York Instrument CEP6000 Portable Multifunction Calibrator

Overview

The York Instrument CEP6000 Portable Multifunction Calibrator is an engineered-for-precision field and benchtop calibration solution designed to meet the rigorous traceability and functional requirements of industrial process control, metrology laboratories, and accredited calibration service providers. Built upon a dual-channel, galvanically isolated architecture, the CEP6000 performs simultaneous source-and-measure operations—enabling full loop verification of pressure transmitters, temperature transmitters (including HART-enabled devices), and analog I/O modules without external switching or auxiliary equipment. Its core measurement principle relies on high-stability, low-drift analog signal synthesis and digitization, calibrated against NIST-traceable standards and validated per ISO/IEC 17025–compliant procedures. With an accuracy of ±0.015 % of reading across key electrical and thermoelectric parameters, the CEP6000 bridges the performance gap between handheld field tools and stationary calibration systems—delivering laboratory-grade confidence in a rugged, battery-operated form factor.

Key Features

• Dual isolated mA/V input channels enabling concurrent simulation and measurement—critical for live-loop transmitter calibration under power
• Comprehensive thermocouple support: 13 standard types (J, K, T, E, R, S, B, N, C, D, G, L, U) with cold-junction compensation and user-defined reference junction options
• RTD emulation and measurement: Supports 13 RTD curves (Pt100, Pt1000, Ni120, Cu10, etc.) with programmable Callendar-Van Dusen coefficients and 4-wire/3-wire/2-wire configuration
• Integrated 250 Ω HART termination resistor and 24 V DC loop power supply (fuseless, current-limited)—fully compatible with smart transmitters and PLC analog inputs
• Modular pressure calibration via standardized DIN 16270 or ISO 10876-compatible external pressure modules (not included)
• Full-spectrum electrical signal generation and readback: 0–24 mA, 0–10 V, 0–100 kHz frequency, pulse train output, and 0–4000 Ω resistance
• Backlit graphical LCD with menu-driven navigation, numeric keypad, and three user-programmable soft keys for rapid access to frequently used functions
• Ruggedized housing with shock-absorbing rubber feet, IP54-rated enclosure, and MIL-STD-810G compliant drop resistance (1 m onto concrete)

Sample Compatibility & Compliance

The CEP6000 is validated for use with industrial pressure transmitters (4–20 mA, 0–5 V, 0–10 V outputs), thermocouple-based temperature sensors (Type K, J, S, etc.), platinum RTDs (Pt100 Class A/B per IEC 60751), and HART v5/v6/v7 devices. It supports calibration workflows aligned with ASTM E2877 (temperature sensor calibration), ISO 5167 (differential pressure instrument verification), and IEC 61511 (functional safety instrument calibration). All factory calibrations are documented with NIST-traceable certificates; optional on-site recalibration services comply with ISO/IEC 17025 requirements for accredited laboratories. The device meets EMC Directive 2014/30/EU and Low Voltage Directive 2014/35/EU, and its firmware architecture supports audit trails required under FDA 21 CFR Part 11 when paired with York’s optional calibration management software.

Software & Data Management

The CEP6000 features a full ASCII command set over RS-232 serial interface (DB9 connector), enabling integration into automated calibration systems, LIMS, or custom SCADA environments. Optional YorkCalSuite™ software provides protocol-driven calibration record generation—including as-found/as-left data, tolerance evaluation, uncertainty budgeting (per GUM), and PDF report export compliant with ISO 17025 Annex A. All internal logs retain timestamps, operator ID, and environmental conditions (ambient temperature/humidity if connected to optional external probes). Firmware updates are performed via secure USB-to-serial adapter; version history and digital signatures ensure integrity and regulatory traceability.

Applications

• Field verification and adjustment of pressure transmitters in oil & gas upstream metering skids and refinery control loops
• Thermocouple and RTD loop checks during pharmaceutical clean-in-place (CIP) and sterilize-in-place (SIP) system validation
• Factory acceptance testing (FAT) of packaged control panels with integrated analog I/O
• Accredited calibration lab execution of ISO/IEC 17025 scope items for temperature and pressure instrumentation
• QA/QC audits of HVAC-BAS controllers and building automation sensors in commercial infrastructure projects
• Training and competency assessment for instrument technicians under ISA/IEC 62443 cybersecurity-aware maintenance protocols

FAQ

Does the CEP6000 include built-in pressure measurement capability?
No—the CEP6000 requires external, separately purchased pressure modules for pressure calibration. It provides the interface, power, and signal conditioning for industry-standard modules compliant with DIN 16270.
Can the CEP6000 perform automatic calibration sequences?
Yes—when connected to YorkCalSuite™ software, it executes fully automated multi-point calibration routines with pass/fail logic, auto-adjustment (where supported by device firmware), and electronic signature capture.
Is the 24 V loop supply current-limited and short-circuit protected?
Yes—the 24 V output is electronically current-limited to 30 mA and automatically resets after short-circuit removal, eliminating fuse replacement requirements.
What RTD coefficient standards does the CEP6000 support?
It includes preloaded coefficients per IEC 60751 (Pt100/Pt1000), ASTM E1137 (Pt100), and JIS C 1604 (Ni120), plus user-definable Callendar-Van Dusen parameters for legacy or proprietary sensors.
How is traceability maintained during field use?
Each unit ships with a NIST-traceable calibration certificate; users may extend traceability via periodic recalibration at York-authorized centers or ISO/IEC 17025-accredited labs using York’s documented calibration procedures.
