Homework Statement
For my lab report I am asked to calculate the error of a couple of measurements which I did with a lux meter. I know that the lux meter has tolerance(or accuracy?) 5%. The instrument is digital and it's last digit is 0.1. The maximum reading is 47.5 lux.
Homework Equations
:The Attempt at a Solution
:[/B][/B]Is the error 5% of each measurement? Should I add reading error? I'm pretty confused, sorry if it's a silly question.
