R&S NGE100 voltage jumping around

[YetAnotherTechie]

I also noticed that if I move the voltage up and down with the output turned off, the output voltage shows a negative step of about 450mV for about half a second, which is crazy.

Can confirm, V 1.54
On channel 1 mine does it from 4.10 to 4.00 and on channels 2 and 3 it's from 4.00 to 3.90.
So going back to beginning of the thread, it seems this is a bug related to something internal switching around the 4V setpoint.

Hello,

i try to use a NGE103B FW1.57 to aquire charging curves of batteries.
Therefore the supply is in constant current mode until the battery is nearly full.
When in CC mode the output voltage is jumping up in approx. 100mV steps and not increasing smoothly as expected.
So the charging curves are completly useless.
Is this a common problem with the regulation of this type of supply, because i cant find anything in the datasheet hinting at such a poor current regulation?

Thanks
