4  Care and Handling Guidelines 

1.

 

DO NOT subject the PRT to any physical shocks and vibrations.  

a.

 

When not using the PRT, keep it in a place that’s not prone 
to drop, slam, bang, vibration or other strong physical 
contacts. Use a protective box or a carrying case whenever 
possible. 

b.

 

When shipping the PRT, use protective box and other 
protective packaging materials to minimize mechanical 
shocks as much as possible. 

c.

 

When using dry blocks, make sure the well diameter is 
appropriate to allow the PRT move up and down smoothly. 
 

2.

 

DO NOT subject the PRT to any contaminations. 

a.

 

Keep the PRT as clean as possible. Avoid contaminations 
as much as possible. 
 

3.

 

DO NOT over heat.  

a.

 

Do not use PRT above the manufacture specified 
temperature range. 

b.

 

Do not expose the PRT handle and lead wires to extreme 
temperatures.
