(d) Slowly decrease the voltage at terminals 1 and 2. The relay must reset when the voltage is 8 ± vo1t ac. (7) To test the current transformer, proceed as follows: (a) Connect an ohmmeter across terminals 1 and 2, and across 3 and 4. In each case, the resistance must be 0.34 ohms ± 10 percent. (b) Apply 15 Vac to terminals 1 and 2 with secondary open circuit. The existing current must be less than 0.24 ampere. (c) Apply 15 Vac to terminals 1 and 2 with secondary-Open circuit. The voltage across term- inals 3 and 4 must be 15 volts ac ± 1 percent. (7a) Test the total resistance of rheostat (R28), (Mode II). Total resistance should be 15,000 ohms ± 10%. Test resistance between wiper arm and either end of rheostat. Resistance should vary between 0 and 15,000 ohms. (7b) Test the total resistance of rheostat (R29). Total resistance should be 12 ohms. Test resistance between wiper arm and either end of rheostat. Resistance should vary between 0 and 12 ohms. (7c) To test resistor assembly (A6) (Mode II) refer to paragraph (4a) and proceed as instructed. (7d) Check resistance of resistor (R31). Re- sistance should be 10 ohms. Change 1 8-19
