In an oxygen version model IS-11 is not available. In an oxygen version model IS-10 is only available in gauge pressure ranges
≥ 0.25 bar with media temperatures between -4 ... +140 °F / -20 ... +60 °C and using stainless steel or Elgiloy
{ } Items in curved brackets are optional extras for additional price.
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 transmitter is only used within the over

load threshold limit at all times!
When touching the pressure transmitter, keep in mind that the surfaces of
the instrument components might get hot during operation.

8. Adjustment of zero point / span

8. Adjustment of zero point / span (only for pressure transmitter 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).
Make sure wires are not cut or pinche

during disassembly and reassembly of
the connector.
Remove the female connector. Open

the pressure transmitter by detaching
the clamping 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 protec-
tion.
Recommended recalibration cycle: 1 year
