Actually, the voltage depends heavily on the instrument used, there is
quite some variation.
Some values I got a while ago:
Fluke 45:
open circuit voltage: 1.5V
display in ohms range on small signal diode: 260k
test current into ammeter: 0.8mA
Agilent/HP 34401:
O/C voltage: 5V (yes, five)
test current: 1mA
reading on diode: 40k
Fluke 79III:
O/C: 0,626V
test current 0.4mA
reading on diode: 1.3M
That said, I agree that the chance to damage anything is almost zero.
