except if Auto Return or Cycling are turned on. If so, PC control will be turned off automatically. 
 
 

7  MAINTENANCE AND SERVICE 

 

 

The TSTM-DC should be operated in a dry and clean area. Under these circumstances only a few 
periodic maintenance operations are required: 
 

7.1 Check for loosened grips and attachments – daily 

Check to ensure that the grips attached to the torque sensor and torque plate are firmly secured. 
Looseness could result in a potentially hazardous situation. 
  

7.2 Check for loosened components – once per month 

1.  Remove the test sample from the test stand.

 

 

2.  Attempt to loosen subcomponents of the test stand (ex. fasteners, brackets, etc). All components 

should be firmly attached. If any looseness is detected, stop using the test stand and contact 
Mark-10 or a distributor for instructions.

 

 

 

 

8   TROUBLESHOOTING  

 

 

1.  The control panel displays several error messages, as follows: 

 

Error Message 

Description

CHECK GAUGE 

The torque sensor/indicator is either (1) powered off, (2) not in its 
operating mode (i.e. in a menu), or (3) not connected to the stand. 
This message appears only if overload protection is turned on and 
one of the above conditions is present. 

GAUGE COMM ERROR 

The test stand is attempting to rotate, but it cannot establish 
communication with the torque sensor/indicator. The communication 
settings in the indicator are not correct or the indicator is not in its 
normal operating mode. 

GAUGE OVERLOAD 

The programmed overload percentage of the

 

torque 

sensor/indicator’s full scale has been reached. Immediately reduce 
the torque or adjust the overload settings. 

 

To clear any of the above errors, press 

STOP

.  

 

2.  The test stand will rotate only in one direction, or not at all.
