ove and retain all instruction manuals and performance certificates that are shipped with the product. These documents

Rem
provide import ant information on the product’s calibration, operation, safety precaut ions, recommended maintenance, re-calibration
requirements, repair service instructions and warranty information. Thes e documents are updated from time to time as changes to
the product occur and should be reviewed at receipt so that proper and safe installation can occur.

The Model 350 has been pre-set at t he factory for the required output and is referenced to absol ute zero (full vacuum). Once
factory set, the product should perform as indicated by the performance certif icate and product labeling. In all cases the zero and
span cannot be externally adjusted, hence any deviati on from t he factory setti ngs would indicate damage to t he sensor, el ectronics
(model dependent), or both. On sealed units, output will go positive with positive pressure applied to the pressure port. For
absolutes, the pressure port must have a full vacuum applied t o reach the absolute zero point. After the full vacuum is applied, the
unit will begin to read positive pressure changes as less and less of a vacuum is evident at the pressure port.
