Hi group,
Is there a bigger User's Manual for the Xprototlab other that what I found here?
Can I use the device to monitor a DC voltage source?? In other words, can I probe the value on an ongoing basis? Say every second?
 

A printable manual is on my to-do list. I also need to update it since I have added more features recently.
Yes, you can continuosly monitor a voltage using the "meter mode", it will work just like a volt meter.
