{ } Items in curved brackets are optional extras for additional price.
Functional test
Open pressure connections only after the system is without pressure!
Observe the ambient and working conditions outlined in section 7 „Technical
data".
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.
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.
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 9 „Troubleshooting“.

. Trouble shooting
Open pressure connections only after the system is without pressure!
WIKA pressure transmitters require no maintenance.
Have repairs performed by the manufacturer only.
Do not insert any pointed or hard objects into the pressure port for cleaning to prevent
damage to the diaphragm of the pressure connection.
Take precautions with regard to remaining media in removed pressure trans-
mitters. Remaining media in the pressure port may be hazardous or
toxic!
Remove the pressure transmitter from service and mark it to prevent it from
being used again accidentally, if it becomes damaged or unsafe for opera-
tion.
Have repairs performed by the manufacturer only.
