3.1 Mechanical Installation
Before starting operation, check the process connection carefully for leaks under pressure.
Use gaskets, if required, that are suitable for the process connection and resistant to the
media.
3.2 Electrical Connection
Complete the mechanical installation before you connect the device electrically.
Set up all electrical connections while the voltage supply is switched off.

Operation
During operation, take care that the device remains within its intended pressure and tem-
perature ranges. No other monitoring is necessary.
Permissible media temperature:
-
40…100 °C
Permissible ambient temperature:
-
40…70 °C
4.1 Zero-point setting
Set the zero-point of the measuring device and the angle-of-rotation sensor separately.
4.1.1
Zero-point correction
Zero point deviations can occur due to the
mounting, the installation position or due to
the type and duration of use. Measuring de-
vices with micro control position pointers
can be corrected in a depressurised state
by means of the adjusting screw on the
pointer hub (see figure 1).
You can find further information about zero-
adjustment of pressure gauge with micro
adjustment pointer in the document TA_029
on www.labom.com.
