5. Opsætning

5.1 Indledende placering

1. Place the moisture analyzer on a stable, vibration-free, and level surface, away from direct sunlight, drafts, and heat sources.
2. Sørg for tilstrækkelig plads omkring enheden til ventilation.
3. Install the wind cover to minimize external air disturbances affecting measurement accuracy.
4. Place the triangle scale frame and a clean aluminum weighing pan onto the weighing platform.

5.2 Strømtilslutning

1. Connect the provided power cord to the analyzer's power input and then to a suitable electrical outlet (110V or 220V, 50Hz/60Hz).
2. Turn on the power switch, usually located at the rear or side of the unit.
3. Allow the instrument to warm up for at least 15-30 minutes for stable operation.

5.3 Kalibrering

Regular calibration ensures measurement accuracy. The GS110B includes a 100g calibration weight.

1. Access the calibration function via the touchscreen menu (refer to Figure 5.1 for menu navigation).
2. Follow the on-screen prompts to perform calibration using the 100g calibration weight.
3. Ensure the weighing pan is empty and clean before starting calibration.

6. Driftsprincipper

The GOYOJO GS110B Moisture Analyzer operates on the thermogravimetric principle. It uses a halogen lamp to rapidly heat the sample, causing moisture to evaporate. Simultaneously, precision sensors continuously monitor the sample's weight. As the moisture content decreases, the weight of the sample changes. The analyzer calculates the moisture content based on the initial and final weights, and the temperature profile. This method provides fast and accurate results, typically within minutes, making it an efficient alternative to traditional drying ovens.
