9.4 Empty and full pipe functions
9.4.1 Significance of ATC function
The heat meter cannot work normally without medium, so it is necessary to judge whether
the pipe is empty.
When the empty pipe alarm is abnormal (such as low medium conductivity), empty and full
pipe calibration is required. See 9.4.3 for operation steps.
9.4.2 The use of ATC sensitivity
When it is impossible to calibrate the empty pipe, the sensitivity of the empty pipe can be
modified to adjust the ability of the instrument to detect the empty pipe. The higher the
sensitivity of ATC, the easier it is to be judged as ATC. When there is air in the pipe, it is
necessary to set the sensitivity higher. When the sensitivity of empty pipe is 0, turn off the
empty pipe detection function.
