1.0 Introduction 

The  OMEGA

®

  CL3512A  calibrator/thermometer  is  two  meters  in  one.  The 

CL3512A  simulates  type  J/K/T/E  thermocouple  signals.  Each  signal  is 
adjustable by using the coarse and fine dials. The CL3512A can also be used 
as  a  dual  type  J/K/T/E  thermocouple  input  thermometer.  Features  include  a 
large 3½ digit display with backlighting and display selections of HOLD, °C/°F, 
and0.1/1°. 
The source mode of the CL3512A simulates the thermocouple output to check 
the  operation  of  a  thermocouple  meter  and  make  rough  calibration 
adjustments.  A  more  accurate  calibrator  would  be  required  for  calibration  of 
thermocouple meters to specify tolerances. 
 

1.1 Safety Information 

It is recommended that you read the safety and operation instructions before 
using the thermometer. 

WARNING 

To avoid electrical shock, do not use this instrument when working 

voltages at the measurement surface over 24V AC or DC. 

 

WARNING 

To avoid damage or burns, do not make temperature measurement 

in microwave ovens. 

 

CAUTION 

Repeated sharp flexing can break the thermocouple leads. To prolong 

lead life, avoid sharp bends in the leads, especially near the connector. 

 
 
 

 

1.2 Unpacking 

 
Remove  the  packing  list  and  verify  that  all  equipment  has  been  received.  If 
there  are  any  questions  about  the  shipment,  please  call  the  OMEGA 
Customer Service Department. 
 
Upon receipt of shipment, inspect the container and equipment for any signs 
of damage. Immediately report any damage to the shipping agent. 
 

 

NOTE 

   

The  carrier  will  not  honor  any  claims  unless  all  shipping
material is saved for their examination. After examining and
removing contents, save the packing material and carton in 
the event reshipment is necessary.
