NOTES. For a transducer with several measurement ranges, after specifying the code of the measurement range put the letter "П" (tunable).

Designation of technical specification - ТЖИУ.406233.001TU.

When the manufacturer releases transducer with multiple measuring ranges, it is configured on the upper measurement limit selected according to the Customer's order from the values shown in the table below:
