200tdi VDO tach adjustment?

Anyone know how to get a rough idea of what the engine is running at on a 200?
I've messed with the 3 toggles on the back of the tach, but still can't seem to get it right.
I thought I had the idle right(800-900rpms) but it seems to climb very fast. Is there a way to tell the rpm without the tach

There is a screw on the side for fine adjustment. The switches are just for very coarse adjustments. Assume idle is 700 rpm to get in the ballpark.

You can check fairly well if you know your gearing and and use a GPS for speed. To get exact setting a laser tachometer is the easiest way. They are quite cheap.
