   DIMENSIONS

   Measuring force is generated by the action of trapping a workpiece between the spindle face and the anvil.
   The constant-force unit applies the specified measuring force.
   When the preset measuring force is reached, the value on the LCD is automatically held and the hold symbol appears.
   (To cancel the hold, reverse the thimble more than 1/10 revolution and press the hold button.)
