5. Persediaan

5.1 Membongkar dan Pemeriksaan Awal

Carefully remove the balance from its packaging. Inspect all components for any signs of damage. If any damage is found, do not use the balance and contact customer support immediately.

5.2 Penempatan

Place the balance on a firm, level, and stable surface. Ensure the location is free from vibrations, drafts, direct sunlight, and rapid temperature fluctuations, which can affect measurement accuracy.

5.3 Leveling the Balance

The balance must be perfectly level for accurate readings. Use the adjustable feet at the bottom of the balance to center the bubble in the integrated level indicator (refer to Figure 4.4).

5.4 Sambungan Kuasa

Connect the provided power cord to the balance and a suitable power outlet (100-240V). Alternatively, the balance can be powered by a 9V battery for portable use.

5.5 Warm-up Time

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

6. Arahan Operasi

6.1 Hidupkan/Mati Kuasa

  • Tekan ke HIDUP/MATI button to turn the balance on.
  • Tekan dan tahan butang HIDUP/MATI button to turn the balance off.

6.2 Penimbangan Asas

To perform a basic weight measurement:

  1. Ensure the balance is level and has completed its warm-up.
  2. Tekan ke TARE / ZERO button to set the display to 0.000g.
  3. Carefully place the item to be weighed on the center of the weighing pan.
  4. Wait for the reading to stabilize. The stable weight will be displayed.

6.3 Fungsi Tara

The tare function allows you to subtract the weight of a container, so only the net weight of the contents is measured.

  1. Letakkan bekas kosong di atas kuali penimbang.
  2. Tekan ke TARE / ZERO button. The display will reset to 0.000g.
  3. Add the material to be weighed into the container. The display will show the net weight of the material.

6.4 Penukaran Unit

The balance supports multiple weighing units. To change the unit:

  • Tekan ke UNIT button repeatedly to cycle through available units: g (grams), ct (carats), oz (ounces), ozt (troy ounces), lb (pounds), gn (grains), t (metric tons), dwt (pennyweights), kg (kilograms), dr (drams), tlT (Taiwan Tael), N (Newtons), and % (percentagdan).
  • Unit yang dipilih akan dipaparkan pada skrin.

6.5 Parts Counting (PCS)

Fungsi ini membolehkan anda mengira sejumlah besar item yang sama mengikut berat.

  1. Place a known quantity of items (e.g., 10, 20, 50, 100, 150, 200, 250, 500) on the pan.
  2. Tekan ke PCS butang.
  3. Select the corresponding sample quantity using the UNIT butang.
  4. Tekan PCS again to confirm. The balance is now in counting mode.
  5. Add more items, and the display will show the total count.

6.6 Peratustage Menimbang

Peratusantage function is useful for formulation and quality control, allowing you to measure a sample's weight as a percentage dari berat rujukan.

  1. Letakkan rujukan sample atas kuali penimbang.
  2. Tekan ke UNIT button until '%' is displayed. The reference weight will be set as 100%.
  3. Keluarkan rujukan sample.
  4. Place subsequent samples on the pan. Their weight will be displayed as a percentage daripada berat rujukan.

6.7 Penentukuran

Regular calibration ensures the accuracy of your balance. It is recommended to calibrate the balance upon initial setup, after relocation, or if you suspect inaccurate readings.

  1. Ensure the weighing pan is empty and the balance is stable.
  2. Tekan dan tahan butang 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 (provided) onto the center of the weighing pan.
  5. Wait for the balance to automatically calibrate. Once complete, the display will show 'PASS' or return to normal weighing mode.
  6. Remove the calibration weight.
