if the process determines at step 415 that a pre determined minimum voltage is present at the point contact the process proceeds to step 420 where the process applies an incremental increase to the current load on the point contact the process then proceeds to step 430 where the process measures the voltage at the point contact and determines if the voltage continues to exceed the pre determined minimum voltage if so the process loops back to step 420 where the current load is increased incrementally the loop of process steps 420 and 430 continue until such time as step 430 determines that the voltage at the point contact no longer exceeds the pre determined minimum voltage at which time the process proceeds to step 440 at step 440 the process measures the current being drawn from the measured circuit and stores the value of the measured current load in a memory and the process drops the current load on the point contact to zero the process then proceeds to step 450 where the stored value of the measured current load is displayed at step 460 the process clears the stored value of the measured current load and the process loops back to step 401 and the process 400 repeats until an adequate voltage is no longer present at the measured point contact in another embodiment of the present invention the process 400 may modified to store each voltage.
