your application data sheet. You will access this data via the display (if ordered) or the Smart Interface Program (SIP) if connected
and installed on your computer. The meter will scroll through three screens: flow and temperature, pressure (if ordered), and
totalizer. See Chapter 3: Operating & Programming in your Instruction Manual.
4. Connect the analog outputs (if you are going to use them). The meter comes with three non-isolated outputs for
flow, temperature, and pressure.
