Input Selections 

The  input  selection  indicates  which  input  is  selected;  T1  thermocouple,  T2 
thermocouple  or  the  difference  between  the  two  thermocouples  (T1-T2). 
When the thermometer is turned on, it is set to the temperature input that was 
in use when the thermometer was last turned off. 
 
Selector Switch 
The circular selector switch is used to turn the unit off (

) or to select Reading 

Mode  (Input)  or  Simulation  Mode  (Output).  There  are  nine  selector  switch 
positions  under  output  which  provide  rough  adjustment  of  the  simulated 
output. 
 
Adjust 
Course  and  fine  adjustment  Dials  are  used  in  Simulation  Mode  to  allow  a 
particular  simulated  temperature  to  be  selected  once  the  output  has  been 
adjusted close to the desired temperature using the selector switch.

 

2.3 Read Mode Procedure 

 
1. Plug Thermocouple Sensor into input T1 and/or T2. 
2. Turn selector switch to Input. 
3. Select proper thermocouple type (J, K, T or E) using type button. 
4. Press T1 button to read thermocouple connected to input T1. 

Press T2 button to read thermocouple connected to input T2. 
Press T1-T2 if difference between T1 and T2 is to be read. 

5.  To  Hold  reading  press  HOLD  button.  To  resume  making  measurements 

press HOLD again. 
Note: Unit will display -OL if input is out of range or thermocouple is broken 

or not connected to proper input. 

 

To save battery life, CL3512A will turn off automatically if no is key is pressed 
for 90 minutes.
