The transmitters KPT can be installed in a connection point of the under pressure pipe.

It is recommended that the combination of a closing valve to facilitate the operations of mechanical installation or maintenance.

The driof the Zero caused by the installation position can be easily eliminated by the calibration trimmer Zero.

If you want to calibrate the Zero or Span unscrew the top of the transmitter body.

3) Unscrew the plastic ring nut, the male connector must not be rotated

to avoid damage to internal connections.

4) Carefully lithe male connector, be careful not to damage the internal

connection wires.

5) Tighten the inside screw.
