Near zero, only the BT270 resolves the pass lines. Published DC accuracy at ~0 A: Fluke 393 FC ±0.5 A (2% + 5 digits × 0.1 A, with ZERO), Seaward clamp ±0.2 A, BT270 ±5 mA (2% + 5 digits × 1 mA). The 125 mA and 40 mA lines sit inside the Fluke and Seaward error bands, which is why 2c (BT270) is the authoritative clamp and [32]–[34] record each meter’s zero.
