Finally got all my cables in order and started playing with the software. Has anybody been able to get Discharge software to actually turn off load when end voltage is reached? I tried it quickly with a power supply and it just kept going. On the second thought, i don't see any "OK" or the like button to confirm that I entered the number. Ideas? "Smoking gun" picture is attached

I've used it quite a bit since I got it, however the software is just short of garbage.

Use the "discharge" software only to collect data that it then ports to excel.  Other that turning the test ON, do not control the Array with its  'discharge' or the main software; I found them both unreliable, the discharge one is the least worst of the two.  You may have to press the buttons several times to get a response and this is not related to the baud rate either.  Check the status lights of the USB-TTL interface to insure data is going each way.

You'll have to experiment with the data capture rate to find the best for you if you want lots of data points, I think 100ms/point is the limit for practical collection.  Its fairly reliable at 1sec.

When running and collecting data confirm  status not with the PC software but on the Array unit LCD.

Set your shutdown voltage, or any programmed parameters you wish, through the Array unit itself. If you use the PC software, press self control to reactivate the Array keyboard.  I can do pretty much everything through it, the firmware of the eload is reliable.

That's pretty much what I've been doing. Might have to get off my rear end and write something less sucky for general use :)

If you write new stuff, I'd be happy to test it for you, me alas, no time.  One user wrote an extensive suite for it to suggest the hardware is stable to write a good application.

and used that design, an array of 10 array loads working together, in his reviews:

Just ran a discharge test on a replacement cordless phone battery ;) All went well and it stopped exactly at the voltage set as a minimum input. Their stupid logger crashes though when trying to actually save data. Yep, writing own may just be the answer.  I'll post about it on the EEVblog once I get around to that
