Combining 8 single-function calibrators, legacy 10–50 mA capabilities, and troubleshooting tools, PIE 850 helps diagnose hard-to-find, common loop control problems. Handheld instrument includes milliamp current calibrator, voltage calibrator, thermocouple calibrator, RTD resistance calibrator, frequency calibrator, pH simulator, continuity checker, and pressure calibrator. Also included, Loop diagnostic technology and LoopScope feature reveal all loop parameters in one glance.
