The Questionable Status Register
The questionable status register provides information relate to the abnormal operation
of the power supply. When Bit 0 is 1. the power supply is in constant voltage mode
and when Bit 1 is 1, the power supply is in constant current mode. Bit 4 reflects
power supply’s operating temperature. When bit 9 is 1, it indicates that the power
supply is in over-voltage state and its over-voltage circuit begins to work. Query the
value of this register with STATus:QUEStionable? Command.
