Fluke 5450A Resistance Calibrator 1.0 Ω - 100 MΩ

Resistance Calibrator 1.0 Ω - 100 MΩ

The Fluke 5450A Resistance Calibrator provides precision resistance outputs from 10 ohms to 100 megohms for calibrating digital multimeters. It supports four wire measurement configurations with defined accuracy and stability across multiple ranges. The instrument includes front panel control and an IEEE 488 interface for automated operation. It displays the selected resistance value and measurement error in percent or parts per million for the unit under test.
