WARNING - POTENTIAL DAMAGE TO TRANSMITTER
In case of an HART gauge pressure transmitter with 1050 bar/15000 psi sensor range and 1/4" NPT process connection, please
always perform sensor low trimming to remove possible zero shift and prevent a serious decrease of the total performance in
terms of accuracy. Sensor low trim can be performed via LCD, DTM or handheld terminals.
