Hello - After downloading and opening the .csv file of EMF data, I notice that many of the lines are missing a timestamp. The intervals of lines without timestamps are also of varying sizes, so there is no way to accurately assign a timestamp to each. Anyone else have this problem? Is this an issue with the software? I'm looking to plot this data vs time, so I'm also open to any templates or macros folks have been using.

Hi RungeKutta, can you send me your CSV file via email or take screenshot and post here? What version of the software are you using?

Here is screenshot showing how the Date and Time is stamped at random invervals. It also doesn't seem to go in order, so it's not possible to accurately plot. The device says Revision 2.2.

Did you download the EMF PRO v3.54 online? This is the latest version and should have timestamp in between.

Regarding your data, it might have been that the missing timestamps are when you turned off your device. It puts a timestamp everytime you turn it ON, and also every 3 minutes after device in powered ON.

Thanks for the reply! I'll try using the V3.54 software and see what happens. Here's another screenshot of some typical data. There are upwards of 80K lines and the vast majority do not have timestamps.

The timestamps goes like this:
e.g.

12:00:00
..missing
..missing
.
.
.
12:03:00

the missing ones are 12:00:01 up to 12:02:59
