Sikkerhetsregler

• Always operate the balance on a stable, level surface.
• Avoid placing the balance near strong electromagnetic fields, vibrations, or air currents.
• Do not overload the balance beyond its maximum capacity of 110 g to prevent damage.
• Use only the provided UL-certified power cable.
• Keep the balance clean and free from dust and corrosive substances.
• Do not attempt to disassemble or repair the balance yourself. Contact qualified service personnel.

Oppsett

1. Utpakking og plassering

Carefully remove all components from the packaging. Place the balance on a sturdy, level, and vibration-free workbench, away from direct sunlight, heat sources, and strong air currents (e.g., air conditioning vents).

2. Montering

• Place the weighing pan onto the pan support in the center of the balance.
• Assemble the draft shield around the weighing pan. Ensure all panels are securely in place to protect against air disturbances.

3. Utjevning

The balance must be perfectly level for accurate measurements. Adjust the adjustable feet at the bottom of the balance until the bubble in the spirit level (located on the front or side of the balance) is centered.

4. Strømtilkobling

Connect the UL-certified power cable to the 6V DC input port on the rear of the balance and then plug it into a suitable power outlet.

5. Warm-up Time

After connecting to power, allow the balance to warm up for at least 30 minutes before use. This stabilizes the internal components and ensures optimal accuracy.

• Trykk og hold inne MAKT button to turn the balance off.

2. Enhetskonvertering

Trykk på MODUS button to cycle through available weighing units: grams (g), carats (ct), ounces (oz), and grains (gn). The selected unit will be displayed on the LCD.

Figure 5: Available weighing units.

3. Tareringsfunksjon

To subtract the weight of a container, place the empty container on the weighing pan and press the 0/T (Tare) button. The display will reset to zero, allowing you to measure only the net weight of the contents.

4. Kalibrering

Regular calibration ensures the accuracy of your balance. It is recommended to recalibrate if the balance has been moved or if accuracy is critical. Refer to the specific calibration procedure in the full manual for detailed steps. Generally, this involves pressing the CAL button and following on-screen prompts using the provided calibration weight.

5. Piece Counting Function

The balance includes a piece-counting function for counting multiple items of uniform weight. To use this feature:

• Place a known number of sample pieces (e.g., 10, 20, 50, or 100) on the pan.
• Trykk på SETT button and follow the instructions to input the sample mengde.
• Når sample is registered, remove it and place the bulk quantity of items on the pan. The display will show the total count.

6. RS232 Data Transfer

The balance is equipped with an RS232 serial port for data transfer to a computer or other compatible device. Connect a compatible RS232 cable (not included) to the port on the rear of the balance. Refer to your software documentation for data acquisition procedures.

7. Overbelastningsbeskyttelse

The balance features an overload alarm function. If the weight on the pan exceeds the maximum capacity (110 g), an alarm will sound, and an error message may appear on the display. Immediately remove excess weight to prevent damage to the weighing sensor.

Vedlikehold

1. Rengjøring

Clean the balance regularly with a soft, damp cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the display or housing. Ensure no liquids enter the internal components.

2. Oppbevaring

When not in use for extended periods, store the balance in a dry, dust-free environment. It is recommended to keep the draft shield assembled to protect the weighing pan.
