C.10 Status Reporting Commands
SYSTem:ERRor?
Query the multimeter’s error queue. Up to 20 errors can be stored in the
queue. Errors are retrieved in first-in-first out (FIFO) order. Each error
string may contain up to 80 characters.
STATus:QUEStionable:ENABle <enable value>
Enable bits in the Questionable Data enable register. The selected bits are then
reported to the Status Byte.
STATus:QUEStionable:ENABle?
Query the Questionable Data enable register. The multimeter returns a
binary-weighted decimal representing the bits set in the enable register.
STATus:QUEStionable:EVENt?
Query the Questionable Data event register. The multimeter returns a
decimal value which corresponds to the binary-weighted sum of all bits
set in the register.
