*ESR?

Query the event register in this register group. This is a read-only register. Once a bit is set, it remains set until cleared by a *CLS (clear status) command. A query of this register returns a decimal value which corresponds to the binary-weighted sum of all bits set in the register.

*ESE <zv	>
*ESE?

Enable bits in the enable register in this register group. The selected bits are then reported to the Status Byte. A *CLS (clear status) clear the enable register but it does clear all bits in the event register.

A STATus:PRESet y clear the bits in the Standard Event enable register. To enable bits in the enable register, you must write a decimal value which corresponds to the binary-weighted sum of the bits you wish to enable in the register.

The *ESE? query returns a decimal value which corresponds to the binary-weighted sum of all bits enabled by the *ESE command.
