Test Equipment
•
The description of test equipment in Table 7.1 includes
the manufacturer’s type/model numbers that are available
as of the publication date. Since certain models of test
equipment may become discontinued or superseded by
the manufacturer an anytime, it is recommended that
a manufacturer’s current catalog be used when ordering
the equipment. The test equipment manufacturers listed
are for reference only and are not intended to show a
preference for any one manufacturer. Equivalent test
equipment may be used unless otherwise noted. Regardless
of the test equipment used, it must be properly maintained,
calibrated, and operated according to instructions given
by the manufacturer.

If solar panels and storage batteries are used, measure
the voltage across Charge Controller input terminals (+)
and (-). Confirm the proper polarity. The voltage reading
should be b12 and +17 Vdc. If the polarity is
incorrect or there is no voltage, check and correct the
wiring to the solar cell panels. If the voltage is low, check
to be sure the surfaces of the solar panels are not obscured
from sunlight. Next, remove battery input fuses F101 and
F103. Battery output fuses should now be in place. Measure
the voltage across terminals 1 (-) and 2 (+) and across
terminals 3(+) and 4 (-) of repeater terminal block TB-1.
Confirm the proper polarity. The voltage reading should
be +12.5 to +13.5 Vdc for storage batteries or +13.0 to
+15.0 Vdc for an ac power supply. If the polarity is
incorrect or there is no voltage, check and correct the
wiring of the batteries or ac power supply. Replace
battery fuses F101 and F103.
