5. Postavljanje

5.1 Raspakiranje i početni pregled

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 Postavljanje

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 Izravnavanje ravnoteže

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 Priključak za napajanje

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 Vrijeme zagrijavanja

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. Upute za rad

6.1 Uključivanje/isključivanje

  • Pritisnite tipku UKLJUČENO/ISKLJUČENO button to turn the balance on.
  • Pritisnite i držite UKLJUČENO/ISKLJUČENO button to turn the balance off.

6.2 Osnovno vaganje

To perform a basic weight measurement:

  1. Ensure the balance is level and has completed its warm-up.
  2. Pritisnite tipku TARA/NULA button to set the display to 0.000g.
  3. Pažljivo stavite predmet koji se važe na sredinu mjerne ploče.
  4. Wait for the reading to stabilize. The stable weight will be displayed.

6.3 Funkcija tare

Funkcija tare omogućuje vam oduzimanje težine posude, tako da se mjeri samo neto težina sadržaja.

  1. Stavite praznu posudu na posudu za vaganje.
  2. Pritisnite tipku TARA/NULA button. The display will reset to 0.000g.
  3. U posudu dodajte materijal koji treba vagati. Na zaslonu će se prikazati neto težina materijala.

6.4 Pretvorba jedinica

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

  • Pritisnite tipku JEDINICA 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 % (percentagi).
  • The selected unit will be displayed on the screen.

6.5 Parts Counting (PCS)

Ova funkcija vam omogućuje brojanje velikog broja identičnih predmeta po težini.

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

6.6 postotage Vaganje

Postotaktage function is useful for formulation and quality control, allowing you to measure a sample's weight as a percentage referentne težine.
