9. CHECKING FUNCTIONAL MEMBERS

9-1 VOLTMETER

Check the voltmeter if it is turned on by applying specific voltage. Voltmeter cannot be checked with circuit tester because its resistance is too large.

1Check that no disconnection nor short-circuit occurs with a tester, and the internal resistance is around 00k ohms normally.

2Turn on the commercial power supply input and check the indication.

9-2 AC RECEPTACLES

Fig. 9-1

Using a “Dr. Robin” or a circuit tester, check continuity between the two terminals at the rear of the AC receptacles while the receptacle is mounted on the control panel. When continuity is found between the output terminals of the receptacle with a wire connected across these terminals, the AC receptacle is normal. When the wire is removed and no continuity is found between these terminals, the receptacles are also normal.

9-3 No-FUSE BREAKER

Check continuity between each of two terminals at the rear of the no-fuse breaker while it is mounted on the control panel. Normally, there is continuity between each of the two when the no- fuse breaker is on while there is no continuity when the no-fuse breaker is off.
