NOTE At this time the Cognizant Supervisor shall make the judgement to determine if the cell(s) should be jumpered or to continue the test with the cell(s) installed. This judgement should be based on Total Test Time,,overall Bank Voltage, and the number of cells at or below 0.75 volts.

IF th; Cognizant Supervisor's judgment is to continue the test with the cell(s) installed, THEN restart the discharge at the calculated current and record the restart time below and on Attachment 3. Continue recording data on Data Sheet 1 and discharge the bank until the bank voltage approaches 105 VDC, N/A Steps 3 through 11 of this Attachment and continue with Step 12.

IF the Cognizant Supervisor's judgement is to jumper the cell(s),
