The top image depicts the vernier caliper with its jaws tightly closed while the bottom image depicts the vernier caliper with its jaws closed on an object. Find the zero error and the correct reading of the vernier calipers below.

$$\text{Zero Error }=-0.03 \text{cm}$$

$$0.06 \text{cm}-(-0.03 \text{cm}) = 0.09 \text{cm}$$

$$\text{Zero Error }=+0.03 \text{cm}$$

$$1.06 \text{cm}-(+0.03 \text{cm}) = 1.03 \text{cm}$$

$$\text{Zero Error }=-0.06 \text{cm}$$

$$6.43 \text{cm}-(-0.06 \text{cm}) = 6.49 \text{cm}$$

1. how is the second error +0.03 is it not +0.04?

2. does anyone know how the zero error affects the depth rod of the Vernier caliper ? if it does then how ,if doesn’t then why?

3. The topic is explained in a simpler and understandable manner. It is really very helpful.

• Is it a joke!!!!!!

4. how this error became 0.03

• Dear Hamna…for negative zero error formula will be (10-coinciding div)*LC
So we have -(10-7)*0.01=-0.03 zero error????

• we dont count the line coinciding with the main scale I think ๐

5. vernier callipers its good for us future engineers but tough to read on my first day at secondary school whoosh it good to be provided online for readers

6. Thanks! I understand how to read off a vernier caliper already ๐
