2. Plug the provided AC adapter into the interface.
3. Connect the adapter to a suitable power outlet.

3. Operasie

3.1 Krag aan/af

Druk die AAN/AF button to turn the balance on or off. The display will show "0.00" when ready for use.

3.2 Tarrafunksie

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

1. Place an empty container on the weighing pan. The display will show its weight.
2. Druk die TARA/KAL knoppie. Die skerm sal na "0.00" herstel word.
3. Add the items you wish to weigh into the container. The display will now show only the net weight of the items.

Refer to the video in Section 2.2 for a visual demonstration of the Tare function.

3.3 Eenheid Omskakeling

The balance supports 19 different weighing units. To switch between units:

• Druk die EENHEID button repeatedly to cycle through the available units: g, kg, ct, T, TAR, dr, PKT, GN, TMR, gsm, tIJ, mo, dwt, oz, lb, tlT, ozt, tIH, %.
• The selected unit will be displayed on the LCD screen.

Refer to the video in Section 2.2 for a visual demonstration of unit conversion.

3.4 Piece Counting Function

This function allows you to count a quantity of items based on a sample weight. Ensure that individual items have a consistent weight (differences within 5%).

1. With the balance displaying "0.00", press and hold the PCS button for approximately 3 seconds to enter counting mode.
2. The display will show a sample size (e.g., "10", "20", "50", "100"). Press EENHEID om die verlangde s te kiesampdie grootte.
3. Place the corresponding number of sample items on the pan (e.g., 10 items if "10" is selected).
4. Druk PCS again to confirm the sample. The display will show the number of items.
5. You can now add more items, and the balance will count them based on the sample gewig.

3.5 persenttage Funksie

Die persentasietage function allows you to weigh materials as a percentage of a reference quantity.

1. Place your reference material on the weighing pan.
2. Druk en hou die EENHEID button until "%" appears on the display. The reference material's weight will now be displayed as 100%.
3. Add other materials, and their weights will be shown as a percentage of the reference material.

3.6 Kalibrasie

To ensure continued accuracy, periodic calibration is recommended. A 5000g calibration weight (not included) is required.

1. Ensure the balance is on a stable, level surface and displaying "0.00".
2. Druk en hou die TARA/KAL button until "CAL" appears on the display.
3. The display will then show the required calibration weight (e.g., "5000.00g").
4. Carefully place the 5000g calibration weight in the center of the weighing pan.
5. Wait for the display to stabilize and show "PASS" or return to "0.00".
6. Remove the calibration weight. The balance is now calibrated.
