6.8.3 Example: Calculation of the data volume for results files
Prerequisite
• 4-step tightening program respectively with torque/angle target function and torque/angle/gradient
monitoring function
• 2000 graph points
Assumptions
• The application part can be ignored for theoretical calculation of the total size of the file.
• Always user-friendly formatting ( -> file size is approx. 20 % higher)
• Single channel without anything: 10 kBytes
• Single-channel graph data torque/angle/time, base64 coding: 40 kBytes
• Single-channel graph data torque/angle/time, without base64 coding: 70 kBytes
• Single-channel graph data, all with base64 coding: 75 kBytes
• Single-channel graph data, all without base64 coding: 120 kBytes
Calculation:
Application = Single channel x Number of channels
