Hi, I have not got 5.13.9 to try out.
What I can say is that I would choose 100ms as your scan time instead of 1 second. You should really have your scan time to be less than you sampling interval.
It could be that some default settings in PicoLog recorder changed in later release. There is parameter callled QuickSampleMS which is set to 1000ms by default, you can reduce that if you want a bigger scan time. You can achieve this by modifying your plw.ini file
This can be found under:
C:\Documents and Settings\USER\Local Settings\Application Data\Pico Technology
where USER denotes your login name.
One of the folders will have the plw.ini file.
Once you opened the file add the following lines
where x denotes your ms.
Warning: reducing this will significantly slow down the sampling speed of some ADC units by preventing the Quick sample mode from being active at sampling intervals up to 1000 ms
Hope this helps.
