Fluke Loop Calibrator, ±0.01% Accuracy, 1 μA Resolution - Fluke-709


This loop calibrator is a handheld instrument for sourcing, simulating and measuring 4–20 mA process loops, including HART-enabled devices for on-site diagnostics. It is designed for technicians working in automation, electronics and mechanical maintenance who need a compact, portable tool to power loops, verify transmitter outputs and capture field data.

Features & Benefits


• ±0.01% accuracy for precise current verification and calibration
• 1 μA resolution enabling fine adjustment and tight tolerance checks
• Built-in 24V loop power for single-wire mA measurements
• Rechargeable NiMH power option supporting short-term field use
• Selectable 250 Ω resistor to Interface with HART transmitters
• Logging capacity of 9,800 records for extended diagnostic traces

Applications


• Suitable for commissioning and tuning 4–20 mA transmitters in plants
• Ideal for troubleshooting HART-enabled field instruments on site
• Used for validating loop integrity during preventive maintenance
• Can be used for recording process variables for control loop optimisation

What communications capability assists with HART device troubleshooting?


It includes a HART modem that supports common universal and common practice commands to read tags, sensor PVs, long tags and perform DAC trims and zero/gain adjustments.

How is logged data exported for analysis?


Recorded HART configurations and mA measurements can be uploaded via dedicated software to produce .csv or .txt files for further examination.

What environmental range allows safe operation in industrial settings?


The instrument operates between −10 °C and +55 °C with 10–95% non‑condensing humidity for typical plant conditions.

Which protection features prevent damage from wiring errors?


The unit provides over-voltage protection to 240 VAC and overload current protection at approximately 28 mA DC to reduce risk from fault conditions.

Supplied with

AC72-1 alligator clips (2), TL75 test leads, soft case, 6 AAA batteries (installed), product manual, quick reference guide, safety information
