6.1.2.10 Output String Setting
PRESS? & OUTPUT_MASK -
PRESS? is a programmable output query that returns an ASCII string based on the selections set by
the OUTPUT_MASK variable. The selected parameters will populate the output string with commas separating the variables in the
order in which they appear in the following table:

Table 6.1.2.10 - Query Mode Mask Description
6.1.2.11 Burst Mode Output Setting
BURST_MASK – This sets the mask of the output parameters in burst output mode.
The transducer has the ability to continually output a limited set of binary data based on the selections set by the BURST_MASK
variable. The selected parameters will populate the output string with no delimiters in the order in which they appear in the
following table:
