(-221) Settings conflict
Indicates that a legal program data element was parsed
but could not be executed due to the current device
state (see IEEE 488.2 11.5.1.1.5).
(-220) Parameter error
Indicates that a program data element related error
has occurred. This particular error message is used if
the device cannot detect more specific errors.
(-215) Arm deadlock
Indicates that the arm source for the initiation of a
measurement is set to GET and a subsequent
measurement query is received. The measurement
cannot begin until a GET is received, but the GET would
cause an INTERRUPTED error.
(-214) Trigger deadlock
Indicates that a trigger source for the initiation of a
measurement is set to GET and a subsequent
measurement query is received. The measurement
cannot begin until a GET is received, but the GET would
cause an INTERRUPTED error.
(-213) Init ignored
Indicates that a request for a measurement initiation
was ignored as another measurement was already in
progress.
(-212) Arm ignored
Indicates that an arming signal was received and
recognized by the device, but was ignored.
(-211) Trigger ignored
Indicates that a GET, *TRG, or triggering signal was
received and recognized by the device, but was ignored
because of device timing considerations (for example,
the device was not ready to respond).
(-210) Trigger error
Indicates that a GET, *TRG, or a triggering signal
could not be executed due to an error.
(-202) Settings lost due to rtl
Indicates that a setting associated with a hard local
control (see IEEE 488.2, 5.6.15) was lost when the
device changed to LOCS from REMS or to LWLS from
RWLS.
