The P29 has an internal overpressure safeguard that protects the precision pressure
measurement capsule from damage. (Overload range: 200 x [max. 600 kPa])
7 Display (optional)
The measured values and the menu are shown on the display. The top line is the information
line. This line displays the type of measured value or the status of a zero-point calibration.
The measurement value will be displayed on the central line. If the permitted measuring
range is exceeded or not reached, the figures are replaced by corresponding arrows. The
bottom line displays the unit, with the first two digits showing the status of the two warning
messages.

If the P29 includes a display, you can use the menu to adjust various settings. Press the
Menu key to bring up the menu.

always shows the current sub-menu item or value to be changed. The bottom line displays
units or other help texts.
