Controlled conditions

Record the exact model, serial number, firmware, sample source, and test date before any measurement.
Log ambient temperature, humidity, elevation, wind, surface, and background sound for every test block.
Record instrument model, range, accuracy, and most recent calibration or verification date.
Repeat timing, starting, and sound measurements three times when conditions allow; publish every valid run.

Safety gate

Operate fuel-burning equipment outdoors only, far from occupied structures, openings, and ignition hazards, with working carbon-monoxide monitoring for personnel.

Testing is for qualified personnel using correctly rated load equipment and the manufacturer’s required grounding, bonding, clearance, and protective-device instructions.

Never connect a generator directly to building wiring or bypass overload, temperature, battery, GFCI, or carbon-monoxide shutdown protection.

Stop a run for unstable voltage or frequency, overheating, fuel or electrolyte leakage, abnormal sound, damaged wiring, or any manufacturer fault indication.

Badge rule: this product receives no “FMG Tested” label or score benefit until a real unit, instruments, conditions, valid runs, raw records, and limitations are documented under the public protocol.
