causes. Errornumbers and corresponding messages can be found using SYSTem:ERRor?query.Reset Condition*RST does not affect the status system, use *CLS to clear all event registers.Related CommandsSTATus:QUEStionable:CURRent:CONDition?,STATus:QUEStionable:CURRent:ENABle, *CLSType Range Default Descriptionint16 0 - 32767 none Bit mask indicating which events are set (1) orcleared (0) for the CURRent status group.Number Message Probable Cause-241 “Hardware missing” power supply doesn’t support currentmeasurements
