Per the 124 Maintenance CD for the 300TD with the 6 cylinder 603 Turbo, the compression testor screws in the injection port after the injector is removed. They specify the cylinder must go through at least 9 revolutions. New compression is 26-32 bar or 29-35 bar, depending on which compresion recorder is used. I do not understand the difference in the tool, since pressure is pressure, but this is what the book says. I do not have any of these special tools, but have used one on a VW diesel many years ago. The specifed wear limit is ~18 bar (no difference between tools), and all cylinders must be within 3 bar. One bar equals 1 atmoshere which is 14.7 psi. The specs from your car may vary a little. Good luck.
