Appears when the weight reading has settled and is stable.
Bars decrease as battery drains. When only the frame flashes, replace batteries soon.
If weight exceeds 100 kg / 220 lb, the screen shows "FULL" and the red LED flashes. Remove weight immediately to avoid damaging the platform and sensor.
If the weight on the platform doesn't change for 10 minutes, the scale shuts off automatically to save battery.
Runs automatically at startup — takes less than 2 seconds.
Works across the full 100 kg range — you can tare out a heavy tank and still read the net refrigerant weight accurately.
✅ Use the scale only within the specified temperature and humidity range
✅ Replace batteries before the display becomes unstable — a bad reading at the wrong time can throw off a charge
✅ Remove batteries if storing the scale for an extended period — leaking batteries can corrode the internals
❌ Do not use chemical solvents or corrosive liquids to clean the scale
❌ Do not disassemble the scale body or internal components — this will cause weighing errors
❌ Do not yank or stretch the spiral cable — this can damage the sensor and throw off accuracy
❌ Do not exceed 100 kg / 220 lb on the platform
Always tare the scale with the tank on it before opening valves — that way you're reading net refrigerant flow, not guessing from a starting weight.
