Programmable DC Power Supply 62000L Series User’s Manual
4-16
*CLS
This command is used to clear all event registers and Status Byte register.
*ESE <enable value>
This command is used to enable bits in the Standard Event Enable register. Then the selected
bits will be reported to the Status Byte.
*ESE?
This command is used to query the Standard Event Enable register. Then the power supply
will return a decimal value which conforms to the binary-weighted sum of all bits in the
register.
*ESR?
This command is used to query the Standard Event register. Then the power supply will return
a decimal value which conforms to the binary-weighted sum of all bits in the register.
*OPC
After this command is executed, the “OPC” bit, bit 0 of the Standard Event register, is set to
1..
*OPC?
After the command is executed, 1 is returned.
*PSC {0|1}
Enable/Disable power-on status clear function. By default, the PSC is enabled and the
Status Byte enable register and the Standard Event enable register are cleared while the
power supply is power on. Use command *PSC 0 to prevent the registers from been cleared
while power on.
*PSC?
This query command is used to query the power-on status clear setting. If PSC is enabled,
return 1. Otherwise return 0..
*SRE <enable value>
This command is used to set the Status Byte Enable register.
*SRE?
This command is used to query the Status Byte Enable register. Then the power supply will
return a binary-weighted decimal representing the bits set in the enable register.
*STB?
This command is used to query the Status Byte summary register. *STB? Is similar to a serial
poll, but its process is like any instrument command. Using this command will return the same
result as a serial poll, but the Request Service bit (bit 6) won’t be cleared if a serial poll has
occurred.
*WAI
This command is used to instruct the power supply to wait for all pending operations done
before executing additional commands over the remote interface. It’s used only in the
triggered mode.
