Operation on the transmitter

4.3.1 General
The SITRANS P pressure transmitter can also be set locally. The start of the scale and full scale can be
"set" or adjusted with three keys; other parameters can be set using the digital indicator. The keys are
accessible after unscrewing both screws and lifting up the protective cover.
Figure 4.2 Control elements of the SITRANS P transmitter
The transmitter is always delivered with a built-in digital indicator (full pushbutton operation possible). The
version of the cover (with or without viewing window is as ordered).
In transmitters with cover without viewing window the pushbuttons and functions are disabled ("LS" in
the digital indicator means: all functions disabled except start of scale and full scale, see Figure 4.3).

If the disabling is released for comfortable operation with the cover open, the function disabling should
be reset after completing the work (see chapter 4.3.3.7, page 31). This reinstates the as-delivered
condition and potential operating errors are avoided.
