TABLE 6-9. Data Field in the EC100_Config_Notes Output Table
Data Field Name Units Description Data Field Included
press_source –
A parameter indicating the sensor used by
EC100 for ambient pressure (0 for EC100
Basic Barometer, 1 for user/custom
barometer, 2 for EC100 Enhanced
Barometer)
Always
diff_press_select –
A parameter indicating whether to report
ambient pressure (open-path system) or
differential pressure (closed-path system). It
should be set to 2, which will auto-select.
Always
sample_cell_press_type –
A parameter indicating whether the sample
cell pressure sensor is differential or
absolute. Set to 0 for EC155 gas head serial
numbers less than 2000, and set to 1 for
serial numbers 2000 and greater.
Always
tmpr_source –
A parameter indicating the sensor used by
EC100 for ambient temperature (0 for
EC100 Temperature Probe, no other values
valid)
