They are part of the delivery or can be downloaded under www.vega.com, "Instrumentsearch (serial number)" as well as in the download area.10.2 Calculation of the total deviationThe total deviation of a pressure transmitter indicates the maximum measurement error to be ex-pected in practice. It is also called maximum practical deviation or operational error.13) Galvanic separation between electronics and metal housing parts14) Protection rating IP 66/IP 68 (0.2 bar) only in conjunction with absolute pressure.15) When used with fulfilled housing protection.
