SUMMARY

The discussion focuses on determining the type of measurement for voltage using a multimeter and calculating associated errors. The measurements provided are U1 = 15.05, U2 = 15.06, and U3 = 15.05, with a relative error of the multimeter set at 4%. The main tasks include calculating the error using the small sample method (Student distribution) and determining the instrumental error. The user has successfully identified the measurement type as direct - single but requires assistance with the calculations outlined in the homework instructions.

PREREQUISITES
  • Understanding of direct measurement techniques
  • Familiarity with multimeter specifications and error calculations
  • Knowledge of statistical methods, specifically the Student distribution
  • Basic principles of electrical measurements and voltage
NEXT STEPS
  • Calculate the error using the small sample method (Student distribution)
  • Determine the instrumental error based on multimeter specifications
  • Review the principles of error analysis in electrical measurements
  • Explore statistical methods for analyzing measurement data
USEFUL FOR

Students in physics or engineering courses, electrical engineers, and anyone involved in experimental measurements and error analysis will benefit from this discussion.

2) Calculate the instrumental error
Relevant Equations
The equation is missing
I was only able to determine the type of measurement, it turns out to be direct - single. I can't find 1) and 2) of the homework instructions. I have the following data:Voltage:
U1, B = 15.05
U2, B = 15,06
U3, B = 15,05
Relative error of the multimeter
ΔU/U, % = 4

Help please
