a As far as possible, bring pump discharge pressures; P1 and P2 as close as possible to the average pressure when
measuring. The error is large near the point where the graph curves, so avoid measuring at this point.
a When measuring with the pump mounted on the machine, if it is impossible to set the engine speed to the specified speed
with the fuel control dial, take the pump discharge amount and the engine speed at the point of measurement and use them
as a base for calculating the pump discharge amount at the specified speed.
