Meters are only as useful as the ranges and accuracy they provide. This group of attributes defines how instruments measure signals, how precise they are, and how results are displayed.
Average ranges and peak ranges show whether a meter captures short bursts or long-term exposures.
Line noise range quantifies electrical noise from wiring or appliances, while receiver sensitivity defines the weakest signals a meter can detect.
Accuracy ratings (such as ±8%) and refresh rates provide practical insight into how stable, fast, and reliable the readings are.
Clamp ranges (0–60A, 0–1200A) give context for current clamps measuring household and industrial loads.
By grouping these attributes, Safe and Sound provides a clear picture of how well each meter performs — from quick household checks to precise professional assessments.
