12 Advanced Measuring Functions
12.6 Measurement of Transient Processes (FastFood mode)
The FastFood mode allows to measure flows with high dynamics. The continuous adap-
tation to changing measuring conditions which takes place in the normal measuring
mode is only partially realized in FastFood mode.
The sound velocity of the medium is not measured. The sound velocity stored in the in-
ternal database will be used instead, taking into account the medium temperature en-
tered in the program branch
PARAMETER
(or the measured temperature if the medium
temperature is measured).
A change of measuring channel is not possible. The inputs and outputs can still be used.
The measured values are stored as usual. The FastFood mode has to be enabled and
activated.
12.6.1 Enabling/Disabling the FastFood Mode
12.6.2 Storage Rate of the FastFood Mode
12.6.3 Activating/Deactivating the FastFood Mode
If the FastFood mode is enabled and a measurement started, the normal measuring
mode is still running (i.e. multi-channel measurement with permanent adaptation to the
measuring conditions). If the data memory is activated, the measured values will not be
stored.
If the data memory is activated, a new data set will be defined and storing of measured
values will be started. If the FastFood mode is deactivated or if the measurement is inter-
rupted, storing will be stopped.
Press key C. Enter HotCode 007022. The menu item
