The Event Status Enable Register is set by sending the program code *ESE, followed by an ASCII 3 digit
value (the value is determined by summing the weights of the bits to be checked). To read the current
setting of the Event Status Register, send the command *ESE?. The 8650A sends an ASCII 3 digit value
that describes the current state of the register (the value is determined by summing the weights of the
bits that are set).
