3. Konfigurazioa

Proper setup is crucial for accurate measurements.

1. Lekua: Place the balance on a stable, vibration-free surface, away from direct sunlight, air currents, and significant temperature changes.
2. Doikuntza horizontala: Use the adjustable leveling feet at the base of the scale to center the bubble in the built-in level indicator. This ensures the weighing pan is perfectly horizontal.
3. Muntaia: Carefully place the stainless steel weighing pan onto the center of the weighing platform. Ensure the glass draft shield is properly assembled around the weighing area.
4. Potentzia-konexioa: Connect the power adapter to the balance and plug it into an AC 100V-240V power outlet. Alternatively, the scale can be powered by 4x1.5V batteries (not included) for portable use.
5. Beroketa-denbora: After powering on, allow the balance to warm up for at least 30 minutes before making critical measurements. This stabilizes the internal components for optimal accuracy.

4.5 Data Output (RS232 & USB)

The lab scale is equipped with RS232 and USB ports for connecting to a computer or printer. It supports three printing modes: continuous print, key print, and command print.

For detailed instructions on configuring continuous output or key output settings, please refer to the video demonstration below.

5. Kalibrazioa

Calibration ensures the accuracy of your balance. It is recommended to recalibrate after moving the balance or before critical use.

5.1 Eskuzko Kalibrazioa

Eskuzko kalibrazioa egiteko:

1. Ensure the weighing pan is empty.
2. Eduki sakatuta TARE/CAL button until 'CAL' appears on the display.
3. The display will then show the required calibration weight (e.g., 500.000g).
4. Carefully place the specified calibration weight onto the center of the weighing pan.
5. Wait for the balance to stabilize and confirm the calibration. The display will return to 0.000g once complete.
6. Remove the calibration weight.

5.2 Standard and Linear Calibration

For detailed steps on performing standard and linear calibration, please refer to the video demonstration in Section 4.5.
