TUNE-MIN
86
The (0)4mA or 0V value can be tuned precisely with this setting. The initial minimum
analog output value is (0)4mA or 0V. However, this value might differ slightly due to
ambient influences such as temperature for example.
Before tuning the signal, make sure that the analog signal is idle (not used) for
any application!
After pressing PROG, the current will be about 4mA (0mA or 0V). The current can be
increased / decreased with the arrow keys and is directly active. Press ENTER to
store the new value.
If required, you can program the analog output 'up-side-down'. The (0)4mA or 0V
represents the maximum flow rate and the 20mA or 10V represents the minimum
flow rate.
TUNE-MAX
87
The 20mA or 10V value can be tuned precisely with this setting. The initial maximum
analog output value is 20mA or 10V However, this value might differ slightly due to
ambient influences such as temperature for example.
Before tuning the signal, make sure that the analog signal is idle (not used) for
any application!
After pressing PROG, the current will be about 20mA or 10V. The current can be

If required, you can program the analog output 'up-side-down'. The (0)4mA or 0V
represents the maximum flow rate and the 20mA or 10V represents the minimum
flow rate.
FILTER
88
This setting is used to stabilize the output signal. With the help of this digital filter a
more stable but less actual representation of the flow rate can be obtained.
The filter principal is based on three input values: the filter level (01-99), the last
calculated flow rate and the last average value. The higher the filter level, the longer
the response time on a value change will be.

3.1.10 EXPLANATION OF SETUP-MENU 9 - PULSE
Two transistor or mechanic relay outputs are available as scaled pulse output according to the total.
MODE
91
The unit has three scaled pulse output modes. This functionality drives two pulse
outputs which, depending on the mode, can be used as follows:
not negative
On pulse output R1 a pulse will be sent when the total has increased with the set
quantity (SETUP 94). On pulse output R2 the sign of the flow rate will be send
(positive=0, negative=1).
separated
On pulse output R1 a pulse will be sent when the total has increased with the set
quantity (SETUP 94). On pulse output R2 a pulse will be sent when the total has
decreased with the set quantity (SETUP 94).
signed
On pulse output R1 a pulse will be send when the total has increased or
decreased with the set quantity (SETUP 94). Pulse output R2 will send a 0 for
increase or 1 for decrease.
