PIE 901 4-20mA Multifunction Calibrator

Overview

The PIE 901 is a compact field calibrator designed for technicians who need to troubleshoot, measure, and calibrate 4-20mA loop instruments and voltage-based devices. It combines milliamp sourcing and measurement, DC voltage generation and measurement, and optional pressure measurement in a portable package with a backlit color display for use in low-light plant environments.

Key Features

• Source 4-20mA signals with 0.001 mA resolution using digital potentiometer dial or preset settings
• Measure 0-24 mA loop current with greater accuracy than standard multimeters
• Automatic output stepping and ramping modes for quick calibration
• Patented loop diagnostic technology to detect ground faults and current leakage
• Source and measure DC voltage from -60 to +60 VDC with 0.001 V resolution
• Power 2-wire HART transmitters with internal 24V supply and 250Ω built-in resistor
• Simultaneous milliamp and pressure display when used with optional pressure modules
• Full color backlit display for visibility in dark areas
• Operates with rechargeable batteries or AA alkaline batteries

Applications

• Field calibration of 4-20mA transmitters and receivers
• Troubleshooting loop signal problems in process control systems
• Calibration of recorders, PLC inputs, and stroke valve actuators
• Testing of HART-enabled instruments and communicators
• Pressure gauge and transducer calibration with optional modules

Included Accessories

• Rubber boot for protection
• Four AA alkaline batteries
• Test leads with banana plugs and alligator clips (1 meter)
• Calibration certificate
• Hands-free carrying case
