Setting the Velocity Detector in Gravity Mode
The velocity of the crosshead when operating in the gravity mode can be determined
analytically with the following equation:
v = 2 gh
Where: v = theoretical velocity ft/sec (m/sec).
g = acceleration of gravity 32.17 ft/sec
2
(9.8 m/sec
2
).
h = drop height in ft (m)
