Pengaturan
1. Pembongkaran dan Penempatan
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. Perakitan
- 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.

4. Koneksi Daya
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.

Refer to the specific calibration procedure in the full manual for detailed steps. Generally, this involves pressing the KALI button and following on-screen prompts using the provided calibration weight.
5. Fungsi Penghitungan Keping
The balance includes a piece-counting function for counting multiple items of uniform weight. To use this feature:
- Tempatkan sejumlah angka yang diketahuiample pieces (e.g., 10, 20, 50, or 100) on the pan.
- Tekan tombol MENGATUR button and follow the instructions to input the sampkuantitas.
- Setelah sample is registered, remove it and place the bulk quantity of items on the pan. The display will show the total count.
