Small Electronic Scale: Disassembly to Calibration

Learn how to modify a small electronic scale with a maximum capacity of 3000g and an accuracy of 0.1g without risking damage. If you have a small electronic scale with a maximum weighing capacity of 3000g and an accuracy of 0.1g, and you want to modify it without damaging it, you can follow the steps outlined in this text to try disassembling it. The small electronic scale is as shown in the image below:

Step-by-Step Process:

1. Initial Assessment:

· Examine the backside of the scale to identify the power source: two AAA batteries ensure optimal energy conservation.

2. Disassembly Procedure:

· Remove the two screws located on the bottom shell to facilitate further disassembly. These screws are pivotal in connecting the strain gauge and outer casing.

· Navigate the complexity of disassembling the upper and lower shells, each secured by four additional screws.

3. Component Analysis:

· Delve into the intricacies of the strain gauge, mainboard, and peripheral elements, gaining insight into their functionality and durability.

4. Modification Potential:

· The backlight panel beneath the LCD screen, LEDs, and board are integrated. If you want to change the backlight color, it might be a bit tricky. If you want to change it, gently heating it up can help peel off the backlight to replace it with LED lights for a different color. However, if the LEDs and the acrylic board are integrated, they cannot be separated, making it difficult to change the LEDs. You can try it yourself later.

5. Calibration and Reassembly:

· Restore the scale to its original configuration, ensuring precision and accuracy by utilizing a nickel as a calibration weight.

· Validate the integrity of the modifications, confirming that the scale performs as intended after reassembly.

Conclusion:

By following this step-by-step guide, you can safely disassemble and potentially modify your small electronic scale while maintaining its functionality and accuracy.
