STATus:QUEStionable:CONDition?
This command queries the Questionable Status condition 
register to check CV or CC mode of the power supply. The 
power supply returns a decimal value which corresponds to 
the binary- weighted sum of all bits in the register. These 
bits are not latched. If 0 is returned, the power supply is in 
output off or unregulated state. If 1 is returned, the power 
supply is in the CC operating mode and if 2 is returned, the 
power supply is in the CV operating mode. If 3 is returned, 
the power supply is in failure.

This command queries the Questionable Status event

Enable register. The selected bits are then reported to the
