maximum of 256 characters may be sent as a response to this query. Negative error messages
(< 0) are defined in the SCPI Standard. Positive error message (> 0) are instrument specific.
The table below indicates the error query responses that are be supported.
Error Message Description
100, "Test Failed"
Test performed returned FAIL result
If the number of measurements taken is 5 (MEAS:VOLT:AC? 5)
and reading #1 fails while readings 2, 3, 4 and 5 pass, the
tester will still report a FAIL result. This test failed flag is
latched until the message is read at which time it is cleared.
For the Auto-Line option, when performing a measurement
(MEAS:VOLT:AC? 1) and cell #1 and #3 happen to fail, the
message queue will contain a 100 error message for each cell
number that failed.

message will contain PASS or FAIL indications for each cell.
