Fct. 1.1.4 TIMECONST
.
time constant for flow rate
Enter a low-pass filter time constant in seconds to be
applied to flow rate. A value of zero indicates that
low-pass filter is not to be applied. With this function
it is possible to compromise between a steady
indication (on display/current output) and response
time (to flow changes).
LIMITS - 0 to 20 seconds.
APPEARS - Always.
Fct. 1.2.0 DISPLAY
This submenu groups the display functions which
- Allow selection of units for all measured parameters.
- Select what parameters to include in display cycle.
- Select display mode (cyclic/non-cyclic) and error
messages to appear or not to appear in display cycle.
