Figure 1: Pocket-tach
1 Description
The Pocket-tach 100 will be used to measure the motor shaft speed while it is rotating. If you push the button on the Pocket-tach you should notice a small square of light shining from the top of the unit. When you need to measure the shaft speed, point the square of light from the Pocket-tach at the reflective tape on the coupling between the 2 machines. Please be careful when taking the measurements.
