Checking the Rotor Speed
Rotor speeds ( + 5%) may be checked with a stroboscope or photoelectric tachometer.
1. Remove the rotor and locate the reflective patch located on the top of the drive cone.
Close the instrument cover.
2. Set the instrument to the desired speed.
3. Point the tachometer through the transparent cover at the reflective patch.
4. Press the Start button. Allow the instrument sufficient time to reach speed before making
a measurement.
If the instrument fails to maintain set speed within specified tolerance contact customer service
or your distributor.
CAUTION - Do not defeat any safety interlocks while checking the rotor speed. Bypassing
interlocks could result in personal injury.
