7-1-5 MEGGER TESTER
Used for measuring generator insulation resis-
tance.
Select one with testing voltage range of 500 V.
7-1-6 TACHOMETER
There are various types of tachometers, such as
contactless type, contact type, and strobe type. The
contact type can be used only when the generator
and engine have been disassembled. The contact-
less type is recommended.
7-2 AC OUTPUT MEASURING
Use a circuit like the one shown in the figure above for measuring AC output. A hot plate or lamp with a
power factor of 1.0 may be used as a load. Adjust the load and rpm, and check that the voltage range is
as specified in the table below at the rated amperage and rated rpm.
Rated voltage 120 V 240 V
Voltage range 117 ~ 130 V 235 ~ 260
