FieldSense technology: simultaneously measures AC voltage and AC current without physical contact with the conductor.
Power quality indicator: The meter automatically detects power quality problems. When measuring via FieldSense, the 378 indicates whether there is poor power factor (Power Factor), THD (total harmonic distortion) or problems in the source or load.
3-phase voltage and current tests: Calculate the full set of phase-to-phase values in three easy steps.
iFlex flexible current clamp: Includes flexible current clamp for measurements up to 2500 A in very tight spaces.
Visual display: The display turns green when a stable measurement is achieved and turns orange when the Power Quality indicator detects a problem.
Safety: Certified for CAT IV 600 V and CAT III 1000 V.
