2.4.2
Span test
For the electronic zero check, a time difference from both transfer directions is determined
and computed with the air temperature, active measuring path and sound velocity
installation parameters into a velocity offset at the zero point. This offset is then added to
the selected span value and output. The span value can be set with the SOPAS ET operating
program in the range from 50 to 70% in steps of 1% (standard setting ex factory 70%). If all
system components are intact, the entire measuring system reacts as intended.
2.4.3
Analog output of check cycle
The check cycle‘s output is as follows:
●
90 s zero value (live zero)
●
90 s span value
●
The output duration of 90 s each time is the standard setting ex factory. It
can be changed in the SOPAS ET program.
●
The output is suitable for velocity-dependent measured values only (gas
velocity, volume flow act., volume flow std.).
