8-l-l VOLTMETERS
XC and DC vo!tmeters are necessary. The approximate XC
voltage ranges of the voltmetsrs to be used for various types
of g2nerators are as follows:

8-l -2 AMMETERS
AC and DC ammetsrs are necessan-. Xn AC ammeter lvith a
range that can be changed according to ths current rating of
a given generator is most desirable. (About 10-a. 20.4.
