Fluke Fluke-714B Temperature Calibrator, RSCAL

This temperature calibrator provides portable, single‑function measurement and simulation for thermocouples and millivolt signals in field and workshop settings. Battery powered and compact, it is intended for technicians in automation, electronics, electrical and mechanical trades who require precise temperature sourcing and mA loop checks while working at height or on the move.

• 0.010%+2μA accuracy delivers precise source and measurement control
• Measures and simulates 17 thermocouple types for broad compatibility
• 0.001mA resolution with 0–24mA range supports tight loop diagnostics
• Dual inputs and backlit display improve visibility and comparison tasks
• Configurable 0%/100% sourcing enables quick linearity and ramp tests
• Battery operation on AA cells ensures true portable use in the field

• Suitable for temperature transmitter calibration and commissioning
• Ideal for on‑site thermocouple verification and millivolt checks
• Used for loop checkout of 4–20mA control circuits during maintenance
• Can be used with portable probes for HVAC and industrial troubleshooting
• Used for traceable calibration workflows requiring UKAS‑grade performance

It meets IEC 61010‑1 safety requirements, has IP52 ingress protection, and is specified for operation from -10°C to 50°C with defined humidity limits for non‑condensing environments.

The device supports Pulsed transmitters and PLCs with Pulse widths down to 5 ms, allowing reliable sourcing and measurement with fast digital outputs.

It runs from four AA batteries (NEDA 1.5A/IEC LR6) and retains power‑down settings for quick restart of repeated procedures.

Units are supplied with a traceable calibration certificate and specifications available for both one‑year and two‑year intervals.

The handheld unit weighs 515 g, includes a magnetic hanging tool, and operates without mains power for convenient field deployment.
