Scaling of frequency measurements in IS1 DTM und I.S.Wizard:
.
all DIM with Frequency (9470/3x in comp. mode)
Phys. 0
– 100% correlate digital 0 – 20000
DIOM 9470/3x (IS1+)
Phys. 0
– 100% correlate digital 0 – 40000
Signal in case of error:
freeze (Initial value 0)
Diagnosis:
status und channel diagnosis
Behavior in case of too high input frequencies:
If the input frequency is higher than the maximum of the selected measurement range, input pulses can be
lost. In this case the measured value is smaller as the existing frequency at the input. No alarm is generated.
Signal Filter:
The measured frequency signal can be filtered by the DIOM 9470/3x to reduce jitter.
Additionally a pulse extension function is executed for the DI signals.
