ATORCH DL24 Configuration and Calibration

The DL 24 from ATORCH is a feature packed electronic load and capacity tester for hobbyists. In this video on review the configuration and more importantly calibration features of the unit and show how to calibrate voltage and current.
This is the second video dealing with the DL24.
The first reviews basic functionality.

I have that one on the right @ 16:48. Do you have a video on that one? I bought it to test a 100 amp battery but it just came today so have not used it yet. The one I got from Amazon is identical but with the brand name of "MakerHawk"

I haven't done a vid for it yet, but I will prioritize it I first saw it on ProjectFarm. One of the key differences is that it allows for very fine control over the load with a simpler control structure of the knobs.

Thanks i get the point but for dl24ew there is no dedicated port to plug the load. There is d, s etc. What are we gonna do?

[@jtechlabs6037]

Unfortunately, I don't have a DL24EW. I had a look at some product listings and they did not seem to have the same calibration option.

@@jtechlabs6037 it is d for + and s for -

how do i get it to work with a powerbannk

[@jtechlabs6037]

Have a look at this video czcams.com/video/HjY95-U7_4U/video.html
It shows a 12V battery. For a power bank you will likely have 5V and set the current to a typical load like 3A or 3.5A. I would suggest setting the cutoff voltage to 3V.

so when you have bought one, you need to buy a 2nd to calibrate the first, but the 2nd one wont be calibrated so you need to buy a third, but the third wont be calibrated....
Maybe we just need to use the calibrate out socket to a 12v 55w car headlight bulb in series with a multimeter set to amps, then adjust input voltage to change brightness of bulb/meter reading for 3amps and press the set button..

[@jtechlabs6037]

You can absolutely use any known 3A load

[@dv5809]

You can simply short-circuit current output and use your power supply connected to the load's input to get 3A
