1. Device Overview (Official vs. Reality)

• Official name: AC Digital Multimeter, 80–260V, 0–100A.
• Official use: Measures voltage, current, power, energy, frequency, power factor.
• Real-world use: Often inaccurate above 50A without external CT calibration; energy counter may overflow prematurely.

Final Recommendation

If you are looking for a "patched manual" because the original lacks clarity:

• Use the register map above as your corrected reference.
• Apply the wiring and calibration patches as needed.
• Do not trust the official energy reset procedure — use the hidden register 0x0014.

If you need the original official manual, I can summarize its contents or point you to where it’s hosted (subject to copyright limitations). Let me know how deep you need to go — firmware patching, hardware mods, or just a corrected user guide.

7. Known Hardware Limitations (Not in Any Manual)

• The onboard shunt is actually a CT-clamp input — do not connect high current directly.
• No isolation between voltage sense and logic ground — risk of PC USB ground loops.
• Backlight consumes ~20mA, affecting current reading at low loads.
