## Questions & Answers

**Q: Is the the cv programming resolution (1mv) at 0-15v the same for dl3021 and dl3201a?**
A: The readback voltage is  0.1mv for both DL3021 and DL3021A. I would highly recommend DL3021A, since DL3021A installed all the options.

**Q: Can this be used as a dc power supply?**
A: This is an electronic load, it cannot be used as a power supply.

**Q: Can this be used as a DC power supply ?**
A: No, it is a load, which means it removes power. It does not have power supply capabilities.

**Q: Does this come with a Calibration certificate?**
A: Yes, the instrument will come with a calibration certificate from the factory.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent unit for testing batteries
*by N***D on April 30, 2023*

With the built in capability to test batteries, this made the process extremely easy. Had 25 100Ah LiFePo batteries to test and the DL3021 made the job quick and easy. Wish there was a model with a higher load capacity, but am very happy with the quality of the unit and its ability to test various scenarios. I would recommend the RIGOL DL3021.

### ⭐⭐⭐⭐⭐ Works very well. Exceeds expectations.
*by M***H on March 22, 2024*

Makes testing bench equipment and PCBs easier.

### ⭐⭐⭐⭐⭐ Works well
*by W***T on March 22, 2019*

Voltage readout to tenth milivolt (0.0001v) and it matches exactly a 4 digit siglent bench multimeter (0.001v). It has banana ports for separate voltage probe. Will read high when drawing current otherwise by maybe half a significant digit. Good feature.Only records mAh when using "battery" function, not aure why you wouldnt want that available all the time. Short function is handy. Lots of bells and whistles to go along with the main operation modes.Menus are no problem, control layout is streight forward, coltrols themselves are good. Wish the terminal posts had banana plug option but not a big deal.One annoying thing is when you enter any menu or even change the display to show a graph over time instead of a momentary reading it aborts the current operation and you have to start again. Annoying because if your tracking voltage sag or something the display switch will mess that up.All around good tool. Works well for my needs.Graph display is nice but its not very flexible. Siglent has better graphing on their multimeters. Then again its lan capable so you can just graph on a computer uf its a necessity.Overall no real problems, good purchase.
