Otherwise the monitoring will be incorrect.
After the vibration sensor is mounted make sure that the cable connected to the
display unit is uncoiled!
Install the vibration sensors only on the grounded equipment!
There is settling time for accelerometer that should be taken in account to perform
accurate measurements. After placing accelerometer on the object wait 2-3

5.3. Laser tachometer installation
BALTECH VP-3470 uses a laser tachometer to detect the rotor rotation frequency.
The laser tachometer should be installed using a magnetic rack in compliance with
the safety measures. The laser beam line must be directed toward the rotor axis of
rotation. The permissible deviation of the laser beam from the normal to the rotor
surface is +/- 20 degrees.
