4. When 35 seconds have elapsed, turn the shunt to the ¹/₁₀₀₀-post and watch the galvanometer throw; if small, move the shunt successively to the ¹/₁₀₀-post, to the ¹/₁₀-post, and to the unity post. This operation must be completed before 45 seconds have elapsed from the time the key was closed. With good cable the unity post will always be reached without danger of throwing the galvanometer reading off the scale. Remember that each successive post should give 10 times the throw of the preceding post. 5. At the end of one minute read the deflection, correct for the leakage of the leads and the earth currents, and record. (See example following.) 6. At the end of two minutes read the deflection, correct and record it. For good cable it should be less than the deflection observed at the end of one minute. 7. Turn the shunt to 0, and reverse the key, stopping at the discharge position. Turn the shunt on gradually until the unity post is reached and wait until the reading is 0, indicating that the conductor is discharged. If earth currents are present, 0 will not be reached or will be passed. In this case proceed as before described. A submarine mine cable conductor a mile long will discharge ordinarily in about three minutes. 8. Turn the shunt to 0, stop and start the stop watch; at the same time close the key all the way down (- to earth). 9. After 35 seconds, start turning the shunt, ceasing at 45 seconds. (See paragraph 4, above.) 10. At the end of one minute read the deflection, correct and record it. For good cable it should be substantially the same as the deflection observed at the end of one minute with + of the battery to earth. 11. Turn the shunt to 0, and reverse the key, stopping at the discharge position. 12. Disconnect No. 2 conductor from ground. Disconnect No. 1 from the lead and connect up No. 2. Connect No. 1 to ground. It is not necessary to wait for No. 1 to be discharged completely before disconnecting it. 13. Proceed with No. 2 as with No. 1 and repeat with each conductor. 14. On the completion of the test all conductor ends should be carefully taped.
