MF-P is a pressure transmitter designed for mea­suring of low positive, negative and differential pressure.

MF-P is designed for wall mounting. Remove the cover and mount the casing using max 0 4 screws in a suitable location. Drill pattern can be found on the backside of the enclosure.

Pressure connections should be made with Micatrone mounting kits for safe and tight function. Connect the measurement outputs with HT-plastic tube 8/6 mm.

□ Connect positive pressure to [+] connection.

□ Connect negative pressure to [-] connection.

NOTE! Leave unused connections open to the at­mosphere.

For differential pressure measurement, ensure that the highest absolute pressure is connected to the [+] connection. If the transmitter has a pressure range with zero-crossing (i.e -50...50 Pa) the high pressure connection [+] is connected to the mea­suring area and the low pressure connection [-] is connected to the reference area.

Switch on the voltage and wait at least 60 sec. Set the manifold valve in position calibration (if there is no valve, loosen the pressure tubes from

theMF-P).Removethecovertoaccessthead-justment keys on the main circuit board. Press down the "zero-setting"-button until the LED turns off. Release the button and the zero-setting is finished.

The Volt and mA output signal has different termi­nals. Check that the correct output is connected. Place the miniature switch no 3 in position "OFF" for volt signal (factory setting) or in position "ON" for mA-signal.

The MF-P offers a possibility to set different damping (time constant). At delivery the damping is set to 1,50 seconds damping. Setting is ad­justed with the miniature switch contacts no 4 and 5 (the switch is situated on the bottom left edge of the main circuit board, see figure).

Place the miniature switch no 1 in position "OFF" for full measuring range (100%) or in position "ON" for half measuring range (50%). NOTE! The accuracy is always for the full range.
