If you were to make your own meter using normal standard components, you’d be lucky to be accurate with ☒0% (based on the values of resistors, capacitors, and any critical components). Often, the higher you go (in terms of input voltage or current) the less accuracy you have (components warming up causes value drifting, eg a resistor value increases). So while the internal electronics are rated at more than 500mA, the fuse is added for protection, but above 200mA your measurements could be 20% off. Meters become more expensive as they become more accurate, due to using better internal components.Memory mode stores Last Min and Max readings.
