Instruccions de funcionament
The Truma LevelCheck provides a simple and quick way to determine the gas level in your cylinder.
Procediment de mesura
- Ensure the gas cylinder is upright and stable.
- Hold the Truma LevelCheck horizontally against the side of the gas cylinder. It is crucial to hold the device at a 90-degree angle to the cylinder surface for accurate readings.
- Press the measurement head firmly against the cylinder wall. The device will automatically activate and perform a measurement.
- Observe the LED indicator:
- Llum verda: Indicates that there is gas present at the point of measurement.
- Llum vermella: Indicates that there is no gas present at the point of measurement.
- Move the device up or down the cylinder to find the transition point where the light changes from green to red. This point indicates the current gas level.
- The device automatically switches off after a few seconds of inactivity to conserve battery life.
