Users can now use the mouse wheel to scroll up and down through the rows in the table view, making it easier to locate the row you need. For larger captures, you can now also use a vertical scroll bar to quickly scroll through days or weeks of tabulated data in seconds.
In this release, we've added support for the PicoScope 4444 differential oscilloscope which includes support for the PicoD9 intelligent probe interface and all of the PicoD9 probes and adaptors. Now you can measure current and voltage for slower sampling applications, for example long term (parasitic) battery drain.
Various advanced oscilloscope features are disabled; including triggering, capture memory. Sampling speeds are limited to 1 kS/s per channel.
One known issue is that there is no way to zero the current probes, so it's possible for small offsets to appear on your measurements. This is because PicoLog uses streaming mode which must be always on, and to zero a probe would require us to stop sampling on that device altogether. You would be able to make a one-off alteration that would affect the whole capture using channel scaling, this is possible by subtracting the initial offset value observed (without the clamp around the conductor) from the channel data. This method does not protect against thermal drift or drift over time. So for this reason, it is not possible for us to guarantee the accuracy of the current probes.
You asked, we listened!
We've added new capture modes to PicoLog 6. In previous version, the only option was infinite capture length. Of course, not everyone wants to capture indefinitely, so this added feature allows you to specify how long you want the capture to last, in minutes, hours or days. You then decide what happens when the capture time reaches the time limit; either continue capturing and overwrite the stored data (circular buffer), or stop the capture.
With added support for the PicoScope 4444 oscilloscope, we've extended the maximum zoom factor by 4 times, making it easier to see 50 Hz mains waveforms close up.
As capture sizes and number of devices configured in a PicoLog 6 config increase, we needed to switch to a different backend database structure. The changes are all behind the scenes, so you can start using it right away. You will need to delete your existing configuration and capture data buffer to start using it.
This change has no bearing on the saved .picolog file format, it only affects the database we use for storing live acquisition data..
