To calibrate a digital scale, you will need to follow these steps:

1. Find a weight that you know the exact weight of, such as a coin or a small weight. This weight will be used to calibrate the scale.
2. Place the weight on the scale and wait for the scale to stabilize.
3. Check the weight displayed on the scale. If it is not accurate, use the scale's calibration function to adjust the scale to the correct weight.
4. To calibrate the scale using the calibration function, follow the instructions in the user manual for your specific scale. The process may vary depending on the make and model of the scale.
5. Once the scale is calibrated, remove the weight and test the scale by weighing an object of known weight. If the scale displays the correct weight, the scale is properly calibrated. If the scale is still not accurate, you may need to repeat the calibration process or consult the user manual for further instructions.

I hope this helps! If you have any further questions, don't hesitate to ask.

Try this, it's a pdf but should have instructions

Try weighing an inanimate object, is the weight stable? Maybe you're stabalizing yourself by holding on to something? That will throw it off. all weight must be on the base and not moving to get an accurate reading. If it's still unstable it need new weight sensors and calibration. Probably not a DIY.

Calibrating a digital pocket scale like the Mega Weigh MGP-1014 ensures that it provides accurate measurements. Here are the general steps for calibrating such a scale:
Note: It's important to refer to your scale's user manual for specific instructions, as calibration methods can vary between different models.
What You'll Need:

• Calibration weights (these are weights with known, precise values)
• The Mega Weigh MGP-1014 scale
• A clean, stable surface for calibration

Steps:

1. Read the Manual: Familiarize yourself with the user manual that came with the scale. It should provide specific instructions on how to calibrate the scale.
2. Clean the Scale: Ensure that the scale's weighing platform is clean and free from any debris. This helps to prevent interference with the calibration process.
3. Power On: Turn on the scale and wait for it to stabilize, displaying "0.0" or the default reading.
4. Tare (Optional): If your scale has a tare function, you can use it to zero out the weight of any container you plan to use to hold the calibration weights. Place the empty container on the scale and press the tare button.
5. Select Calibration Mode: Many scales have a calibration mode that you need to access. Refer to your user manual to determine how to enter the calibration mode on the Mega Weigh MGP-1014.
6. Add Calibration Weight: Place a calibration weight of a known value onto the scale's platform. The weight should match the unit of measurement you plan to use (grams, ounces, etc.).
7. Calibration Procedure: Follow the specific instructions provided in the user manual to initiate the calibration procedure. This usually involves pressing buttons or following on-screen prompts. The scale will often ask you to confirm the weight value of the calibration weight you added.
8. Confirm or Adjust: The scale should display the weight you added as the calibration weight. Confirm that the displayed weight matches the known value of the calibration weight. If there's a discrepancy, follow the manual's instructions to adjust the calibration setting accordingly.
9. Repeat if Necessary: Some scales require calibration with multiple weights to ensure accuracy across the scale's entire range. If this is the case, follow the manual's instructions for using additional calibration weights.
10. Exit Calibration Mode: Once you've completed the calibration procedure, exit the calibration mode according to the instructions provided in the user manual.
11. Test with Known Items: After calibration, test the scale's accuracy by weighing objects of known weight to ensure that it's providing accurate readings.

Remember that the exact calibration process can vary depending on the scale model, so always refer to the user manual for the most accurate instructions. If you're unsure about any step, it's recommended to contact the manufacturer's customer support for assistance.

To calibrate the Panther Metler Toledo PTPN-1000X-023 weight scale, you can follow these general steps:

1. Turn on the scale and allow it to stabilize for a few minutes before use.
2. Press the "Calibrate" button on the scale's control panel. If there is no "Calibrate" button, check the scale's manual for instructions on how to enter calibration mode.
3. The scale will prompt you to place a known weight on the scale's platform. This weight should be within the scale's capacity and should be a weight that is used regularly in your process.
4. Place the known weight on the scale's platform and wait for the scale to stabilize.
5. Press the "Enter" button or follow the on-screen instructions to confirm that the weight is correct.
6. The scale will perform a series of internal checks and may prompt you to repeat the process with different weights.
7. Once calibration is complete, the scale will return to normal operation.

It's important to note that this is a general guide and the steps may vary depending on the specific model of your scale. Please refer to the instruction manual of your Panther Metler Toledo PTPN-1000X-023 scale for detailed instructions on how to calibrate it.
Additionally, it's important to ensure that the mixer is also properly calibrated and working correctly to ensure accurate measurement of your PVC material. It's recommended to contact the manufacturer or a professional technician for further assistance in case of any doubts or troubleshooting.

You did not identify your specific model but I believe it could be the seca 745. Product information can be found here:

There are also other linkson the page above which provide weighing instructions and hints that should be useful to you.

I don't know if the 354 can be calibrated.
Here are calibration instructions for the 374. It includes a toll free number to call seca in case this doesn't work.
