9.3.2 STEP 3 -- Uncertainty sources: one by one

[@karinalucas8914]

Thanks a lot for the video. It's helping me a lot.
I have a question... we don't have to account the equipment's accuracy for the uncertainty calculation?
For example:
I have to determinate the uncertainty of a pH measurement. The manufacturer of the pH meter specifies the equipment's accuracy: +- 0.2 pH unit. So, using this information my uncertainty should be at least 0.2 pH unit. Does it work this way?
Thank you again.
