A string “+00000” read back (with the command ERROR) indicates that the error queue is
empty. In this case, a string “0000” displays on the front panel of the instrument.

Note
A string “+0” read back (with the command TEST) indicates that all the tests have passed. In
this case, a string “PASSED” displays on the front panel of the instrument.
