Parameter:
<value> (decimal equivalent of the ESE byte, 0 to 255)
Example:
*ESE 140

(Event Status Enable query) Shows 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?
shows
133
Shows decimal 133 (binary
10000101
) when bits 7 (PON), 2 (QYE), 1 (OPC) are
enabled.

(Event Status Register query) Shows 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?
shows
189
Shows decimal 189 (binary
10111101
) when bits 7 (PON), 5 (CME), 4 (EXE), 3
(DDE), 2 (QYE) and 0 (OPC) are enabled.

(Explain Error query) Tells you about an error code. This command shows a string that
tells you about the error code given as the parameter. The error code (same as the
parameter) originally comes from sending the
FAULT?
query. (See the
ERR?
command,
which shows 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 tells you about the error code, with the parameter (if there is
one) as a percent sign followed by d (integer parameter),
f (floating point parameter), or s (string parameter)
Example:
EXPLAIN? 539
shows “
Can’t change compensation now.
”
Shows the explanation of error 539: “Can’t change compensation now.”

(Fault query) Shows the first error code contained in the Calibrator error queue, then
remove that error from the queue. After you get the error code, use the
EXPLAIN?
command to see an explanation. A zero value is shown when the error queue is empty. To
read the complete contents of the error queue, do
FAULT?
until the response is 0. (Only
system errors appear in the error queue.)
Response:
<value> of the error code
Example:
FAULT?
shows
539
Shows the first error code in the error queue, number 539. To see an explanation of the
error, record the command
EXPLAIN? 539
.
