weights. The error conditions and their weights are:
Power-on value = 32767 (all enabled).
Default value = 32767 (all enabled).
Remarks • When an error occurs, it sets the corresponding bit in the error register
regardless of whether or not it has been enabled by the EMASK command.
Disabling an error bit prevents it from setting the error bit in the status register
only, and thereby generating a service request.
• Query Command The EMASK? query command returns the weighted sum of
all enabled error conditions (see example below).
• Related Commands: AUXERR?, ERR?, ERRSTR?, RQS, STB?
