ET5410 Electronic load tester issue

[da9el84]

Hey guys,

I've seen some of you also buying this unit, but I cannot for the life of me figure out what setting I am doing wrong.

I go to battery test, choose CC, select 40 A and cut-off at 2.5v. Press on/off, the screen blinks, the blue dot on the left turns red, sometimes it says "unreg" in the bottom left corner and nothing happens. If I change over to constant resistance instance and do 10ohm, the test will start when I click on/off.



I've also tried setting the levels to 3.2v, 3.0v and then 2.5v with various amp levels, didn't work either.


The manual is pretty useless and doesn't explain the various points under each functionality that the device can do...

Hmm, messing around some more I got it working by turning down the amps. Seems like it won't start the test if the amps is higher than 10.............

I think I found the issue. I changed my wires to thick 25mm2 and pumped the amps up to 40 again and now it works. The device must have sensed the wires couldn't support the amps.
