265Dx transmitter with measuring range of 10 mbar:
- Use a torque wrench to tighten the process flange screws, working on them alternately
and in a crosswise manner. Tightening torque: M
T = 10 Nm (1.0 kpm).
- Check the tightness of the connection:
- Apply a maximum pressure of 1.3 x PN (nominal pressure) to the 265Dx; pressure
should be applied to both sides of the measuring equipment at the same time.
- Apply a maximum pressure of 1.0 x PN (nominal pressure) to the 265Vx.
- Use the buttons on the control unit or, if available, an LCD display or graphical user
interface (DTM) to check the "lower range value" and "upper range value" as outlined in
the paragraph "Configuration".
