CGOLDENWALL 5000g 0.01g Højpræcisionslaboratorievægt Brugsanvisning

1. Introduktion

This manual provides detailed instructions for the proper use and maintenance of your CGOLDENWALL 5000g 0.01g High Precision Laboratory Balance. Designed for accuracy and reliability, this electronic scientific weighing scale is equipped with a high-sensitivity sensor to deliver precise and rapid results with an accuracy of 0.01g.

The analytical balance features a durable ABS body and a 180x140mm stainless steel weighing pan. It includes adjustable feet and a level bubble to ensure accurate measurements in various environments. The scale is pre-calibrated before shipment; calibration should only be performed if significant errors are observed, following the instructions provided.

Key functionalities include 13 unit conversions (g, ct, oz, lb, %, etc.), tare/zero, counting function, and calibration capabilities. The LCD display with blue backlighting ensures clear readability in diverse lighting conditions, also indicating low battery and overload status.

2. Opsætning

2.1 Udpakning og komponentidentifikation

2.2 Strømforsyning til vægten

The scale can be powered using two methods:

• 110V AC Adapter: Connect the included AC adapter to the power port on the scale and then to a standard electrical outlet.
• 9V DC batteri: For portable use, a 9V battery (not included) can be inserted into the battery compartment located on the underside of the scale.

Figure 2: Illustration of the two powering modes: 110V AC adapter and 9V DC battery.

2.3 Nivellering af vægten

For accurate measurements, ensure the scale is placed on a stable, level surface. Use the adjustable feet at the bottom of the scale to level it. The built-in horizontal bubble indicator will show when the scale is perfectly level.

Figure 3: The horizontal bubble and adjustable feet ensure stability and accurate leveling.

3. Betjeningsvejledning

3.1 Grundlæggende vejning

To perform a basic weighing operation:

1. Place the item directly onto the stainless steel weighing pan.
2. Aflæs vægten vist på LCD-skærmen.

Figur 4: Eksample of a basic weighing operation.

3.2 Tara funktion

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

1. Placer den tomme beholder på vejepladen.
2. Press the "TARE/ZERO" button. The display will reset to 0.00g.
3. Læg den vare, der skal vejes, i beholderen. Displayet viser varens nettovægt.

Figure 5: Step-by-step guide for using the tare function.

3.3 Enhedskonvertering

The scale supports 13 different weighing units. To switch between units:

• Press the "UNIT" button repeatedly to cycle through the available units: grams (g), carats (ct), ounces (oz), pounds (lb), Newtons (N), pennyweights (dwt), drams (dr), grains (GN), taels (tlT, T, T/A/R), and percentage (%).

Figure 6: The unit conversion feature allows switching between various measurement units.

3.4 Tællefunktion

The counting function allows you to count multiple small items of uniform weight.

1. Placer somample quantity of items (e.g., 10, 20, 50, 100 pieces) on the pan.
2. Press the "PCS" button and select the corresponding sample mængde.
3. Tilføj flere varer til panden, og vægten viser det samlede antal.

3.5 Kalibrering

The scale is pre-calibrated. However, if you notice significant discrepancies, you may need to recalibrate it. This model (5000g) requires a 2000g calibration weight, which is not included due to shipping considerations. Calibration weights are readily available for purchase.

3.5.1 Single Point Calibration

1. Ensure the scale is empty and stable.
2. Press and hold the "CAL" button until "-CAL-" flashes on the display.
3. The scale will then flash the required calibration weight (e.g., "2000.00g").
4. Carefully place the specified calibration weight onto the center of the weighing pan.
5. The scale will stop flashing and display "PASS" or return to normal weighing mode, indicating successful calibration.

3.5.2 Multi-Points Calibration

For more precise calibration across the weighing range, multi-points calibration can be performed.

1. Ensure the scale is empty and stable.
2. Press and hold the "CAL" button until "-CAL-" flashes.
3. While "-CAL-" is flashing, press and hold the "PCS" button to enter multi-points calibration mode.
4. The scale will prompt for successive calibration weights. Place each weight as prompted.
5. Follow the on-screen instructions until the calibration process is complete.

4. Vedligeholdelse

Proper maintenance ensures the longevity and accuracy of your laboratory balance.

• Rensning: Tør vægtens overflade og vejepladen af ​​med en blød kludamp cloth. Avoid abrasive cleaners or solvents that could damage the finish or internal components. Ensure no liquids enter the scale's interior.
• Opbevaring: Store the scale in a clean, dry, and stable environment, away from extreme temperatures, humidity, vibrations, and strong electromagnetic fields.
• Håndtering: Handle the scale with care. Avoid dropping it or subjecting it to sudden impacts, as this can affect its precision.
• Vejepande: Always ensure the weighing pan is clean and free of debris before use.

5. Fejlfinding

If you encounter issues with your scale, refer to the following common troubleshooting steps:

• Upræcise læsninger:
  • Ensure the scale is on a stable, level surface. Use the level bubble to verify.
  • Check for drafts or air currents that might affect readings.
  • Verify that the weighing pan is correctly seated and free of obstructions.
  • Udfør en kalibrering som beskrevet i afsnit 3.5.
• Skærmen tændes ikke:
  • Check the power connection if using the AC adapter.
  • If using battery power, ensure the 9V battery is correctly installed and not depleted. Replace if necessary.
• "EEEE" or Overload Indication:
  • This indicates the weight on the pan exceeds the scale's maximum capacity (5000g). Remove some weight immediately to prevent damage.
• "Lo" or Low Battery Indication:
  • If using battery power, replace the 9V battery. If using AC adapter, this may indicate a power supply issue.
