Service 

–  Due  to  the  sophisticated 

nature  of  the  sensors  and  associated 
instrumentation 

provided 

by 

PCB 

Piezotronics,  user  servicing  or  repair  is 
not  recommended  and,  if  attempted, 
may  void  the  factory  warranty.  Routine 
maintenance,  such  as  the  cleaning  of 
electrical  connectors,  housings,  and 
mounting  surfaces  with  solutions  and 
techniques  that  will  not  harm  the 
physical  material  of  construction,  is 
acceptable. Caution should be observed 
to  ensure  that  liquids  are  not  permitted 
to  migrate  into  devices  that  are  not 
hermetically 

sealed. 

Such 

devices 

should  only  be  wiped  with  a  dampened 
cloth  and  never  submerged  or  have 
liquids poured upon them.   
 

Repair 

–  In  the  event  that  equipment 

becomes 

damaged 

or 

ceases 

to 

operate,  arrangements  should  be  made 
to  return  the  equipment  to  PCB 
Piezotronics for repair. User servicing or 
repair  is  not  recommended  and,  if 
attempted, 

may 

void 

the 

factory 

warranty.     
 

Calibration 

–  Routine  calibration  of 

sensors  and  associated  instrumentation 
is  recommended  as  this  helps  build 
confidence  in  measurement  accuracy 
and 

acquired 

data. 

Equipment 

calibration 

cycles 

are 

typically 

established  by  the  users  own  quality 
regimen.  When  in  doubt  about  a 
calibration cycle, a good 

“rule of thumb” 

is to recalibrate on an annual basis. It is 

also  good  practice  to  recalibrate  after 
exposure  to  any  severe  temperature 
extreme, 

shock, 

load, 

or 

other 

environmental  influence,  or  prior  to  any 
critical test.  
 
PCB  Piezotronics  maintains  an  ISO- 
9001  certified  metrology  laboratory  and 
offers  calibration  services,  which  are 
accredited  by  A2LA  to  ISO/IEC  17025, 
with  full  traceability  to  SI  through 
N.I.S.T.  In  addition  to  the  normally 
supplied  calibration,  special  testing  is 
also  available,  such  as:  sensitivity  at 
elevated  or  cryogenic  temperatures, 
phase  response,  extended  high  or  low 
frequency  response,  extended  range, 
leak 

testing, 

hydrostatic 

pressure 

testing,  and  others.  For  information  on 
standard 

recalibration 

services 

or 

special  testing,  contact  your  local  PCB 
Piezotronics 

distributor, 

sales 

representative,  or  factory  customer 
service representative.   
 

Returning  Equipment 

– 

Following 

these  procedures  will  ensure  that  your 
returned  materials  are  handled  in  the 
most 

expedient 

manner

Before 

returning 

any 

equipment 

to
