Signal terminal is put into the electrical box, please take down the cover before connecting wire. The power is connected by the
signal wire, there is no need to connect other wire.
Signal wire adopts twisted pair. We recommend the shielded wire in the situation with serious electromagnetic interference and
please properly connect the wire to the ground .Don't put the signal cables into a metal tube with other power cables or put them
in the same slot,and decorate the wire far away from strong electric facilities.
1.Range Setting
The setting supports Range Zoom without pressure sources. IU-L represents 4mA, IU-H represents 20mA.
2. Amplification Factor
Changing Amplification Factor could change the value shows on the screen. After setting this value, the number shows= Amplification
Factor*/Actual measuring value
3. Null point Span
Supporting null point span without pressure sources. After setting this value, the number shows= Amplification Factor*/Actual measuring
value+null point span value
4. Filter factor
To prevent display value change from pressure fluctuation. Optional value:0-5. The higher this value is, the more stable and hysteretic the
display value is. (Filter factor would not influence current output)
