SYSTem:ERRor?
Queries the error buffer of the Model 430 Programmer. Up to 10 errors
are stored in the error buffer. Errors are retrieved in first-in-first-out
(FIFO) order. The error buffer is cleared by the
*CLS
(clear status)
command or when the power is cycled. Errors are also cleared as they
are read. See page 178 for a complete description of the error buffer and
messages.

The status system register groups and commands are illustrated the
figure on page 138.
•
*STB?
Returns the contents of the Status Byte register. The
*STB?
command
does not clear the “Summary Bit” (bit 6) of the Status Byte register.
•
*SRE <
enable_value
>
Enables bits in the Status Byte register to be reported in the “Summary
Bit” (bit 6) of the Status Byte register. To enable bits, you must write a
decimal
<
enable_value
>
which corresponds to the binary-weighted sum
of the bits you wish to enable. Refer to page 139 for more information.
For example, to enable quench detections only in the “Summary Bit” of
the Status Byte register, send the command:
*SRE 4
.
•
*SRE?
The
*SRE?
query returns a decimal sum which corresponds to the
binary-weighted sum of the bits enabled by the last
*SRE
command.
•
*CLS
Clears the Standard Event register and the error buffer.
•
*ESR?
Returns a decimal sum which corresponds to the binary-weighted sum
of the contents of the Standard Event register.
•
*ESE <
enable_value
>
Enables bits in the Standard Event register to be reported in the
“Standard Event” bit (bit 5) of the Status Byte register. To enable bits, you
must write a decimal
<
enable_value
>
which corresponds to the binary-
weighted sum of the bits you wish to enable. Refer to page 141 for more
