*ESE?
(Event Status Enable query) Returns the contents of the Event Status Enable (ESE)
register. (See "Event Status Enable Register (ESE)" in Chapter 5)
Response:
<value> (decimal equivalent of the ESE byte, 0 to 255)
Example:
*ESE? returns 133
Returns decimal 133 (binary 10000101) when bits 7 (PON), 2 (QYE), 1 (OPC) are
enabled.

*ESR?
(Event Status Register query) Returns the contents of the Event Status Register (ESR)
and clears the register. (See Event Status Register (ESR)" in Chapter 5)
Response:
<value> (decimal equivalent of the ESR byte, 0 to 255)
Example:
*ESR? returns 189
Returns decimal 189 (binary 10111101) when bits 7 (PON), 5 (CME), 4 (EXE), 3
(DDE), 2 (QYE) and 0 (OPC) are enabled.

EXPLAIN?
(Explain Error query) Explains an error code. This command returns a string that
explains the error code furnished as the parameter. The error code (same as the
parameter) is originally obtained by sending the FAULT? query. (See the ERR?
command, which returns both the error code and the explanation string.) See Appendix E
for a list of error codes and error messages.
Parameter:
<value> if the error code (an integer)
Response:
<string> that explains the error code, with the parameter (if there is one)
Example:
EXPLAIN? 539 returns "Can't change compensation now."
Returns the explanation of error 539: "Can't change compensation now."

EXTGUARD
(External guardcommand) Connects or disconnects the internal guard shield from the LO
binding post.
Parameter:
ON
OFF
Once set, the Calibrator retains the external guard setting until power off or reset.
