* S1 or S2 shaft between gears
Note: When working with gear ratios always reference one number to
“one.” Examples: (4:1) or (1:4).
State “ to ” ratios as “(1-100)” to “(1)” or “(1) to (1-100)”
Do not guess or estimate the values of optional questions.
The Fluke 810 Vibration Tester can analyze:
Motors • Couplings • Spindles • Close-coupled machines • Blowers • Gearboxes • Fans • Belt and chain drives •
Pumps (piston, sliding vane, propeller, screw, rotary thread/gear/lobe) • Compressors (piston, screw, centrifugal)
