*ESR?
Syntax *ESR?
Description Query the event register of the standard event 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 this register. For
the definitions of the bits in the standard event register and their
corresponding decimal values, refer to Table 1-5.
For example, if query error and execution error currently occur in the
instrument, the bit2 (query error bit) and bit4 (execution error bit) in the event
register of the standard event register are set and this command returns 20
(according to 2 2 +2 4 =20).
 The bits in the event register of the standard event register are latched and
reading the register will clear it. You can also use the *CLS command to clear
this 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, 20.
Example *ESR? /*Query the event register of the standard event register and the query
