1. Remove all weight → click TARE on main page
2. Place known weight → enter it below → click CALIBRATE Important after NAU7802 upgrade: new calibration factor will be very small (usually 0.0001–0.01 range) — this is normal!
Used to convert drum RPM to engine RPM in fixed-ratio setups (e.g. chain/belt + gearbox). Ignored in CVT mode.
How many times the hall sensor triggers per full crankshaft revolution.
• 1 = single magnet/tooth (most common)
• 0.5 = ignition coil signal (fires once every 2 crank revs, common on 4-stroke)
• Other: 2, 4, 6, 8, 10 (max 10)
Higher for quick 2-stroke spool-up (0.5–0.8), lower for smooth 4-stroke (0.2–0.3)
Similar to engine, for the drum sensor.
