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.
