Caution-conditions that may damage the instrument. 

 

 

Do  not  use  this  instrument  for  any 

application  other  than  the  calibration  work.  

Any  other  use  of  the  instrument  may  cause 

unknown  hazards  to  the  user.  Also 

Completely  unattended  operation  is  not 

recommended 

 

 

Do not use the instrument if the Cooling fan 

located  at  the  bottom  of  the  Instrument  is 

out of order 

 

 

Always  operate  this  instrument  at  room 

temperature at 23 ± 2˚C. Allow sufficient air 

circulation  for  the  instrument  by  leaving  at 

least 6 inches (15cm) of clearance around the 

instrument 

 

 

Do  not  turn  off  the  instrument  at 

temperatures higher than 100˚C. This would 

create  a  hazardous  situation.  Select  a  set-

point less than 100˚C (preferably close to the 

ambient  temperature)  and  allow  the 

Instrument to cool before it turning OFF. 

 

 

Component  life  time  can  be  shortened  by 

continuous high temperature operation. Use 

of  this  instrument  at  HIGH  TEMPERATURES 

for  extended  periods  of  time  requires 

caution. 

 

 

Not to be used in explosive zones.
