Fluke 717 measures pressure and current simultaneously to check P/I transmitters, gauges and pressure switches. Separate models have upper ranges from 1 to 10,000 psi. Each internal sensor has its own range; one instrument does not cover the whole family. There is no built-in pump, so pressure comes from a suitable external source. The 24 V loop supply, Zero, Min/Max, Hold, Damp and switch test support field checks. Optional pressure modules are selected separately. Check media compatibility and overpressure limits for the exact model.
