(see 6.4.1)
Previous version
New version
If the system is in order, the
ohmmeter should indicate, in
measuring range "Ω x 1", a value of
about 2.5 Ω on previous heating
elements or between 7.2 Ω and
9.4 Ω on new heating elements
(see also 6.4.). If no reading is
obtained, there is a break in the
circuit. If the ohmmeter shows a
value of less than 2.5 Ω or 7.2 Ω,
there is a short circuit in one of the
components.
In either case it is necessary to
check each component separately.
The generator wire remains
disconneted from the heating
element during this check.
