- Col·locació: Place the balance on a stable, level surface away from vibrations, drafts, direct sunlight, and extreme temperature fluctuations.
- Resistència química: The balance is constructed with chemical-resistant polybutylene terephthalate, stainless steel, and glass. However, avoid prolonged exposure to harsh chemicals and clean spills immediately.
- Protecció de sobrecàrrega: Do not exceed the maximum weighing capacity of 3200 g.
- Neteja: Desconnecteu l'alimentació abans de netejar. Feu servir un drap suau i sec.amp cloth and mild detergent. Do not use abrasive cleaners or immerse the balance in water.
3. Configuració
3.1 Desembalatge
Carefully remove the balance and all accessories from the packaging. Retain the original packaging for future transport or storage.
3.2 Col·locació
Select a location that is free from drafts, vibrations, and rapid temperature changes. Ensure the surface is firm and level. The balance dimensions are approximately 7 inches (pan length) by 7 inches (pan width).
3.3 Connexió d'alimentació
Connect the provided power adapter to the balance and then to a suitable electrical outlet (100 to 240 VAC, 50/60 Hz).
3.4 Anivellació
Adjust the leveling feet located at the base of the balance until the air bubble in the spirit level (usually located near the display) is centered. This ensures accurate weighing results.
3.5 Initial Calibration (isoCAL)
The Entris II features isoCAL internal calibration. Upon initial setup or after relocation, it is recommended to perform an internal calibration. Refer to the on-screen prompts or the balance's menu for initiating this process. This ensures optimal accuracy.
