Clears all event registers summarized in the status byte,
except for "Message Available," which is cleared only if *CLS
is the first message in the command line.
Sets "Event Status Enable Register" to , an integer
between 0 and 255. is an integer whose binary
equivalent corresponds to the state (1 or 0) of bits in the
register. If is not between 0 and 255, an Execution
Error is generated.
EXAMPLE: decimal 16 converts to binary 00010000. Sets bit
4 (EXE) in ESE to 1.
Meter returns the of the "Event Status Enable
Register" set by the *ESE command. is an integer
whose binary equivalent corresponds to the state (1 or 0) of
bits in the register.
Meter returns the of the "Event Status Register" and
then clears it. is an integer whose binary equivalent
corresponds to the state (1 or 0) of bits in the register.
Meter returns the identification code of the meter as four
fields separated by commas. These fields are: manufacturer
("FLUKE"); model ("45"); seven-digit serial number; version of
main software and version of display software.
Meter sets the Operation Complete bit in the Standard Event
Status Register when parsed.
Meter places an ASCII "1 " In The output Queue when
parsed.
Meter performs power-up reset except that the state of IEEE-
488 interface is unchanged, including: 1) instrument address,
2) Status Byte and, 3) Event Status Register.
