●
Before switching on the balance, wait until all parts are at room temperature (+5 to 40°C). The humidity must be between 10% and 80% non-condens ing.
●
The power plug must be accessible at all times.
●
Firm, horizontal and vibration-free location.
●
Avoid direct sunlight.
●
No excessive temperature fluctuations.
●
No strong drafts.
