Functions "4mA" and "20mA" are used to define the measurement range for the flow rate, the input frequency or
the totalizer associated with the current on the 4-20 mA output.
P
1
and P
2
are the values associated with a current of 4 mA or 20 mA respectively: P
1
may be greater than P
2
: if
this is the case, the signal is inverted and range P
1
-P
2
corresponds to the range for the 20-4 mA current.

Flow rate, input frequency or totalizer chosen
Figure 40 : 4-20 mA current according to the chosen physical parameter or totalizer
PVAR: Choose a physical parameter (flow rate volume unit or input frequency) or a totalizer combined with
current output 1 or current output 2 respectively.
4mA: Choose the value of the physical parameter or the totalizer (previously selected) and the flow time unit,
combined with a current of 4 mA for each current output. See “Current output parameters”, next page.
20mA: Choose the value of the physical parameter or the totalizer (previously selected) and the flow time unit,
combined with a current of 20 mA for each current output. See “Current output parameters”, next page.
FILTER: choose the level of damping for the fluctuations of the current value for each current output. Three
damping levels are proposed: "slow", "fast" or "none".
The damping for the current outputs is similar to the damping of the display. See Figure 39.
DIAG MODE: choose to emit a current of 22 mA on the current output selected when an "error" event related
to diagnostics (see chap. 9.14.2 and ) is generated by the device or allow the current output to operate normally
(choose "none").
