Oil pressure psi.

Oil pressure psi.
Does anyone know what the idleing psi for oil on a 90 7.3? A couple days ago the oil pressure gauge started acting funny so I replaced the sending unit, and added a mechanical gauge. After the motor warms up and oil pressure on the dash is good, but on the mechanical gauge it drops to 10psi. Drive down the road and the pressure goes up like it should. Is 10psi idling right or is it too low?
