Figure 8: Status registers and related commands
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 register.

Register.
