![]() ![]() A calliper usually consists of an inner jaw and an outer jaw. Add these two together to obtain an effective reading.įormula used: Final reading = Main scale reading + Vernier scale readingĪ Vernier Calliper is an instrument that is used to make very accurate linear measurements. The division to which the zero on the Vernier scale is closest to is the main scale reading, and the division of the Vernier scale that first coincides with a division on the main scale gives the Vernier scale reading. ![]() a kind of collapsible vernier caliper reading demonstrator according to claim 1 is characterized in that the main scale of main structure and vernier scale base plate can be with wooden, and plastics matter, organic glass light material are gone up powerful permanent magnet with the seccotine stickup and be made.Hint: Recall that each division on the main scale represents 1mm and each division on the Vernier scale represents 0.1mm. The major structure consists of two parts of a main scale and a vernier, and is characterized in that reading scales of the original vernier caliper are amplified by about 10-100 times, and are directly attached on a magnetic bottom plate, and the bottom plate of the main scale and the vernier is divided into a plurality of section so as to realize folding. The utility model is an auxiliary device used for vernier caliper teaching demonstration. The teaching demonstrator can be folded after use. The reading demonstrator has high visibility, enables the whole class, especially students in the back rows to clearly see presentation content, is simple in operation, and is favorable for improving learning interests of students. The utility model provides a folding vernier caliper reading demonstrator, which is affixed to an iron blackboard for assisting physical experiments of Measurement of Length for grade one of high school, so as to enable students to grasp the principle and reading method of the vernier caliper in the experiments.
