8. MEASURING PROCEDURE
8-1 METERS
8- 1 - 1 VOLTMETERS
AC and DC voltmeters are necessary. The approximate AC
voltage ranges of the voltmeters to be used for various types
of generators are as follows:
0 to 150 V: Type with an output voltage of 110 or 120 V
0 to 300 V: Type with an output voltage of 220,230, or
240 V
0 to 150 V, 0 to 300 V: Dual voltage type
The DC voltmeter range is approximately from 0 to 30V.

8- l-2 AMMETERS
AC and DC ar:meters are necessary. An AC ammeter with a
range that can be changed according to the current rating of
a given generator is most desirable. (About 10 A, 20 A,
100 A)
The DC ammeter range is approximately from 0 to 15 A.

8-l -3 FREQUENCY METER
Frequency range: About 45 to 65 Hz
NOTE: Be careful of the f=quency meter's input voltage
range.
