CONSTANT PRESSURE OPERATION
• Configure the micro switch DIP 1 of SW1 to obtain an output signal (0-10V).
• Configure the SW1 switches as indicated in the table below:

DIP 3
DIP 2
DIP 2
• Set the pressure range: Press the "OK" button and move to the required range using
buttons " " and " " . Finally press "OK" again to save the configuration. The pressure ran-
ges which may be selected are as follow: -50...+50 Pa; 0...+100 Pa; 0...+150 Pa; 0...+300 Pa;
0...+500 Pa; 0...+1000 Pa; 0...+1600 Pa; 0...+2500 Pa.
CONSTANT FLOW OPERATION
Only available with the TDP-D model.
In this mode of operation the pressure transmitter converts the pressure differential (ΔP)
to a flow (qv) based on the following equation:
• Place the transmitter's output signal type jumper (mA/V) in the voltage position (factory
setting).
• Configure the SW1 in airflow mode.
• Set the flow range and the parameter k: Press the "OK" button to access the airflow
range selection. Press again to access the individual digits of the parameter k, one by one,
with the option of selecting or not selecting a digit after the decimal point. Using buttons "
" y " " you can set the required values. Finally press "OK" to save the configuration and
exit the settings menu. The flow ranges which may be selected are as follow: 100 m
