ATORCH DL24 Electronic Load / Capacity Tester Unboxing and Usage

There are some very nice and inexpensive load and capacity testing devices available out of China. These units are packed with features and very capable for hobbyist. The instruction manual may be a little on the light side though.
A second video covers the configuration and calibration in detail. • ATORCH DL24 Configurat...

Hi, have you ever meet UREG error message at your Atorch DL24? I staked into the problem with this message, as well, as my DL24 sensing 20 V input voltage, as "2.0V", not 20 Volts. Thank you in advance !

It could be that you triggered a voltage calibration. There are two options on the settings screen for voltage calibration, one for zero volts and one for 30 volts. For the zero volt calibration you need to disconnect all inputs and trigger the calibration for the 30V calibration you need to have a 30V reference voltage source and trigger the calibration. Let me know if you need more info.

@@jtechlabs6037 Thanks a lot for support, much appreciated ! I’ll try to recalibrate this device, it’s not so simple, due to partially Chinese menus, but anyhow, you show me the way to dig for solution. Have a nice day !

@@jtechlabs6037 Thank you a lot for information, I think, that you're totally right. I'll try to provide recalibration now, and will let you to know about the results. Thank you a lot for given support !

I just posted a video that shows how to calibrate the voltage and the current.

No need for those thick wires for the sense wires as almost no current runs through them. Nothing theoretical about precision, the voltage measured by 4 wires takes into account the voltage drop in the wires making it a much more precise instrument. Standard in any pro power supply and any other equipment where precise measurements are required as voltage otherwise will depend on the current drawn, even risking overcharging battery/cells if wires are way to thin or faulty.
