5. Instellen

5.1 Uitpakken en eerste inspectie

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 Plaatsing

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).

Figuur 5.1: Horizontal Adjustment. Adjust leveling feet until the bubble is centered. Proper leveling is essential for accuracy.

5.4 Stroomaansluiting

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 Opwarmtijd

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. Gebruiksaanwijzing

6.1 In-/uitschakelen

  • Druk op de AAN/UIT button to turn the balance on.
  • Houd de AAN/UIT button to turn the balance off.

6.2 Basiswegen

To perform a basic weight measurement:

  1. Ensure the balance is level and has completed its warm-up.
  2. Druk op de TARRA/NUL button to set the display to 0.000g.
  3. Plaats het te wegen voorwerp voorzichtig in het midden van de weegschaal.
  4. Wacht tot de meting stabiel is. Het stabiele gewicht wordt weergegeven.

6.3 Tarrafunctie

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

  1. Plaats een lege container op de weegpan.
  2. Druk op de TARRA/NUL button. The display will reset to 0.000g.
  3. Voeg het te wegen materiaal toe aan de container. Op het display wordt het nettogewicht van het materiaal weergegeven.

6.4 Eenheidsconversie

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

  • Druk op de EENHEID 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 % (percentagen).
  • Het geselecteerde apparaat wordt op het scherm weergegeven.

6.5 Parts Counting (PCS)

This function allows you to count a large number of identical items by weight.

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

6.6 procenttage Wegen

De procenttage function is useful for formulation and quality control, allowing you to measure a sample's weight as a percentage van een referentiegewicht.

  1. Plaats de referentie sample op de weegpan.
  2. Druk op de EENHEID button until '%' is displayed. The reference weight will be set as 100%.
  3. Verwijder de referentie sampik.
  4. Place subsequent samples on the pan. Their weight will be displayed as a percentage van het referentiegewicht.

6.7 Kalibratie

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. Houd de KAL 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. Verwijder het kalibratiegewicht.
