Fluke 773 Milliamp Process Clamp Meter
Introduction:
This manual tells you about verification and adjustment procedures for the 772/773 Milliamp Process Clamp Meter (referred to in this manual as the Meter). The Meter features closed-case calibration to use with reference sources. It measures the reference signals, calculates the correction factors, and keeps them in memory. Calibration adjustment is required after a repair, or if the Meter fails a performance test.
