6. Commissioning

Before commissioning the device, check that it has been properly installed, and
make sure that it does not show any visible defects.
The device may by commissioned only by appropriately qualified and trained
personnel who have read and understood the user manual.
The device may only be operated within its specifications! (Compare the technical
data in the data sheet)
The instantaneously present output signal can be checked without breaking the current
loop by using a mA ammeter. This is done by connecting a mA ammeter to the "TEST"
and "-" electrical connector terminals and measuring the output signal present.

- / symbol
This symbol on the display indicates that the output signal has a linear
characteristic.
√ symbol
-
This symbol on the display indicates that the output signal has a square root char-
acteristic.
- symbol
This symbol shows when the signal has transgressed its upper or lower limits.
A bar graph is included on the display; this shows the acting pressure as a percentage of
the measuring range. The display indicates the measured value as well as allowing
configuration of the individual parameters using menus. The individual functions can be
set using two push buttons (accessible from the top). The device can be configured in situ
without opening the display and control module. In order to do so, the metal plate (on top
of the device) must be rotated to the rear after undoing the left screw. From left to right,
the two buttons are assigned to: Z, S.
