ERR?
Sequential Overlapped Coupled IEEE-488 RS-232
x x x x

(Error query) Returns the first error code contained in the Calibrator error queue, then
removes that error code from the queue. Following the error code is an explanation of the
error code, similar to but sometimes containing more specific information than the
EXPLAIN?
command. The explanation sent in response to this query can contain
variables specific to a particular error event. See Appendix E for a list of error codes and
error messages.
A zero value is returned when the error queue is empty. To read the entire contents of the
error queue, repeat
ERR?
until the response
0,”No Error”
is returned. For terminal
users, the error queue Returns for
ERR?
is always
0,”No Error”
because error
messages are returned instead of queued.
Response: <value>, (error code value)
<string> (text string explaining the error)
Example:
ERR?
returns
0,”No Error”
Returns
0,”No Error”
when the error queue is empty.

Chooses the error reference for error calculations.
Parameter:
NOMINAL
Sets the reference to the nominal value
TRUVAL
Sets the reference to the output value

Returns the error reference for error calculations.
Response:
NOMINAL
The nominal value is used as the error reference
TRUVAL
The output value is used as the error reference
ERR_UNIT

(UUT Error Unit Thresh Hold command) Chooses how UUT error is shown (this iS
nonvolatile).

GT100
UUT error is displayed in % above 100 ppm, ppm below
GT10
UUT error is displayed in % above 10 ppm, ppm below
PPM
UUT error is displayed in ppm always
PCT
UUT error is displayed in % always
