EXPLANATION OF SETUP MENU 5 - FLOWMETER
SIGNAL
51
With this setting the type of flowmeter output is selected. The settings with
LP (low-pass) filter are used to apply a build-in noise reduction.
Selections "active pulse" offer a detection level of 50% of the supply
voltage.

EXPLANATION OF SETUP MENU 6 - TEMPERATURE
DISPLAY
61
This setting is used to program the temperature unit which is shown to the
operator. This setting does not influence the actual calculations.
NO. OF WIRES
62
This setting is used to program the number of wires for the PT100
sensors.
FILTER
63
The analog output signal of a sensor represents the actual temperature.
This signal is measured several times a second. The value measured is a
"snap-shot" of the real temperature as it will be fluctuating.
With the help of this digital filter a stable and accurate reading can be
obtained while the filter level can be set to a desired value.
The filter principal is based on three input values: the filter level (01-99),
the last measured analog value and the last average value. The higher
the filter level, the longer the response time on a value change will be.
Filter value
Response time on step change of analog value. (Time in seconds).
