Description
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
- Calibration of temperature transmitters and RTD instruments
- Current loop diagnostics and 4-20 mA device calibration
- Two-wire transmitter powering and output verification
Included Accessories
- 4 AA batteries
- Set of test leads
- Rubber boot
- Hands-free carrying case
- NIST traceable certificate of calibration
- 3-year repair/replacement warranty
