The CONDition register is a read-only register which monitors the present state of
the instrument. The CONDition register updates in real time and the inputs are not
latched or buffered. When a condition monitored by the CONDition register
becomes true, the bit for that condition also becomes true (1). When the condition
is false, the bit is 0.
The read-only EVENt register latches any false-to-true change in condition. Once
the bit in the EVENt register is set, it is no longer affected by changes in the
corresponding bit of the CONDition register. The bit remains set until the controller
reads it. The command *CLS (Clear Status) clears the EVENt registers.
