Syntax :STATus:QUEStionable:INSTrument:ISUMmary[][:EVENt]?
Description Query the event register of the specified channel SUMMARY questionable status
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 event 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) and clears the status of 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, if CH1 of the instrument changes from CV (constant voltage)
mode to CC (constant current) mode, the bit0 (VOLTAGE, CC mode) in the
event register of the channel questionable status SUMMARY register are set
and this command returns 1 (according to 2 0 =1).
 The bits in the event register of the channel questionable status SUMMARY
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 event register of the channel questionable status SUMMARY
register, for example, 1.
Example :STAT:QUES:INST:ISUM1? /*Query the event register of the CH1 questionable
status SUMMARY register and the query returns
1*/
