REQ-009 — Output current readback accuracy ≤ ±0.1mA

The measured (readback) output current shall be accurate to within ±0.1mA of the true channel output current, with stable accuracy across the active current range (0–600mA).

Channel current set across 0–600mA at ≥10 points; readback compared against a calibrated reference ammeter; |I_readback − I_reference| ≤ 0.1mA at every point, repeatable across the range and stable over a 30-minute soak (25°C ambient).
