How do you calibrate aws scales?

To calibrate AWS scales, you will need to use a set of known weights to adjust the scale's accuracy. Here's a step-by-step guide:

1. Gather the necessary tools:

- Set of calibrated test weights

- Small screwdriver or calibration tool (usually provided with AWS scales)

- A stable, level surface to place the scale

2. Power on the scale:

- Connect the scale to a power source or insert batteries if it's a battery-powered model.

3. Zero the scale:

- Place the scale on a stable, level surface and press the "Zero" or "Tare" button to set the display to zero.

4. Add the first test weight:

- Place the smallest weight from the calibration kit on the scale platform and wait for the display to stabilize.

5. Adjust the scale:

- Use the small screwdriver or calibration tool to adjust the calibration knob or screw until the display matches the weight of the test weight.

6. Repeat for larger weights:

- Continue adding larger test weights one at a time and adjust the scale accordingly until you have used all the weights.

7. Verify accuracy:

- Once you have gone through all the test weights, remove them from the scale and check if the display shows zero again.

8. Save the calibration:

- Some AWS scales have a "Save" or "Calibrate" button. Press this button to store the new calibration data in the scale's memory.

9. Test the calibration:

- Remove all weights and place an object of known weight on the scale. The scale should display the accurate weight.

Remember that calibration should be performed regularly according to the manufacturer's recommendations to ensure the scale's accuracy. If the scale consistently shows incorrect readings, it may need to be sent to an authorized service center for professional calibration.
