numeric
Pulse factor for int. and ext. flow totalization,
Range 0.001–1000 pulses per selected flow unit,
max. count frequency 10 kHz.
Note: The max. count frequency and the pulse factor are checked
by the software, if out of range Error 40
“Frequency >10 kHz” is displayed.
numeric
For external pulse output. Range: 0.0032 ms – 2000 ms in
multiples of 0.0032 ms. The max. allow. pulse width is checked
by the software and corrected if required.
numeric
Range 0–10 % of the flow range end value setting, applies to the
displayed values and all outputs.
The switching limits for the zero return incorporate a
hysteresis of 0.5 %.
numeric
Range 0.100–99.99 s. Response time for 5 = 0–99 %
flowrate change.

On/off. Standard is off. If the output signal is noisy, turn the filter
on and select a damping time > 2.4 sec. For applications with
piston or diaphragm pumps (pulsating flow) a special algorithm is
required. Faster flowrate measurements are achieved at this
higher excitation frequency and utilizing difference totalizers so
that the reverse flow values can be subtracted, i.e. the totalizer
runs in reverse. The filter should be set to “On” for pulsating flows
applications (for a pulsation free output).

Zero value check (required when retrofitting older flowmeter
primaries).
Manual entry, e.g. when a converter is exchanged.
Valve must be closed, flowrate must be at 0. The automatic
adjustment is initiated with ENTER. The zero value limits are
±1500 Hz. If the value exceeds these limits, the zero adjustment
value is not accepted.
