AC Voltage Logging

Hi all,

In order to fix solar inverter disconnections, I need to monitor AC voltage over time.

I do not manage to do it with Pockit Pro.

Can someone help me doing this ?

 

thanks :-)

  Hi Ferdinand d'Aspremont Lynden,

  Over what length of time do you intend to measure? And how frequently do you need to have measurements taken?

  You can measure AC voltage with your Pokit Pro in the Logger function. Once in the Logger function, select 'Mode', then select 'AC' and set the sample interval. Make sure the switch on your Pokit Pro is set to 'V'. You can then begin logging with the red Pokit button.

  hi Lachlan M,

  thanks for your answer.

  Actually I need a 1V resolution (@arround 250V) and a measurement each 1 or 2 sec. The values are 'clipped at top range'. So I get a straight red line :-(

  I need to give an evidence to the regulator that the tension does not reach 253V... so it needs to be quite accurate....

  Is there a way to download a file with all measurements ?

  thanks for your help...

  Hi Ferdinand d'Aspremont Lynden,

  If you are having clipping issues in Logger mode, you will need to select a higher volts/div or zoom out the graph to see the full reading. The Logger doesn't autorange.

  I hope this helps you to get the measurements you need!

  Also, you can save your Logger readings and export them under the 'History' area. You can save them to your phone or share them via email or social media, and will be exported in .csv format.
