1. Data analysis of hot topics across the entire network (last 10 days)
| Platform | Hot search keywords | Number of discussions (10,000) |
|---|---|---|
| Douyin | Caliper usage tutorial | 42.5 |
| Industrial measuring tools | 18.3 | |
| Station B | Machining skills | 36.2 |
| Zhihu | Caliper Buying Guide | 12.7 |
2. Structural understanding of caliper with watch
The caliper with watch mainly consists of the following components:
| Part name | Function description |
|---|---|
| main ruler | Basic scale, minimum scale 1mm |
| vernier scale | Movable auxiliary ruler with dial display |
| Dial | Pointer display, accuracy 0.02mm |
| depth rod | Measure hole depth or step height |
3. Detailed explanation of reading method (step-by-step instructions)
1.Main scale reading: First read the whole millimeter of the main scale corresponding to the vernier "0" scale line.
2.Dial reading: Observe the position of the dial pointer. Each small grid represents 0.02mm.
3.Calculation example: If the main scale displays 15mm and the dial pointer points to the 7th division, the measured value is 15.14mm (15+0.02×7).
| Measurement example | Reading method | result |
|---|---|---|
| Main ruler 23mm | The dial pointer points to 15 divisions | 23.30mm |
| Main ruler 7mm | The dial pointer points to 3 divisions | 7.06mm |
4. Frequently Asked Questions (from popular discussions)
1.Q: Why does the dial appear to be inaccurate in returning to zero?
A: The gear may be misaligned due to impact and requires professional calibration.
2.Q: How much force should be applied when measuring?
A: Hold the caliper lightly so that the measuring surface just touches the workpiece, and you can hear a "click" sound.
3.Q: How to maintain the caliper with watch?
A: Clean regularly with absolute alcohol, loosen the fastening screws during storage, and avoid magnetic environments.
5. Purchasing suggestions (comparison of popular models)
