:STATus:QUEStionable:INSTrument[:EVENt]?
Syntax :STATus:QUEStionable:INSTrument[:EVENt]?
Description Query the event register of the channel questionable status register.
Explanation  This command is only applicable to multi-channel models.
 This command returns a decimal value (corresponding to the sum of the binary
weights of all the bits in the register) and clears the status of the register. For
the definitions of the bits in the channel questionable status register and their
corresponding decimal values, refer to Table 1-2.
For example, if questionable events occur on CH1 and CH3 of the instrument,
the bit1 (INST1 event summary, event SUMMARY bit of CH1) and bit3 (INST3
Event Summary, event SUMMARY bit of CH3) in the event register of the channel
questionable status register are set and this command returns 10 (according to
2 1 +2 3 =10).
 The bits in the event register of the channel questionable status register are
latched and reading the register will clear it. You can also use the *CLS
command to clear the register.
Return Format The query returns a decimal value corresponding to the sum of the binary weights of
all the bits in the register, for example, 10.
Example :STAT:QUES:INST? /* Query the event register of the channel questionable
status register and the query returns 10*/

:STATus:QUEStionable:INSTrument:ISUMmary[]:COND?
Syntax :STATus:QUEStionable:INSTrument:ISUMmary[]:COND?
Description Query the condition register of the specified channel questionable status SUMMARY
register.
Parameter Name Type Range Default
[] Discrete 1|2|3 None
Explanation  This command is only applicable to multi-channel models. Multi-channel
models contain multiple channel questionable status SUMMARY registers and
[] represents the questionable status SUMMARY registers of CH1, CH2 and
CH3 respectively when it is 1, 2 and 3. When [] is omitted, the system
queries the condition register of the questionable status SUMMARY register of
the current channel.
 This command returns a decimal value corresponding to the sum of the binary
weights of all the bits in the register. For the definitions of the bits in the
channel questionable status SUMMARY register and their corresponding
decimal values, refer to Table 1-3.
For example, when the query returns 0, the power supply is turned off or in the
unregulated mode; when the query returns 1, the power supply is in CC mode;
when the query returns 2, the power supply is in CV mode; when the query
returns 3, power supply failure occurs.
Return Format The query returns a decimal value corresponding to the sum of the binary weights
of all the bits in the register, for example, 1.
Example :STAT:QUES:INST:ISUM1:COND? /*Query the condition register of the CH1
questionable status SUMMARY register and
the query returns 1*/
