STATus:PRESet
Description Sets all bits to zero in the Meter’s Questionable Data enable register.
Examples STAT:PRES Sets all bits to zero.
*CLS
Description Sets all bits to zero in the Meter’s status byte register and all event
registers. Also clears the error queue.
Examples *CLS Sets all bits to zero and clear error queue.
*ESE <enable value>
Description Enables or disables bits in the Meter’s Standard Event enable register.
Parameters <n> = 0 to 255 Binary-weighted decimal value representing the
bits to set in the register. Although this register
has 8 bits and will accept a number from 0 to
255, only bits 0, 2 through 5, and 7 are used.
Examples *ESE 160 Sets bits 5 and 7 to one and all other bits to zero.
*ESE?
Description Retrieves the value in the Meter’s Standard Event enable register.
Examples *ESE? Retrieves a binary-weighted decimal value
representing the bits set in the Standard Event
enable register.
*ESR?
Description Retrieves the value in the Meter’s Standard Event register.
Examples *ESR? Retrieves a binary-weighted decimal value
representing the bits set in the Standard Event
register.
*OPC
Description Sets bit 0 (Operation complete) in the Meter’s Standard Event register.
Examples *OPC Sets bit 0 in the Standard Event register.
*OPC?
Description Returns a one to the Meter’s output buffer.
Examples *OPC? A “1” is placed in the output buffer of the Meter.
*PSC <n>
Description Enables or disables the clearing of the Status Byte Enable register and
Standard Event Enable register when Meter power is turned on. This
setting is stored in non-volatile memory.
Parameters <n> = 0 Disables clearing Status Byte and Standard
Event Enable register at power-up.
1 Enables clearing Status Byte and Standard Event
Enable register at power-up.
