shown as being representative of the fact that device 12 can have several low side terminals 54 and that the apparatus 10 is capable of handling this plurality of low side terminals 54 further it will be seen that the current limiter 58 is connected via a line 60 to current monitor 22 a voltage monitor 62 is connected via a line 64 to the device 12 and is provided for accurate sensing of load voltages on the device 12 more specifically the voltage monitor 62 is attached at an appropriate high side terminal 18 39 to minimize or eliminate substantial errors which could otherwise be introduced by the impedance in major current carrying leads for purposes of the present invention voltage monitor 62 can be of a type well known in the art such as a kelvin terminal it is to be appreciated that the voltage monitor 62 need not be operated continuously instead voltage monitor 62 can be controlled by processor 26 and selectively activated according to the particular desires of the operator and the requirements of the test regime a key aspect of the apparatus 10 of the present invention is that the processor 26 is able to control all of the components as mentioned above processor 26 is directly connected to power source 14 via the line connector 24 additionally processor 26 is directly connected to i the current limiters 58 via line connector 66 ii the voltage monitors 62 via line connector 68 and iii the current monitors 22 via line connector 70 for purposes.
