ERRSTR?
Error string query. The ERRSTR? command reads the least significant set bit in
either the error register or the auxiliary error register and then clears the bit. The
ERRSTR? command returns two responses separated by a comma. The first
response is an error number (100 Series = error register; 200 Series = auxiliary
error register) and the second response is a message (string) explaining the error.

register. If more than one bit is set in a register, you must execute ERRSTR?
repetitively to read and clear each set bit. After all set bits have been read and
cleared (or if there were no set bits in either register), the ERRSTR? command
returns 0,"NO ERROR". When the auxiliary and error registers are cleared, the
error bit in the status register (bit 5) will also be cleared.
auxiliary error register are set. In this case, the ERRSTR? command reads and
clears each set bit in the auxiliary error register first. When all auxiliary errors
have been read, bit 0 in the error register is cleared and the ERRSTR?
command can then be used to read any remaining errors in the error register.
