5. Dual-Operated “Major” Type
FIGURE 8
This set consists of a constant-voltage “Megger” type instrument
modified for use with a separate, special rectifier power supply.
It may be operated either by its own hand cranked generator or
by means of the power supply.
When using the hand-cranked generator, follow directions for
“Constant-Voltage Type” (page 7). The power supply must be
disconnected from the instrument.
When using the special rectifier power supply, make sure that it
corresponds by Cat. No. and voltage rating to the instrument with
which it is to be used. Connect power supply to instrument by
means of plug connection attached to power supply unit. Follow
directions for “Rectifier-Operated Major Type” (page 8).
If the special rectifier power supply is used for purposes other
than operating its companion “Megger” Insulation Tester, its
rated current output must not be exceeded. CAUTION: There
is no series resistance in the power supply to limit its current output.
