mrprecision:
Thanks for the feedback, so you are happy with my tool, or do you have ideas for improvements?

kleiner Rainer:
The tool is ideally suited for my purposes, logging data like charging/discharging curves of batteries. One little thing that comes to mind is a button to turn off the backlight during very long logging sessions (maybe via the POWER:BACKlight command?), and, if you are extremely bored, a way to set amplitude and time remotely.

Here the latest logging of a car battery being charged by an intelligent charger:



The two voltage drops to 12.5V are load tests, then you can see the charger starting with 3.8A, then at 13.9V dropping to 3A, then at 14.25V dropping to 800mA, and at 14.52V switching to trickle charge/standby.

Again, thank you for a well-made and useful tool.

Greetings,

Rainer

I think that there is no possibility to switch off backlight when is connected to AC with serial commands. The trick is disconnect the AC adapter and when backlight is off, connect AC againt. If you dont touch any key light will remain off.

I have made a Video how to replace the CCFL Tube with a LED strip. The audio comments are in German.

I followed the video as best I can without understanding the German. If you could share a few specific details-
1) source for LED strip
2) info on voltage converter
3) details on the connections for the voltage converter.

As I remember the wires are not colorcoded which is a great pain.

I have two THX720's and they are both dim with the stock light, even with a new tube. I'm ready to do this.
