  1. Adjust the probe to a suitable depth according to the type of installation.
  2. Tighten the clasp nut to finger tightness.
  3. Draw a line on the fitting screw and the clasp nut to mark their position.
  4. Tighten the nut a further 50 … 60º (1/6 turn) with a wrench. If you have a suitable torque wrench, tighten the nut to max 45 ±5 Nm (33 ±4 ft-lbs).

    Do not overtighten the clasp nut.

CAUTION

Take care not to damage the probe body. A damaged body makes the probe less tight and may prevent it from going through the clasp nut.

CAUTION

In pressurized processes it is essential to tighten the supporting nuts and screws very carefully to prevent loosening of the probe by the action of pressure.

When installed in a process with a pressure differing from normal atmospheric pressure, input the correct pressure into the pressure compensation setpoint parameter or register of the probe. This allows the probe to apply the appropriate pressure compensation into its measurement results.
