                       * * * * OHMS READINGS * * * * 


THIS IS A LISTING OF NORMAL AND ABNORMAL READINGS WHEN SHORT CHECKING
MBOX MODULES OF THE JUPITER.  ** NOTE THAT THESE NORMAL READINGS WERE
TAKEN ON A KNOWN GOOD MCC BOARD. **
 
 

            A.  NORMAL READINGS

                1. TERMINATED SIGNAL TO -2V ......... 56 OHMS
                 
                2. TERMINATED SIGNAL TO -4.5V ....... 87 OHMS

                3. TERMINATED SIGNAL TO GND ......... 100 OHMS

                4.      -2V TO GND .................. 55 OHMS

                5.      -2V TO -4.5V ................ 32 OHMS

                6. ACROSS -2V CAPACITOR ............. 55 OHMS

                7. ACROSS -4.5V CAPACITOR ........... 86 OHMS

                8. BETWEEN 2 DIFFERENT NETS ......... 110 OHMS
                           <BOTH NETS TERMINATED>


            B. ABNORMAL READING INDICATIONS

                1. 28 OHMS ....... DOUBLE TERMINATION

                2. 38 OHMS ....... ETCH SHORT BETWEEN 2 NETS, BOTH TERMINATED

                3. 16 OHMS ....... MISSWIRE ON DIP <GROUNDING A # OF SIGNALS>

                
B.3. THIS INDICATION IS ACTUALLY THE RESULT OF 4 SEPARATE NETS BEING TIED
        TO GROUND AND THEREFORE QUADRUPLE TERMINATED.

         EX.  DOUBLE TERMINATION = 56 OHMS / 2 = 28 OHMS
              QUAD TERMINATED = 56 OHMS / 4 = 16 OHMS
