Fluke 771 Milliamp Process Clamp Meter
Introduction:
This manual provides the complete verification and adjustment procedure for the 771 Milliamp Process Clamp Meter (referred to in this manual as the Meter). The Meter allows closed-case calibration using reference sources. It measures the reference signals, calculates the correction factors, and stores them in memory. The instrument should be calibrated after repair, or if it fails a performance test.
