:STATus:QUEStionable[:EVENt]?
Syntax :STATus:QUEStionable[:EVENt]?
Description Query the event register of the questionable status register.
Explanation  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 questionable status register of the
multi-channel models and single-channel model and their corresponding
decimal values, refer to Table 1-1 and Table 1-4 respectively.
For example, take the single-channel model DP811A as an example. If the
instrument is in CC mode and OTP occured, the bit0 (Voltage, CC mode) and
bit4 (Overtemperature) in the event register of the questionable status register
are set and this command returns 17 (according to 2 0 +2 4 =17).
 The bits in the event register of the 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, 17.
Example :STAT:QUES? /*Query the event register of the questionable status register and
the query returns 17*/
