3. Setup
3.1 Unpacking and Inspection
Carefully remove the balance from its packaging. Inspect all components for any signs of damage. The package should contain the balance unit, weighing pan, draft shield (if applicable), and power adapter.
This image displays the KERN PFB 600-2 Precision Laboratory Balance. It features a white and blue casing, a circular weighing pan, and a clear glass draft shield. The digital display shows '0.00 g', and control buttons for 'PRINT/ESC', 'MODE', 'PCS', '%', 'TARE', and 'ON/OFF' are visible on the front panel.
3.2 Placement and Leveling
- Place the balance on a firm, level, and vibration-free surface.
- Adjust the leveling feet located at the bottom of the balance until the air bubble in the spirit level (usually located near the display) is centered.
3.3 Power Connection
Connect the power adapter to the balance and then plug it into a suitable power outlet. Allow the balance to warm up for at least 30 minutes before initial use for optimal accuracy.
4. Operating Instructions
4.1 Power On/Off
- Press the ON/OFF button to turn the balance on.
- Press and hold the ON/OFF button to turn the balance off.
4.2 Basic Weighing
- Ensure the balance is level and the display shows '0.00 g'. If not, press the TARE button to zero the display.
- Carefully place the item to be weighed onto the center of the weighing pan.
- Read the stable weight value displayed.
4.3 Tare Function
The tare function allows you to weigh items in a container without including the container's weight.
- Place the empty container on the weighing pan.
- Press the TARE button. The display will show '0.00 g'.
- Add the substance to be weighed into the container. The display will show only the net weight of the substance.
4.4 Unit Conversion
Press the MODE button to cycle through available weighing units (e.g., grams, ounces, pounds, carats, etc.). The active unit will be indicated on the display.
4.5 Counting Function (PCS)
This function allows for counting a large number of identical items.
- Place a known quantity of items (e.g., 10, 20, 50, 100 pieces) on the pan.
- Press the PCS button. The display will prompt you to select the sample size.
- Use the MODE or % buttons to select the corresponding sample size (e.g., P10 for 10 pieces).
- Press PCS again to confirm. The balance is now in counting mode.
- Add more items, and the display will show the total count.
4.6 Percentage Weighing (%)
This function allows you to determine the percentage of a sample relative to a reference weight.
- Place the reference sample on the weighing pan.
- Press the % button. The display will show '100.00%'.
- Remove the reference sample and place the sample to be measured. The display will show its weight as a percentage of the reference sample.
4.7 Print Function
If connected to a compatible printer or PC, pressing the PRINT/ESC button will send the current weighing data to the connected device.
5. Maintenance
5.1 Cleaning
- Always disconnect the power before cleaning.
- Wipe the balance exterior with a soft, damp cloth. Use a mild detergent if necessary.
- Do not use abrasive cleaners, solvents, or immerse the balance in water.
- Clean the weighing pan regularly to prevent accumulation of dust or debris.
5.2 Storage
When not in use for extended periods, store the balance in a dry, dust-free environment at room temperature. Ensure the draft shield is in place to protect the weighing mechanism.
5.3 Recalibration
Periodic calibration with certified weights is recommended to maintain accuracy. Refer to the balance's specific calibration procedure in the full technical manual or contact KERN support for guidance.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display shows 'Err' or 'Overload' | Weight exceeds maximum capacity. | Remove excess weight. |
| Inaccurate readings | Balance not level, vibrations, temperature fluctuations, need for calibration. | Check leveling, move to stable surface, allow warm-up, perform calibration. |
| Display does not turn on | No power, faulty adapter. | Check power connection, try a different outlet, verify adapter functionality. |
| Display shows '0.00' but weight is on pan | Tare function was activated with item on pan. | Remove item, press TARE to zero, then re-weigh. |
