The manual for the unit will show some examples of the diplay appearance
while changing the settings, but you might be able to select the correct
settings by using the following steps (which are from notes I kept from the
manual of the same unit).
If I had a manual, I'd send you a copy. Maybe someone else can.

If you have compatible scales connected, you can probably come up with the
correct settings by experimentation or trial & error.

- Turn Power on
- Push/hold A/I
= one of the Setup screens wil be displayed
- Release A/I
= unit is now in Setup Mode

- Press Rad/Dia to advance to the desired screen (field)
- Press Reset to change parameter setting
- Press Rad/Dia to advance to desired screen (field)
- Press Reset to change another setting
- Exit Setup Mode (saves selected setting(s), by pressing A/I

Here is something I should be able to figure out but can’t. I have a
Sargon model 652 DRO now on my lathe. (It has no numeric key pad). How
do I zero this thing so I can get a direct radius or diameter reading
for a bar I would be turning?

The radius is off by a factor of 2 and the diameter is off by a factor
of 4.

TIA
