2. If more than 20 errors have occurred, the last error stored in the queue (the most
recent error) is replaced with -350, “Too many errors”. No additional errors are stored
until you read or remove errors from the queue. If no errors have occurred when you
execute this command, the power supply responds with “+0”, “No error”.
3. The error queue is cleared when the power has been off or a *CLS (clear status)
command has been executed. The *RST (reset) command does not clear the error
queue.
STATus:QUEStionable[:EVENt]?
This command queries the questionable status event register. The power supply
returns a decimal value which corresponds to the binary-weighted sum of all bits in
the register.
STATus:QUEStionable:ENABle <
enable value
>
This command enables or disables bits in the questionable status event register. The
selected bits are then reported to the status byte.
STATus:QUEStionable:ENABle?
This command queries the questionable status enable register. The power supply
returns a decimal value representing the bits set in the enable register and
corresponding to the binary-weighted sum of all bits in the register.
*CLS
This command clears all event registers and status yte register.
*ESE <
enable value
>
This command enables bits in the standard event enable register. The selected bits are
then reported to the status byte.
*ESE?
This command queries the standard event enable register. The power supply returns a
decimal value which corresponds to the binary-weighted sum of all bits in the register.
*ESR?
This command queries the standard event register. The power supply returns a
decimal value which corresponds to the binary-weighted sum of all bits in the register.
*OPC
This command sets the “Operation Complete” bit (bit 0) of the standard event register
after the command is executed.
*PSC { 0 | 1 }
(Power-on status clear.) This command clears the status byte and the standard event
