Ok, here is an answer, engine warm to the touch.
Page 15.16 of the Bentley says engine oil temp 30 degree C (86 F) for
diesel engine compression test.
Page 15.20 says oil temp 30 degrees C (86 F) for waterboxer compression
tests.

Presumably, you should run the engine for a minute or 2, wait a couple
minutes, pull all the plugs, do the test. If the plugs burn your
fingers, wait longer.
