Adjustment Of Zero Point/Span - Tecsis PEX11 Operating Instructions Manual

7. Starting, operation / 8. Adjustment of zero point / span
When designing your plant, take into account that the stated values (e.g.burst pressure,
over pressure safety) apply depending on the material, thread and sealing element used.
Functional test
The output signal must be proportional to the pressure. If not, this might point to a
damage of the diaphragm. In that case refer to chapter 10 „Troubleshooting".
Open pressure connections only after the system is without pressure!
„
Observe the ambient and working conditions outlined in section 7
„
„Technical data.
Warning
Please make sure that the pressure sensor is only used within the over load
„
threshold limit at all times!
When touching the pressure sensor, keep in mind that the surfaces of the
instrument components might get hot during operation.
Caution
8. Adjustment of zero point / span (only for pressure sensor with clamping nut)
We do not recommend to adjust the span potentiometer. It is used for adjustment ex
factory and should not be adjusted by you unless you have adequate calibration equip-
ment at your disposal (at least three times more accurate than the instrument being
tested).
