4. MEASURING AND CHECKING PROCEDURES

4-1) INSTRUMENTS

(1)VOLTMETER

AC voltmeter is 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 330 V : Dual voltage type

(2)AMMETER

AC ammeter is 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)

(3)FREQUENCY METER

Frequency range : To cover 45 to 65Hz

NOTE : Be careful of the frequency meter's input voltage range.
