As @Street has mentioned, 10 on the resistance isn't great (although some gym ergs are so full of dust, 10 on the side can give you a sensible DF)
Whenever you get on an erg (unless its the same one!) you should go into More Options -> Display Drag Factor. As mentioned above it depends on height/weight/sex. BR guidance for testing sets DF as 138 for heavyweight men,and I believe 130 for heavyweight women. Lightweight, under 75kg for men and under 61.5kg for women, is ~123 and ~118 respectively.
I tend to do all my longer ergs at about 128 (I'm 6ft 1 and ~94kg) but testing is done at 138.
A high DF is more likely to cause you to injure yourself as it increases the strain on your back in the drive phase, hence why our long ergs are done at a lower DF!
Probably more info than you wanted, but that's the reasoning behind it, and why I sigh when walking into a gym and seeing all the ergs on 10 (sorry @Martynt74 )
