    Product overview: Fluke 712B RTD Calibrators

    Fluke 712B RTD Calibrator provides highly accurate, easy-to-use, single-function RTD temperature calibration

    Fluke 712B RTD Calibrator is a handheld, battery-operated instrument that measures and sources a variety of RTD types and resistances. It also includes an isolated channel to measure 4-20 mA while sourcing a temperature signal. It offers configurable 0% and 100% source settings for quick 25% linearity checks. It also provides linear ramp and 25% step auto ramp functionality based on 0% and 100% settings.

    Add to that dual inputs, an easy-to-view backlit display, plus the ability to memorize settings at power down for easy restart make the 712B the ideal test tool for temperature calibration professionals who want a highly accurate, easy-to-use, single-function RTD temperature calibrator.

    Other useful features:

    • Dual inputs and backlit display for easy interpretation of measurements
    • Remembers power-down settings to easily restart tests when powered up
    • Provides linear ramp and 25% step auto ramp based on 0% and 100% settings
    • Provides one-year and two-year specifications and traceable certification of calibration

1. Sensor inaccuracies not included.
2. Resolution: 0.1°C.
3. Read accuracy is based on 4-wire input. For 3-wire RTD measurements, assuming all three RTD leads are matched, add 1.0°C (Pt10 and Cu10), 0.6°C (Pt50 and Cu50), 0.4°C (Other RTD types) to the specifications.
4. Source Accuracy in source mode is based on 0.5 mA~3 mA (1.00 Ω~400.00 Ω), 0.05 mA~0.8 mA (400.0 Ω~1500.0 Ω), 0.05 mA~0.4 mA (1500.0 Ω ~4000.0 Ω), excitation current (0.25 mA for Pt1000 range).
5. Temperature Coefficient: ±0.05°C /°C for measure, ±0.05°C /°C (< 18°C or > 28°C) for source.
6. Supports pulsed transmitters and PLCs with pulse times as short as 5 ms.
