7.1.3. Analog output

Setting options
Connected to terminals 4 and 5 is a programmable current output. It is an active current output, galvanically
isolated from other meter parts. The maximum output load is 1,000Ω. Depending on the liquid-flow
characteristics, the output can be used in four different modes of operation (see graphics below) and in two
selectable measurement ranges.
When the flowmeter is used for measurement of flow in both directions (bi-directional measurement), we
recommend to use current output mode |Q| and use one of the binary outputs (OUT1, OUT2 or relay output)
for indicating the flow direction.
Please contact the producer if is necessary to use mode –Q .. +Q and get information about the flow rate
and direction of flow at the same time (when using –Q .. +Q mode, there is no error indication for exceeding
analog range in negative flow direction).
The two-line display unit will always show two of the items from the following menu. Use the
to browse downwards and upwards through the menu items.

The current output setting consists of defining flow rate Q
key, and increase/decrease the Q
setting by pressing the
preferable the key. This action will take you back to the main configuration menu, item "Analog output".
In the "Fixed current" mode, the output current can be set within the range of 0 to 20 mA. This mode is used
for meter servicing purposes.

Move the cursor using the
the desired current value and confirm the setting by pressing the
Entered Press Any Key". Press any key, preferably the
menu, item "Analog Output". At the same time, the defined current will start to flow through the output circuit.
