However if you are using a mobile phone or tablet to view our website it may not be visible.
To this end I have copied in a link to the electronic version of the instructions as well as a brief summary of the requested information below for your convenience.
The lowest output voltage would be zero, as in no output at all.
The DC voltage can be raised in increments of 0.1v so you can set any value between zero and the maximum in increments of 0.1v
0.1v, 0.2v, 0.3v, ..... 1.0v, 1.1v, 1.2v .. etc
