Robin RGD500 - 9 Checking Functional Members; Voltmeter; Ac Receptacles; No-Fuse Breaker

9.CHECKING FUNCTIONAL MEMBERS
9-1 VOLTMETER
Check the the voltmeter if it is turned on by apply-
ing specific voltage.
Voltmeter cannot be checked with circuit tester
because
its resistance is too large.
9-2 AC RECEPTACLES
Using a "Dr. Robinnor a circuit tester, check conti-
nuity between the
two terminals at the rear of the
AC receptacles while the receptacle is mounted
on the control panel.
Fig. 9-1
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.
