2 Fluke Corporation Fluke 71XB Temperature Calibrators
Ohms measurement (Fluke 712B)
Ohms range Accuracy
(% of reading +counts)
0.00 Ω to 400.00 Ω 0.015 % + 0.05 Ω
400.0 Ω to 4000.0 Ω 0.015 % + 0.5 Ω
Note: Read accuracy is based on 4-wire input. For 3-wire ohm measurements,
assuming all three leads are matched, add 0.05 Ω (0.00 Ω~400.00 Ω),
0.2 Ω (400.0 Ω~4000.0 Ω) to the specifications.
