Description: TITLE DEVICE FOR AUTOMATICALLY ASCERTAINING CAPACITANCE, DISSIPATION FACTOR AND INSULATION RESISTANCE OF A PLURALITY OF CAPACITORS BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to automated test equipment for the testing of capacitors. Description of the Prior Art Capacitors manufactured using a film dielectric are typically characterized by the same electrical parameters as are ceramic or electrolytic capacitors. Representative of such parameters used to characterize film dielectric capacitors are capacitance, insulation resistance (i.e., leakage current), and dissipation factor. These are the parameters typically tested in order to insure that the manufacturing process produces devices that meet acceptable specified limits. Individual pieces of test equipment are available for testing each of these various parameters. However, in order to obtain statistically significant results a large number of capacitors should be tested. Testing capacitors according to present industry practice is a time-consuming and labor intensive process. To effect such testing each capacitor is presently individually connected in turn to each piece of test apparatus and the appropriate test run on that apparatus. Since the testing of all of the capacitors should be effected under substantially identical test conditions, such as temperature and humidity, it is difficult to guarantee that such will be the case when a large number of capacitors are individually tested. Accordingly, it is believed advantageous to provide an apparatus which will automatically test each of a plurality of capacitor samples for each of a predetermined number of parameters under substantially identical test conditions. SUMMARY OF THE INVENTION The present invention relates to an apparatus for automatically measuring characteristics, such as capacitance, dissipation factor and insulation resistance, of each one of a plurality of capacitors. The apparatus includes a predetermined number of test fixtures, each test fixture being adapted to receive one of the capacitors to be tested, and a plurality of measurement devices for measuring various parameters. A relay matrix, having a plurality of relays therein, is connected such that each test fixture may be connected to one of the measurement devices and to a high voltage source of electrical potential. Also included in the test apparatus is means for energizing predetermined ones of the relays in accordance with a predetermined sequence thereby to connect the capacitor associated with each relay to the desired measurement device. Control means is provided for asserting the measurement devices and for controlling the output of the voltage source to apply a predetermined high voltage to each capacitor connected to the source by the energization of a relay. The apparatus further includes recording means associated with the measurement devices for recording the measured values of the capacitor. In the preferred instance the energizing means, the control means, and the recording means are implemented using a digital computer operating in accordance with a program. Each test fixture is configured from a socket having a body with a first and a second group of receptacles disposed in the body. Each group contains at least one receptacle. A first lead on each capacitor being tested _is receivable by a receptacle in the first group of receptacles and a second lead on the capacitor is receivable by a receptacle in the second group. The first receptacle is connected to a first contact set and the second receptacle is connected to a second contact set of the relay associated with the test fixture.

DETAILED DESCRIPTION OF THE INVENTION Throughout the following detailed description similar reference characters refer to similar elements in all figures of the drawings. ■ >* With referenQe.-to Figure 1 shown is a system block diagram of an automatic capacitor testing apparatus in accordance with the present invention for automatically measuring various predetermined parameters of each of a plurality of capacitors. The testing apparatus is generally indicated by reference character 10. The parameters able to be tested include capacitance, insulation resistance (i.e., leakage current), and dissipation factor. The testing apparatus 10 includes a controllable high voltage source 12 of electrical potential, an N position capacitor holding assembly 16, an interface 18, a combination inductance, capacitance and resistance (LCR) measurement device 20, a picoampere current measurement device 22, temperature measuring device 24 and a programmable controller 26. The interface 18 is implemented using a card cage such as that manufactured by Hewlett Packard Inc., Palo Alto, California and sold as the model number HP 6942A multϊprogrammer interface. Suitable for use as the controller 26 is the device manufactured by Hewlett Packard Inc., Palo Alto, California and sold under model number HP 9826. The combination inductance, capacitance and resistance (LCR) device 20 is preferably implemented using a Hewlett Packard HP 4274A instrument. The picoampere current measuring device 22 is preferably a Hewlett Packard HP 4140B instrument. The temperature measuring device 24 is preferably implemented using a device manufactured by John Fluke Manufacturing Co, Everett, Washington, and sold under model number 2170A. If desired the assembly 16 may be thermally insulated and/or temperature controlled to insure a particular predetermined temperature under which the capacitors are to be tested. The source 12 is connected by a high voltage input line 32 and a high voltage ground line 34 to the capacitor holding assembly 16. The lines 32 and 34 are implemented as a coaxial cable. The use of a coaxial cable throughout the apparatus 10 is preferred to insure immunity to electrical noise. Suitable for use as the s irce 12 is a high vojtage power supply such as that manufactured and sold by Bertan Company of Syosset, New York and sold as model number 205A-01R. The assembly 16 contains an interconnection network generally indicated by reference numeral 30 and a predetermined number N of test fixtures 38-1 through 38-N. As used herein, high voltage is meant to denote dc voltages up to one thousand (1000) volts. Disposed in the holding assembly 16 in temperature sensing proximity to the fixtures 38 Is a temperature probe 24P connected to the temperature measuring instrument 24 over a line 24L. In the preferred implementation the probe 24P and the line 24L are provided as a part of the instrument 24, but it should be appreciated that a separate probe or probes may be used to measure the temperature of the fixtures and to provide a signal representing the same to the instrument over a suitable interconnection line(s). .As may be understood from Figure 2, the lines 32 and 34 are connected by a coaxial jack 40, through a relay 98, to a high rail 42 and a common potential point 94. A high resistance (on the order of fifty thousand ohms) and high wattage (on the order of twenty five watts) resistor 46 is connected in series between jack 40 and the high rail 42 to protect the power supply 12. A door interlock switch 48 and a door actuated rail shorting switch 50 are both physically mounted within a metal enclosure provided for the capacitor holding assembly 16. A portion of the enclosure is diagrammatically indicated by the reference character E. The enclosure E is provided with an access door diagrammatically indicated by the reference character D. The enclosure E having the door D therein may be formed by any suitable construction well within the skill of the art or any commercially available electrical box may be used. The interlock switch 48 is implemented using a pair of microswitches 48A, 48B, from which emanate a pair of lines 48L. The lines 48L are connected to a distribution board 52(see Figure 1). The output 54 from the board 52 is connected to the enable terminal of the supply 12. Suitable for use as the <& ■ x microswitches 48 are devices manufactured by Omron Corp., of Schaumburg, Illinois and sold as model number S-5HL12-IAS-K. The rail shorting switch 50 is formed by a pair of contacts 50X, 50Y that are bridged by a contact disc 50D. The disc 50D is connected to a spring loaded plunger 50P that physically engages the door D of the enclosure E. When the door D is closed the plunger 50P causes the disc 50D to disengage from the contacts 50X, 50Y. When the door D is opened switches 48 open, thereby disabling the high voltage supply 12 via the board 52 and the line 54 therefrom. .Also, upon further opening of the door D the disc 50D engages the contacts 50X, 50Y and shorts the high rail 42 to chassis ground on enclosure E to prevent an electrical shock hazard to the operator. Figure 2 depicts the disc 50D in the position it occupies relative to the contacts 50X, 50Y when the door D is closed. As is seen in Figure 2 each test fixture 38 is connected between the high rail 42 and the low rail 44. Each test fixture 38 is adapted to receive one of the capacitors to be tested. Each fixture 38 includes a socket assembly, generally indicated by reference character 60, and a relay 66. Each relay 66 includes two pairs of contacts 66C1 and 66C2 and an actuating coil 66S. The coil 66S of each relay 66 is connected over lines 68 extending to the interface 18 as will be described. Suitable for use as the relays 66 are those high insulation resistance, flying lead relays manufactured by Douglas Randall Company of Pawcatuck, Connecticut as model number 379525. As seen in Figures 3A through 3C the socket assembly 60 physically comprises a body portion 70 formed of an insulating material such as polyamide-imide, manufactured by Amoco Chemical Co. under the trademark Torlon. The body portion 70 has a predetermined number of receptacles 72 arranged therein. In the preferred instance the receptacles 72 are arranged in two groupings indicated by the reference characters 72A and 72B. In the preferred case the socket assembly 60 is implemented using a zero insertion force, dual in line planar device such as that manufactured and sold by Textool Incorporated, Irving, Texas, under model number 240-3346-00-2402. The assembly contains dual rows of adjacent receptacles, and thus may be used to define a pair of socket assemblies. The assembly is modified by removing several of the receptacles and associated pins and wiring together the remaining pins to define the receptacle groupings discussed above. This increases the electrical isolation of the receptacles in each grouping. The openings from which the receptacles have been removed are filled with a nonconducting polymeric material such as epoxy. The interconnection network 30 includes a dedicated relay arrangement adapted to interconnect each of the test devices to the high and low rails 42 and 44, respectively. In general, in the preferred embodiment illustrated the network 30 includes a first relay arrangement 80 that interconnects the LCR instrument 20 to the rails 42 and 44 and a second relay arrangement 85 that interconnects both the measurement and the voltage source terminals of the picoampere instrument 22 to the rails 42 and 44 and a third relay arrangement 86 that interconnects only the measurement terminals of the picoampere instrument 22 and the separate external high voltage source 12 to the rails 42 and 44. In the preferred embodiment illustrated in Figure 2 the first relay arrangement 80 is implemented using a pair of double pole, normally open relays 81, 82, each identical to the relay 66. The relay 81 includes a dual contact set 81C1, 81C2 and an actuating coil 81S while the relay 82 includes a dual contact set 82C1, 82C2 and an actuating coil 82S. The pair of relays 81, 82 is required to implement the first relay arrangement 80 since the particular measuring instrument (the LCR instrument 20) has four measuring terminals. One side of the contacts of the relays 81, 82 of the first relay arrangement 80 is connected to the instrument 20 over a group 83 of four lines 83L-1, 83L-2, 83L-3 and 83L-4. Each of the lines 83L-1, 83L-2, 83L-3 and 83L-4 is preferably implemented using a coaxial cable. The other side of the contacts 81 Cl and 81C2 of the relay 81 is connected to the high rail 42 over lines 84L-1 and 84L-2. The other side of the contacts 82C1 and 82C2 of the relay 82 is connected to the low rail 44 over lines 84L- 3 and 84L-4. The coils of the relays 81, 82 are wired in parallel and connect to the interface 18 over a pair of control lines 80L. The second and third relay arrangements 85 and 86 are each implemented using a pair of double pole, normally open relays 87, 88. and 87, 98, respectively, each identical to the relay 81. The relay 87 includes a dual contact set 87C1, 87C2 and an actuating coil 87S while the relay 88 includes a dual contact set 88C1, 88C2 and an actuating coil 88S. The pair of relays 87, 88 is required to implement the second relay arrangement 85 since the particular measuring instrument (the picoampere measuring instrument 22), when using its internal voltage source, has four required connections, two measurement terminals and two voltage terminals. One side of the contacts of the relays 87, 88 of the second relay arrangement 85 is connected to the instrument 22 over a group 90 of four lines 90L1, 90L2, 90L3 and 90L4. The lines 90L1 and 90L2 are preferably implemented as the two inner conductors of a triaxial cable. The lines 90L3 and 90L4 are preferably implemented as the center conductor and the shield of a coaxial cable. A high resistance (on the order of fifty thousand ohms) and high wattage (on the order of twenty five watts) resistor 91 is connected in series between line 90L3 and the high rail 42 to protect the internal voltage source of picoampere instrument 22. The other side of the contact 87C1 of the relay 87 is connected to the low rail 44 over a line 92L1. The other side of the contact 88C1 of the relay 88 is connected to the high rail 42 over a line 92L3. The other side of the contacts 87C2 and 88C2 of the relays 87, 88 are connected to a point of common potential 94. The coils of the relays 87, 88 each connect to the interface 18 over pairs of control lines 87L, 88L. The third relay arrangement 86 is comprised of the pair of relays 87, 98 (each identical to the relay 81). The relay 98 includes a dual contact sel 98C1, 98C2 and an actuating coil 98S. The pair of relays 87, 98 is required to implement the third relay arrangement 86 since the particular measuring instrument (the picoampere measuring instrument 22), when used with a separate external voltage source, has two required connections (the two measurement terminals) and the separate external voltage source has two required connections. The coil 98S of the relay 98 is connected to the interface 18 over a pair of control lines 98L. One side of the contact 98C1 is connected to the high rail 42. The other side of the contact 98C1 is connected to the supply 12 over the line 32. The first side of the contact 98C2 is connected to the point of common potential 94. The second side of the contact 98C2 is connected to the supply 12 over the line 34. The interconnection network 30 further includes a discharge relay arrangement 102 comprising a relay 103 identical to the relay 81. The relay 103 includes a dual contact set 103C1, 103C2 and an actuating coil 103S. The coil 103S of the relay 103 is connected to the interface 18 over a pair of control lines 103L. One side of the contact 103C1 is connected to the high rail 42. The other side of the contact 103C1 is connected in series with a high resistance (on the order of fifty thousand ohms) and high wattage (on the order of twenty five watts) resistor 106 to chassis ground of enclosure E. One side of the contact 103C2 is connected to the low rail 44. The other side of the contact 103C2 is connected in series with another high resistance (on the order of fifty thousand ohms) and high wattage (on the order of twenty five watts) resistor 108 to chassis ground of enclosure E. The discharge relay arrangement 102 provides means to dissipate stored energy remaining across a capacitor in the test fixture and thus provides capacitor discharge means connected across the fixtures for discharging a capacitor previously connected to either the internal high voltage source of the picoampere instrument 22 or the separate external high voltage source 12. The interconnection arrangement above described for interconnecting the particular test instrument to the holding assembly 16 is necessary to permit accurate measurement by the instrument of the desired parameter. The shielding of the cables. the interconnection of their shields to a common potential, and the very high insulation resistance (on the order of hundreds of thousands of megohms) of the relays used allows an accurate measurement to be made. The key point to note is that even though the capacitor being tested is physically remote from the instrument, in accordance with the present invention it appears as if it is electrically proximal to the instrument. The relays in the capacitor holding assembly 16 together with the relays in the interconnection network 30 cooperate to form a relay matrix connected between the test fixtures 38 and the plurality of measurement devices 20, 22 (and, when used in conjunction with the test instrument 22, as will be developed, the high voltage supply 12). Mounted in the interface 18 is a relay output control arrangement generally indicated by reference character 110. The relay output control 110 includes, in the preferred case, one or more output modules such as those manufactured by Hewlett Packard Inc., Palo Alto, California and sold under model number 69730A. The relay control 110 is connected to the relay control lines 68 emanating from the coils of each of the relays 66 respectively disposed in each of the test fixtures 38 and to the relay control lines 80L, 87L, 88L, 98L and 103L. The relay output control 110 is connected to an internal bus 114. The bus 114 is connected through an interface 116 and over a communications bus 120 to the programmable controller 26. The communications bus 120 may be implemented in accordance with IEEE Standard 488. The controller 26 and the relay output control 110 act together to assert the coil 66S associated with a given one of the relays 66 by sending an enabling signal over the control lines 68 associated with the predetermined relay 66. The controller 26 and the relay output control 110 also act-together to assert one or more of the paired coils 8 IS, 82S, the coils 87S and 88S, and the coils 87S and 98S respectively associated with a given one or more of their associated relays by sending an enabling signal over the appropriate respective control lines 80L, 87L, 88L and 98L. Thus, the controller 26 and the relay output control 1 10 together define means for energizing predetermined combinations of the relays in the relay matrix in accordance with a predetermined sequence thereby to connect a capacitor mounted in predetermined ones of the test fixtures with predetermined ones of the measurement devices. The controller 26 and the relay output control 110 additionally act together to assert the coil 103S associated with the discharge relay 103 by sending an enabling signal over the appropriate control line 103L. .Also mounted in the interface 18 is a digital output module 122. Preferred for use as the digital output module 122 is the device manufactured by Hewlett Packard Inc., Palo Alto, California and sold under model number 69731 A. The output of the module 122 is applied to the high voltage supply 12 over the lines 124. The digital output module 122 is connected to the internal bus 114 and, thus, to the programmable controller 26. In a manner to be described the controller 26 together with the digital output module 122 to define control means for controlling the output of the voltage source 12 to apply a predetermined high voltage. .Also mounted in the interface 18 is a digital input module 126. Preferred for use as the digital input module 126 is the device manufactured by Hewlett Packard and sold under model number 69771A. The input of the module 126 is connected to the temperature measuring instrument 24 over the lines 128. The module 126 is connected to the internal bus 114 and thus to the programmable controller 26. The probe 24P provides means for generating a signal representative of the temperature on the interior of the capacitor holding assembly 16 and, thus, of a capacitor in a test fixture while the the instrument 24, the module 126 anoVthe controller 26 cooperate to define means for recording the temperature. In the embodiment described the value of the temperature is stored in the memory of the controller 26. Of course, any suitable recording device indicated diagrammatically at 26R could be used in conjunction with the controller 26. As an example, the device 26R may take the form of a magnetic media recording device, a hardcopy printer, a plotter and/or a CRT display. The instruments 20 and 22 are interconnected to the controller 26 over the communications bus 120. The operation of the apparatus heretofore set forth will be explained in the context of testing multiple capacitors for various parameters, including, for example, capacitance, dissipation factor and insulation resistance. With reference to the block diagram of the program shown in Figure 4, at 150 the operator initializes the apparatus 10 by energizing the hardware and loading the program defining the test protocol into the controller 26. See pages 20 through 25 of the Appendix at reference character 150. The operator then loads the capacitors to be tested into the appropriate test fixtures 38-1 through 38-N. Not all of the fixtures need be used. The individual capacitors are loaded with one lead of the capacitor inserted into a receptacle in the receptacle group 72A and other lead into a receptacle in receptacle group 72B. The appropriate receptacle in the particular receptacle group is selected based upon the physical size of the capacitor. Once the capacitors are locked in place, the door D of the enclosure surrounding the holding assembly 16 is closed, thus closing the interlock switch 48 and opening the rail shorting switch 50, thereby allowing a voltage to appear across the high rail 42 and the low rail 44. As also shown at 152, the operator provides sample identification and test details. Examples of the former include sample description, capacitor type (metallized film, • film/foil, electrolytic, multilayer ceramic, etc.), film thickness, and testing date. Test detail information includes operator name, job number, starting sample number, total number of samples, and. the number of voltages and the specific voltage levels at which insulation resistance is to be measured. See pages 20 and 25 through 29 of the Appendix at reference character 152. In summary, upon the operator's command, the automatic test sequence begins. The test protocol sequentially discharges all the capacitors to be tested, measures the temperature of the capacitor holding assembly 16, selects a test instrument to be used to make one or more measurements of selected parameters on each capacitor. The capacitors to be tested are then connected sequentially to the selected test instrument, the parameters measured and recorded by the controller. The controller again sequentially discharges all the capacitors. The next test instrument is selected and the capacitors are again connected sequentially, the parameter(s) measured and recorded. This sequence is repeated until all parameters of all capacitors have been recorded. The temperature of the capacitor holding assembly 16 is measured a second time to insure that the temperature has not changed substantially since the testing began. After all parameters have been measured the controller again sequentially discharges all the capacitors. In this way it may be seen that the apparatus in accordance with the present invention automatically tests each of a plurality of capacitor samples for each of a predetermined number of parameters under substantially identical test conditions. As seen at 154 in Figure 4 the discharge relay 103 is asserted under program control to dissipate any residual charge on the capacitor. The coil 103S of the discharge relay 103 is asserted over the line 103L by the control module 110 in response to the controller 26. After a predetermined delay (typically six seconds), to dissipate any remaining charge on the capacitor, the relay 103 is opened. The listing of the routine 154*is set forth at pages 3i and 32 of the Appendix. Calls to the routine 154 are made throughout the program listing and are indicated therein by the dashed suffix following the reference character 154. See, for example, page 20 at reference character 154-1. As also seen at 156 the overall temperature of the capacitor holding assembly 16 is measured by causing the digital input module 126 to read the output of the digital temperature measuring device 24. The listing of the routine 156 is set forth at pages 47 and 48 of the Appendix. Calls to the routine 156 are made throughout the program listing and are indicated therein in the manner similar to that discussed above. See, for example, page 20 at reference character 156-1. In general once the temperature has been measured the controller 26, under program control, selects a predetermined one of the measurement instruments. In the discussion that follows it is assumed that the parameters of capacitance and dissipation factor are measured simultaneously for each selected capacitor. After all capacitors have been measured for these parameters then insulation resistance is measured for each capacitor. The measurement of capacitance and dissipation factor is effected by the controller 26, as generally indicated at 158. See, pages 32 through 34 of the Appendix. See, page 21 for the call to the routine 158, indicated at reference character 158-1. As seen at 158A the LCR instrument 20 is connected to the selected capacitor by causing the relay control module 110 to close the relay arrangement 80. This is effected by the assertion of the relay coils 8 IS and 82S over the line 80L. See, page 33 of the Appendix, at reference character 158A. As seen at 158B, the controller 26, under program control, then selects a predetermined one of the capacitors (corresponding to number of the fixture at which testing is to begin). The desired one of the capacitors is selected by closing the corresponding one of the relays 66-1 through 66-N by the controller 26 sending a command to the relay output control 110 which asserts the appropriate one of the coils 66S in the appropriate relay 66 to connect the fixture between the high and low rails 42 and 44, respectively. See, page 33 of the Appendix, at reference character 158B. From the foregoing it may be appreciated that a predetermined combination of relays in the relay matrix has been energized to connect a predetermined one of the test fixtures with a predetermined one of the measurement devices. The controller 26 then begins the measurement of at least a predetermined one of the parameters of that selected capacitor. As seen at 158C, the particular one of the measurement devices connected to the particular test fixture via the energized relays in the relay matrix is asserted. In the specific instance under discussion the controller 26 sends a command over the bus 120 to the LCR instrument 20 asserting it to simultaneously measure the capacitance and dissipation factor of the selected capacitor. See, page 33 of the Appendix, at reference character 158C. The instrument performs the measurement and reports the results to the controller 26 over the bus 120. See, page 33 of the Appendix, at reference character 158C. As seen at 158D the result is stored in the memory of the controller 26. See, page 33 of the Appendix, at reference character 158D. In the particular LCR meter used, capacitance and dissipation factor are measured simultaneously, although they may be measured separately. Modification of instructions on page 33 of the Appendix, at reference characters 158C and 158D, would be required to do this. As set fort at 158E, once all of the tests being are performed the instrument 20 it is disconnected from the selected capacitor by turning off the relay arrangement 80. See page 33 of the Appendix, at reference character 158E. As seen at the call 154-2, the routine 154 is again performed, thus the discharge relay 103 is again asserted under program control to dissipate any residual charge on the capacitor. See, pages 21 and 31 of the Appendix, at reference characters 154-2 and 154, respectively. As seen at 156-2 the overall temperature of the capacitor holding assembly 16 is again measured by causing the digital input module 126 to read the output of the digital temperature measuring device 24. See, pages 21 and 47 of the Appendix, at reference characters 156-2 and 156, respectively. As generally indicated at 160, the remaining parameter of the selected capacitor, viz., the insulation resistance, is measured. This parameter is obtained by measuring the leakage current of the selected capacitor at one or more predetermined applied electrical potentials. The necessary electrical potential may be obtained in any convenient manner. For example, in the preferred measurement instrument 22 identified above an internal voltage source is associated therewith. Block 160A is a branch to either connect the internal voltage source of picoampere instrument 22 or to connect a separate external voltage source 12. The following paragraph assumes that the internal voltage source of the instrument 22 is used. See, page 34 of the Appendix, at reference character 160A. To effect the measurement, as seen at 160B, the controller 26 commands the instrument 22 to apply a desired electrical potential (initially specified by the operator) to the selected capacitor. See, page 35 of the Appendix, at reference character 160B. At 160C the controller 26 asserts the appropriate relay arrangement 85 over the lines 87L, 88L from the relay control module 110. See page 36 of the Appendix, at reference character 160C. Relay 87 connects the measurement terminals of picoampere instrument 22 and relay 88 connects the internal source of voltage potential to the rails 42, 44. As seen at 160D, the controller 26, under program control, then selects a predetermined one of the capacitors. The desired one of the capacitors is selected by closing the corresponding one of the relays 66-1 through 66-N by the controller 26 sending a -command to the relay output control 110 which asserts the appropriate one of the coils 66S in the appropriate relay 66 to connect the fixture between the high and low rails 42 and 44, respectively. See, page 35 of the Appendix, at reference character 160D. The instrument 22 is then asserted, at 160E, by the controller 26 to measure (after a predetermined time delay, if desired) the leakage current through the selected capacitor at this applied voltage. See, page 35 of the Appendix, at reference character 160E. At 160F the reported value of leakage current is stored by the controller 26 in its memory. See, page 35 of the Appendix, at reference character 160F. If the specified insulation resistance test voltage of the capacitor exceeds the voltage limit of the instrument's internal voltage source, it is necessary to connect a separate external source of voltage to the selected capacitor. In the embodiment illustrated, this separate external source of voltage or potential is supplied from the source 12. As seen at 160C the controller 26 asserts the third relay arrangement 86 over the lines 87L, 98L from the relay control module 110. See page 36 of the Appendix, at reference character 160C. Relay 87 again connects the measurement terminals of picoampere instrument 22 to the rails 42, 44. The relay 98 connects the supply 12 to the high rail 42 and the common point 94 and thus to the selected capacitor. A similar sequence would be utilized if the picoampere measurement instrument 22 does not contain an internal source of potential. Once the separate external supply is connected, a command is sent from the controller 26 via the digital output module 122 to set the output voltage of the supply 12. Once the external voitage is applied, the instrument 22 measures (after a predetermined time delay, if desired) the leakage current through the selected capacitor at this applied voltage. At 160F the measured value of leakage current is read and stored by the controller 26 in its memory. See, page 35 of the Appendix, at reference character 160F. Once the given one of the capacitors is measured in the manner outlined above, a different capacitor is selected by opening the previously closed relay 66 and closing the relay 66 associated with next capacitor to be tested. The testing of each selected capacitor proceeds in a fashion corresponding to that discussed heretofore. If multiple test voltages have been specified by the operator the above sequence (160A through 160F) is repeated for each specified voltage. After the capacitors have been measured at each specified voltage, the capacitor discharge routine 154 is again performed. At 160G once all of the capacitors have been tested the instrument is disconnected from the selected capacitor by turning off the relay arrangement 86. See page 36 of the Appendix, at reference character 160G. The overall temperature of the capacitor holding assembly 16 is again measured by causing the digital input module 126 to read the output of the digital temperature measuring device 24. See, pages 21 and 47 of the Appendix, at reference character 156-3 and 156. As seen at the call 154-3, the routine 154 is again performed. The discharge relay 103 is again asserted in a manner identical to that described above. See pages 21 and 31 of the Appendix, at reference characters 154-3 and 154, respectively. The controller 26 then signals the operator that the tests have been completed. The operator opens the door D of the holding assembly 16 and removes the capacitors therefrom. At 164 the controller 26 reports the test results in the desired format. Examples of such formats include printed tables of values or plotted histograms of the desired parameters. See, for example, page 21 of the Appendix, at reference character 164. As seen at 166, the information may also be stored on magnetic media for archival purposes. See, for example, page 56 of the Appendix, at reference character 166. - " * ' Those skilled in the art, having the benefit of the teachings of the present invention, may effect numerous modifications thereto.
