Display of measured values
The measured values are displayed during the measurement as follows:
9.4.1
Value of the sound speed
The sound speed of the fluid can be displayed during the measurement by pressing key

Write down the fluid temperature as the sound speed depends on it. The value can be entered in the program branch
