Syntax:
STATus:OPERation:CONDition?
Example:
STAT:OPER:COND?
Response: <nnn>, a number from 0 to 255
Example: 128 (local mode with the output off (because CV and CC both zero))
7.8.12. Set the Operational Condition Enable Register
When one or more bits in the Operational Condition Condition Register (see 7.8.11 above)
are set, a bit can be set in the Status Byte (*STB,see section 7.8.5). This is done by setting
bits in the enable register. Changing the value of the enable register has no affect on the
value in the condition register
Syntax:
STATus:OPERation:ENABle <nn>
Parameter:
<nnn>
Example:
STAT:OPER:ENAB 1
Query:
STAT:OPER:ENAB?
7.8.13. Read the Operational Condition Event Register
This is a settings and modes event register, which means bits are set to "1" when a
condition occurs and they are not cleared until the register value is read or the *CLS
command is sent. For the condition to be latched as an event, the event bit must be enabled
as described in section 7.8.12 above.
The bit assignments are the same as the Operational Condition Condition Register,
described in section 7.8.11 above
Syntax:
STATus:OPERation[:EVENt]?
Example:
STAT:OPER?
Response: <nnn>, a number from 0 to 255
Example: 2 (the supply went into constant current mode)
7.8.14. Read the Questionable Condition Condition Register
This register reports fault conditions which will cause the power supply output to turn off.
The faults include:
− User settable faults (enable, shut-down, over-voltage, fold-back, output off)
− Environmental faults (over-temperature, AC fail)
− Instrument summary fault bit (for RS-485 multi-drop chain, see section 9)
− Internal firmware faults (four faults)
This is a conditional register. The bits are set to "1" when the fault occurs and cleared when
the fault is cleared. The values are read-only. See the Technical Manual for more details on
faults.
is a number from 0 to 255. The bit assignments are the
same as the table above
will cause bit 7 in the Status Byte to be set if
the supply goes into constant-voltage mode
will return 1 in the example
