6. Commissioning, operation
By pressing button 1 briefly, the settings are saved. A successful 'Save' is signalled by
■
the display switching off briefly.
Select unit
Using buttons 2 and 3, select the required unit.
If a unit is skipped during the selection, display in these units is not possible.
Input the Zero Offset (offset)
The zero offset enables an adjustment of the display value shown on the display. Through
the adjustment of the display value, the matching of the unit to specific applications is
possible.
The value input is subtracted from the measured value, i.e. the characteristic curve is
shifted, in parallel, to the zero point.
The zero point offset has no influence on the analogue output signal from
the LED attachable indicator.
Indication
Simultaneously press and hold buttons 1 and 2 for five seconds. The display changes
■
to "OFFS" (offset).
Using buttons 2 and 3, set the required zero point offset (permissible range ±10 % of
■
the indication range).
Confirm the zero point offset using button 1. The display reverts to "OFFS".
■
By briefly pressing button 1, the display value will be shown once more.

The LED attachable indicator for pressure transmitters with voltage outputs are factory
preset with the output signals 0.1 ... 5.1 V or 0.1 ... 10.1 V. To operate the LED attachable
indicator with pressure transmitters with 0 ... 5 V or 0 ... 10 V output signals, an appropri-
ate zero point adjustment should be carried out.
