Multimeter and Logger show different values

When i measure Voltage in Multimeter mode it shows 3.08V and when i switch to the logger it shows 3.13V

Which one is correct? Why is it different in the first place?

  Hello Stephan,

  The multimeter value is most accurate,

  As for why there is  a difference the most likely answer is in logger the device doesnt auto range, it selects its range based off the users settings (we are working on making this more obvious) so what is most likely happening is the range that is being used is less accurate at lower voltages (you may be using 50V range to measure 3V)

  Thanks for your answer. It is indeed very unintuitive. You are talking about the voltage range. But where can i change the voltage range??

  I also get the error "Values clipped at top range". But where can i set the voltage range?

  Hi Stephan Stange,

  If you are seeing the 'Values clipped at top range' error, either press 'Mode' and increase the unit selector, or pinch the waveform/log to zoom out on the y-axis.

  This logger guide may be of help too: https://www.youtube.com/watch?v=oDhL37yekRg
