Continuation „Mode Process Time“:
WAIT TIME (S)
This parameter defines the period time of the lowest frequency, accordingly the time between two rising signal
edges detecting frequency 0 Hz. Frequencies with a period time higher than the set “WAIT TIME” will be detected as
frequency = 0 Hz.
0.01
Frequency = 0 Hz, for frequencies below 100 Hz
1.00
Default value
99.99
Frequency = 0 Hz, for frequencies below 0,1 Hz
STANDSTILL TIME (S)
This parameter defines the time setting for standstill definition.
A time of xx.xx seconds after detection " frequency = 0 Hz " the unit signals "standstill" and reactivates the start-up-
delays. Stand still detection can be set in PRESELECT MENU.
0.00
Shortest time
…
99.99
Longest time
AVERAGE FILTER
Selectable average or filter function to avoid measuring fluctuations by unstable frequencies. At setting 1 to 4 a
floating average calculation is preformed. At settings 5 to 8, the device uses an exponential filter. The time
constant T (63%) corresponds to the sampling cycles.
For example: If SAMPLING TIME = 0,1 s and AVERAGE FILTER = Exponential filter, T (63 %) = 2x SAMPLING TIME,
after 0,2 seconds, 63% of the step size are reached
0
No average value will be created
1
2 numbers of floating average cycles
2
4 numbers of floating average cycles
3
8 numbers of floating average cycles
4
16 numbers of floating average cycles
5
Exponential filter, T (63 %) = 2x SAMPLING TIME
6
Exponential filter, T (63 %) = 4x SAMPLING TIME
7
Exponential filter, T (63 %) = 8x SAMPLING TIME
8
Exponential filter, T (63 %) = 16x SAMPLING TIME
