Sensor Care and Handling
Caution
• To prevent damage to the piezoelectric
element inside the Sensor, do not drop.
A faulty Sensor significantly affects the
diagnostic quality.
• Do not pull or force the cable while
attaching or removing the Sensor.
• Allow the Sensor 10 seconds to warm-up
before data collection.
• Make sure that all cables are free from
any rotating parts of the machine.
• Always disconnect the Sensor cable
from the Tester when not in use.
• Always place the Sensor in the softcase
pouch when not in use.
Tachometer Setup
During the Machine Setup procedure, you have to enter
the speed/RPM (revolutions/minute) of the rotating
machine under test. If the RPM is unknown, you can use
the non-contact type laser Tachometer to measure the
RPM.
Note
Fluke recommends the use of a Tachometer for
variable-frequency drives (VFD) to determine the
running speed under varying load conditions.
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 3-4.
Warning
To avoid injury when attaching reflective
tape to the machine, stop the rotating
machine. Attach a piece of reflective tape
onto the shaft or other rotating part of the
machine. Restart the machine and wait until
it reaches its normal operating conditions.
2. Aim the laser beam towards the attached reflective
tape.
3. Hold the Tachometer firmly and steady.
