Model No :
Fluke 712B
Part Code :
4387869

Overview

Fluke 712B RTD is a handheld Calibrator, 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 whiles sourcing a temperature signal. It is 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.

Features
- Highly accurate, full-featured , easy-to-use single function RTD temperature calibrator
- Measures and simulates 13 different RTD types and resistance
- Measures 4 to 20 mA signals while simultaneously sourcing a temperature signal
- Features configurable 0% and 100% source settings for quick 25% linearity checks
- Dual inputs and backlit display for easy interpretation of measurements
- Remembers power down settings to easily restart tests when powered up

Major Applications
- Simulate RTDs
- Calibrate and Test RTDs with Dry-Well

Technical Specifications
- DC mA Measurement: Resolution 0-24 mA; Range 0.001 mA
Accuracy (% of reading + counts) 0.010% + 2 µA
- Temperature coefficient: ± (0.002% of reading + 0.002% of range) /°C ( < 18°C or >28°C)
- Ohms Measurement (Ohms range): 0.00 O to 4000.00 O ; Accuracy: 0.015% + 0.05 O
- Ohms Source (Ohms range): 1.0 O to 4000.0 O (Excitation current from measurement device 0.1 mA to 0.5 mA)
- Temprature RTD: 13types of RTD's ; Resolution: 0.1°C
- 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
