Thank you for purchasing your product from Castle Group Ltd. 
 
The  Castle  Pocket  Vibration  Meter range  has been designed  to  deliver cost 
effective vibration measurement solutions. 
 
Your  instrument  can  cater  for  various  degrees  of  experience  with  it  being 
simple to to operate and interprate the measurement results. 

 

 
 
 
 

Using the Manual 

 
In the course of this manual  a  named  button written in 

BOLD 

means press 

that button E.g. 

OK

 means press the OK button 

 

 

 
 
 

Notes Before Use 

 
Due to the compact screen it has not been possible to fit the full notation for 
velocity  units  and  the  value,  so  the  units  displayed  as  ms

-1

  are  actually 

millimeters per second or mms

-1

 
There is a slight delay between switching the unit off and it turning off, this is 
while your data is backed up.  If the power switch is pressed during this delay 
your settings may be lost. 
 
Holding your finger on a key will mean the key is pressed successively as far 
as the instrument is concerned.  To avoid confusion when using the keypad, 
press the keys firmly and release them quickly. 
 
If  using  the  instrument  with  a  magnet  make  sure  you  have  removed  the 
keeper (metal disc covering the magnet) from the magnet before use.
