Ρύθμιση

1. Αποσυσκευασία και Τοποθέτηση

Carefully remove all components from the packaging. Place the balance on a sturdy, level, and vibration-free workbench, away from direct sunlight, heat sources, and strong air currents (e.g., air conditioning vents).

2. Συνέλευση

• Place the weighing pan onto the pan support in the center of the balance.
• Assemble the draft shield around the weighing pan. Ensure all panels are securely in place to protect against air disturbances.

3. Ισοπέδωση

The balance must be perfectly level for accurate measurements. Adjust the adjustable feet at the bottom of the balance until the bubble in the spirit level (located on the front or side of the balance) is centered.

4. Σύνδεση ρεύματος

Connect the UL-certified power cable to the 6V DC input port on the rear of the balance and then plug it into a suitable power outlet.

5. Warm-up Time

After connecting to power, allow the balance to warm up for at least 30 minutes before use. This stabilizes the internal components and ensures optimal accuracy.

4. Διαμέτρηση

Regular calibration ensures the accuracy of your balance. It is recommended to recalibrate if the balance has been moved or if accuracy is critical. Refer to the specific calibration procedure in the full manual for detailed steps. Generally, this involves pressing the CAL button and following on-screen prompts using the provided calibration weight.

5. Λειτουργία καταμέτρησης κομματιών

The balance includes a piece-counting function for counting multiple items of uniform weight. To use this feature:

• Place a known number of sample pieces (e.g., 10, 20, 50, or 100) on the pan.
• Πατήστε το ΣΕΙΡΑ button and follow the instructions to input the sample ποσότητα.
• Μόλις το sample is registered, remove it and place the bulk quantity of items on the pan. The display will show the total count.

The balance features an overload alarm function. If the weight on the pan exceeds the maximum capacity (110 g), an alarm will sound, and an error message may appear on the display. Immediately remove excess weight to prevent damage to the weighing sensor.

Συντήρηση

1. Καθάρισμα

Clean the balance regularly with a soft, damp cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the display or housing. Ensure no liquids enter the internal components.
