The present version of the originally proposed technique does not incorporate a completely sealed passage for the test oil from the Lower End Cap of the Depositor Assembly to the gear pump. As a consequence there are occasional very high deposits that occur that cannot be duplicated. Moreover, there is an opportunity to improve precision by returning to complete sealing.
