Figure 1: Overview of the Kern KB 2000-2N Precision Laboratory Balance. This image displays the balance from a front-side angle, highlighting the weighing pan, the LCD display, and the control buttons. The balance features a silver finish and a compact design suitable for laboratory environments.
- Weighing Pan: Stainless steel platform for placing items to be weighed.
- Display: LCD screen showing weight readings and operational indicators.
- Control Panel: Buttons for power, tare, unit selection, and calibration.
- Level Indicator: Bubble level to ensure the balance is perfectly horizontal.
- Adjustable Feet: For leveling the balance.
- Power Adapter Port: Connection for the external power supply.
Setup Instructions
- Unpacking: Carefully remove the balance and all accessories from the packaging. Retain the packaging for future transport or storage.
- Placement: Place the balance on a stable, level surface free from vibrations, drafts, and direct sunlight. Avoid locations near heat sources or strong electromagnetic fields.
- Leveling: Use the adjustable feet at the bottom of the balance to ensure the bubble in the level indicator is centered. This is crucial for accurate measurements.
- Power Connection: Connect the provided power adapter to the balance's power port and then plug it into a suitable electrical outlet.
- Initial Warm-up: Allow the balance to warm up for at least 30 minutes after connecting power before performing any measurements or calibration. This stabilizes the internal components.
Operating Instructions
Turning On/Off
- To Turn On: Press the [ON/OFF] button. The display will show a self-test sequence and then settle at 0.00 g.
- To Turn Off: Press and hold the [ON/OFF] button until the display turns off.
Basic Weighing
- Ensure the balance is level and displaying 0.00 g. If not, press the [ZERO] or [TARE] button to zero the display.
- Carefully place the item to be weighed onto the center of the weighing pan.
- Wait for the reading on the LCD display to stabilize. The stability indicator (if present) will confirm a stable reading.
- Record the displayed weight.
- Remove the item from the pan. The display should return to 0.00 g or a negative value if tare was used.
Tare Function
The tare function allows you to subtract the weight of a container, so only the net weight of the contents is measured.
- Place the empty container on the weighing pan.
- Wait for the reading to stabilize.
- Press the [TARE] button. The display will reset to 0.00 g, indicating the container's weight has been tared.
- Add the material to be weighed into the container. The display will show the net weight of the material.
- To clear the tare, remove the container from the pan and press [TARE] again, or turn the balance off and on.
Unit Conversion
Your balance may support multiple weighing units. Refer to the balance's specific unit conversion procedure, typically involving a [UNIT] button. Pressing this button cycles through available units (e.g., grams, ounces, pounds, carats).
Maintenance
Cleaning
- Always disconnect the balance from the power supply before cleaning.
- Use a soft, damp cloth with a mild detergent to clean the exterior surfaces.
- Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish and internal components.
- Ensure no liquids enter the balance housing or display.
- Clean the stainless steel weighing pan regularly to prevent residue buildup.
Storage
- When not in use for extended periods, store the balance in a dry, dust-free environment.
- If possible, use the original packaging for storage to protect against impacts.
- Avoid storing in areas with extreme temperature fluctuations or high humidity.
Calibration
Regular calibration is essential to maintain the accuracy of your precision balance. Refer to the manufacturer's specific calibration procedure, which typically involves using certified calibration weights. If you are unsure, consult the manufacturer's support resources.
Troubleshooting
This section addresses common issues you might encounter with your Kern KB 2000-2N balance.
| Problem | Possible Cause | Solution |
|---|---|---|
| Display shows "Err" or error code | Overload, unstable environment, internal fault. | Remove excess weight. Ensure stable surface. Turn off and restart. If persistent, contact support. |
| Inaccurate readings | Balance not level, drafts, vibrations, not warmed up, needs calibration. | Level the balance. Move to a stable location. Allow warm-up time. Perform calibration. |
| Display does not turn on | No power, faulty adapter, power button issue. | Check power connection and outlet. Ensure adapter is functional. Try pressing the power button firmly. |
| Weight fluctuates | Drafts, vibrations, unstable surface, temperature changes. | Relocate the balance to a more stable environment. Close windows/doors to eliminate drafts. |
