High current tester modding
#11
Yes, the discharge stop voltage ("sv") feature works perfectly and - crucially - the load supports 4-wire measurement (unlike the DL24 you lamented in another thread here), so it stops at the actual battery voltage measured through the dedicated voltage sense wires, not the end-of-load-wire voltage (with 2-wires).  I've used it many times without issue. 

For example, here's a test I did just now using 4-wire hookup. I discharged a NiMH cell at 1A with 1.20V stop voltage and my DMM claims it stopped at 1.2013V (= min battery voltage measured by DMM in min/max mode, 5 measurements/sec). As I said, the factory calibration is great on these units - a pleasant surprise at a $25 price point.
