Rigol DL3021 Programmable DC Electronic Load (Single Channel, 150V/40A/15kHz 200W)

Not ideal for low current

3.0

Purchased this DL3021 for both higher and low power applications. I work on several projects that have current usage under 10mA. So the first thing I did was power up the load, connect it to my power supply at 5v, type in 600 ohms constant resistance (~8.3mA) and turn on the tap. And guess what? Nothing happened, it was like the load was off. It starts to work at 9-10ma and is stable after about 12ma. I called Rigol and they confirmed this is as designed. The load works great at higher power but this was a deal breaker for me and I ended up returning the unit a couple of days later and getting a different brand not sold at TEquipent. Oh, and as other people have mentioned in their reviews, the UI is annoying but usable. All the UI issues mentioned are still present.
