5. סעטאַפּ
5.1 אויספּאַקן און ערשטע דורכקוק
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 פּלייסמאַנט
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).
5.4 מאַכט קאַנעקשאַן
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 אויפוואַרעמונג צייט
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.

- דרוק די ON/OFF button to turn the balance on.
- דריקן און האַלטן די ON/OFF button to turn the balance off.
6.2 גרונטלעכע וואָג
To perform a basic weight measurement:
- Ensure the balance is level and has completed its warm-up.
- דרוק די טאַרע/נול button to set the display to 0.000g.
- Carefully place the item to be weighed on the center of the weighing pan.
- Wait for the reading to stabilize. The stable weight will be displayed.

6.3 טאַרע פֿונקציע
The tare function allows you to subtract the weight of a container, so only the net weight of the contents is measured.
- שטעלן אַ ליידיק קאַנטיינער אויף די ווייינג פּאַן.
- דרוק די טאַרע/נול button. The display will reset to 0.000g.
- Add the material to be weighed into the container. The display will show the net weight of the material.
6.4 יוניט קאַנווערזשאַן
The balance supports multiple weighing units. To change the unit:
- דרוק די UNIT 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 % (percentagאון).
- די אויסגעקליבענע איינהייט וועט ווערן געוויזן אויפן עקראַן.
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.
- דרוק די פּקס קנעפּל.
- Select the corresponding sample quantity using the UNIT קנעפּל.
- דרוק פּקס again to confirm. The balance is now in counting mode.
- Add more items, and the display will show the total count.
6.6 פּראָצענטtage ווייינג
די פּראָצענטtage function is useful for formulation and quality control, allowing you to measure a sample's weight as a percentagE פון אַ רעפֿערענץ וואָג.
- שטעלן די רעפֿערענץ sampשטעלן אויף די ווייינג פּאַן.
- דרוק די UNIT button until '%' is displayed. The reference weight will be set as 100%.
- אַראָפּנעמען די רעפֿערענץ sample.
- Place subsequent samples on the pan. Their weight will be displayed as a percentagE פון די רעפֿערענץ וואָג.
6.7 קאַלאַבריישאַן
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.
- דריקן און האַלטן די CAL button until 'CAL' appears on the display.
- 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.
- Remove the calibration weight.
