5. Opstelling

5.1 Uitpak en Aanvanklike Inspeksie

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 Plasing

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 Die balans gelykmaak

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 Kragverbinding

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. Bedryfsinstruksies

6.1 Krag aan/af

  • Druk die AAN/AF button to turn the balance on.
  • Druk en hou die AAN/AF button to turn the balance off.

6.2 Basiese Weeg

To perform a basic weight measurement:

  1. Ensure the balance is level and has completed its warm-up.
  2. Druk die TARE/NUL button to set the display to 0.000g.
  3. Plaas die item wat geweeg moet word versigtig in die middel van die weegpan.
  4. Wait for the reading to stabilize. The stable weight will be displayed.

6.3 Tarrafunksie

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

  1. Plaas 'n leë houer op die weegpan.
  2. Druk die TARE/NUL button. The display will reset to 0.000g.
  3. Voeg die materiaal wat geweeg moet word by die houer. Die skerm sal die netto gewig van die materiaal wys.

6.4 Eenheid Omskakeling

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

  • Druk die 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).
  • The selected unit will be displayed on the screen.

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 die PCS knoppie.
  3. Select the corresponding sample quantity using the EENHEID knoppie.
  4. Druk 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 persenttage Weeg

Die persentasietage function is useful for formulation and quality control, allowing you to measure a sample's weight as a percentage van 'n verwysingsgewig.

  1. Plaas die verwysing sample op die weegpan.
  2. Druk die EENHEID button until '%' is displayed. The reference weight will be set as 100%.
  3. Verwyder die verwysing sample.
  4. Place subsequent samples on the pan. Their weight will be displayed as a percentage van die verwysingsgewig.

6.7 Kalibrasie

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. Druk en hou die 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.
