How to Measure RPM with the Tachometer
To make a Tachometer measurement:
1. Attach the Tachometer to the 6-pin DIN connector on
the Tester. See Figure 6.
2. Stop the rotating machine.
3. Attach a piece of reflective tape onto the shaft or
other rotating part of the machine.
4. Restart the machine and wait until it reaches its
normal operating conditions.
5. Aim the laser beam towards the attached reflective
tape.
6. Hold the Tachometer firmly and steady.
7. When the RPM entry screen appears on the display,
the power button on the Tachometer lights to indicate
that the Tester is ready for RPM measurement.
8. Push and hold the trigger button of the Tachometer
to start measuring.
9. Hold the trigger button until the RPM value settles
and displays on the Tester.
10. Release the power button to stop measurement.
11. Wait for the short beep that verifies the RPM value
has been acquired.
The Tester automatically turns off the Tachometer.
