4 Operating the Meter Using the Computer Interface Status Registers The ESE is a mask register that allows the host to enable or disable (mask) each bit in the ESR. When a bit in the ESE is set to 1, the corresponding bit in the ESR is enabled. When any enabled bit in the ESR changes from 0 to 1, the ESB bit in the STB also changes to 1. When the ESR is read using the *ESR? command or cleared using the *CLS command, the ESB bit in the STB returns to 0.
