5. Nastavení
5.1 Vybalení a počáteční kontrola
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 Umístění
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 Vyrovnání váhy
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 Připojení napájení
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 Doba zahřívání
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. Návod k obsluze
6.1 Zapnutí/vypnutí
- Stiskněte tlačítko ON/OFF tlačítko pro zapnutí váhy.
- Stiskněte a podržte ON/OFF tlačítko pro vypnutí váhy.
6.2 Základní vážení
To perform a basic weight measurement:
- Ensure the balance is level and has completed its warm-up.
- Stiskněte tlačítko TARE/NULA tlačítko pro nastavení zobrazení na 0.000 g.
- Opatrně umístěte vážený předmět do středu vážicí misky.
- Wait for the reading to stabilize. The stable weight will be displayed.

6.3 Funkce tárování
The tare function allows you to subtract the weight of a container, so only the net weight of the contents is measured.
- Na misku váhy položte prázdnou nádobu.
- Stiskněte tlačítko TARE/NULA button. The display will reset to 0.000g.
- Vložte vážený materiál do nádoby. Na displeji se zobrazí čistá hmotnost materiálu.
6.4 Převod jednotek
The balance supports multiple weighing units. To change the unit:
- Stiskněte tlačítko JEDNOTKA 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 % (percentagE).
- Vybraná jednotka se zobrazí na obrazovce.

6.5 Parts Counting (PCS)
This function allows you to count a large number of identical items by weight.
- Place a known quantity of items (e.g., 10, 20, 50, 100, 150, 200, 250, 500) on the pan.
- Stiskněte tlačítko PCS tlačítko.
- Select the corresponding sample quantity using the JEDNOTKA tlačítko.
- Stiskněte PCS again to confirm. The balance is now in counting mode.
- Add more items, and the display will show the total count.
6.6 procenttage Vážení
Procentatage function is useful for formulation and quality control, allowing you to measure a sample's weight as a percentage referenční hmotnosti.
- Umístěte odkaz sample na misku váhy.
- Stiskněte tlačítko JEDNOTKA button until '%' is displayed. The reference weight will be set as 100%.
- Odstraňte odkaz sample.
- Place subsequent samples on the pan. Their weight will be displayed as a percentage referenční hmotnosti.
6.7 Kalibrace
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.
- Ensure the weighing pan is empty and the balance is stable.
- Stiskněte a podržte CAL tlačítko, dokud se na displeji nezobrazí „CAL“.
- The display will then show the required calibration weight (e.g., 500.000g).
- Carefully place the specified calibration weight (provided) onto the center of the weighing pan.
- Wait for the balance to automatically calibrate. Once complete, the display will show 'PASS' or return to normal weighing mode.
- Odstraňte kalibrační závaží.
