head) of 1.6 inches of water (measured 12 inches from the
entrance of blast cap) including means to supply the cooling air
at a temperature of 77'F:t27oF (250C150C). Air pressure
can be controlled by placing an adjustable clamp over a fabric
hose connection.
Manometer
Manometer calibrated in inches of water should be used for in-
dicating air pressure.
Thermocouple
Thermocouples and associated indicators to measure frame
temperatures.
Instruments
Direct-current ammeter with a 0-5 ampere range for measure AC
generator field current and PM generator output.
Alternating-current ammeters with a 0-200 ampere range for
measuring line output currents.
Alternating-current voltmeter having a range of 0-300 volts and a
selector switch for measuring the line-to-line output voltage.
