8. Adjustment of zero point / span
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
equipment at your disposal (at least three times more accurate than the instrument
being tested).
Make sure wires are not cut or pinche
during disassembly and reassembly of the
connector.
Remove the female connector. Open the
pressure sensor by detaching the clam-
ping nut (see Fig. A ). Carefully remove
the male connector from the case.
Adjust the zero point (Z) (see Fig. B ) by
generating the lower limit of the pressure
range.
Adjust the span (S) by generating the
higher limit of the pressure range.
Check the zero point.
If the zero point is incorrect, repeat
procedure as required.
Reassemble the instrument carefully.
Make sure all sealings and o-rings are not
damaged and correctly installed to assure
the rated moisture ingress protection.
Recommended recalibration cycle:
half-yearly
