oftheswitchshouldbeperformedinaccordancewithallapplicablenational,state,andlocalcodes.

Material Compatibility:The enclosure is made of Polycarbonate (PC).The transducer is made of

PolyvinylideneFluoride(PVDF).Make surethatthemodel,whichyouhaveselected,ischemicallycompatible

guidelines to reduce any possible electrostatic charge build‐up on the technician’s body and the electronic

part.

1. Always touch a known good ground source before handling the

part. This should be repeated while

handling the part and more frequentlyafter sitting down from a  standing position, sliding across the

seatorwalkingadistance.

2. Avoidtouchingelectricalterminalsofthepartunlessmakingconnections.

3. DONOTopentheunitcoveruntilitistimetocalibrate.
