Measurement & Metrology
Vernier Calipers
Learn the instrument layout and reading process through an interactive 2D visual lesson instead of relying only on a static diagram.
Interactive Engineering Learning
DiplomaOne is adding interactive HTML lessons alongside notes and paper solutions. These lessons are designed to help students understand a machine or instrument visually before revising it from notes.
Start with a topic, watch the working sequence, then return to your notes for formulas, definitions and examination preparation. The interactive material opens in DiplomaOne's internal viewer rather than sending you to another website.
Measurement & Metrology
Micrometer Screw Gauge
Use the interactive lesson to understand the main parts and how the screw mechanism supports precise measurement.
Thermal Measurement
Mercury Thermometer
Explore the thermometer structure and the visual relationship between temperature change and the indication system.
Thermal Measurement
