PIE 311PLUS Diagnostic RTD & Milliamp Calibrator

Overview

The PIE 311PLUS is a diagnostic RTD and milliamp calibrator combining two instruments in one. It provides troubleshooting tools for loop diagnostics, ground leak detection, and comprehensive calibration capabilities for RTD sensors and 4-20 mA loops.

Key Features

• Ground Leak Detection — patented technology to identify and resolve grounding faults before they cause failures
• Dual calibrator functionality — calibrates 12 RTD types and 0-24 mA milliamp loops simultaneously
• Direct temperature calibration — work in °C or °F without decade boxes or resistance tables
• RTD sensor measurement — automatically detects 2, 3, or 4-wire connections and measures sensors in degrees or ohms
• 4-20 mA loop testing — source, read, measure, and simulate two-wire transmitters
• HART transmitter support — built-in 250 Ω resistor for HART communicator hookups
• Automatic output stepping — 2, 3, 5, 11, or 21-step calibration with configurable step times
• Rugged design — rubber boot, low-profile switches, backlit display for field use

Applications

• Plant floor and field troubleshooting of temperature loops
