Operation 

 

DTR-65 control 
buttons 

 

 

There are three manual control buttons on the DTR-65.  

 

 

[+] 

=  increment 

[-] 

=  decrement 

[

=  zero tension, or 

enter or save function 

 

 

 

Power on 

 

 

 

The DTR-65 will display the software version number when 
power is first applied for five seconds and then the DTR-65 will 
start displaying the tension. During the software version display, 
diagnostics are performed on the load cells and any errors are 
displayed. 

The load cell diagnostic errors are shown in Table 3. 

To exit from the load cell diagnostic error, press [

] and the 

tension will be displayed. 

If no errors are detected, the tension will be displayed.
