-
Hang the upper hook of the turnbuckle onto the spring scale. Using a wire rope, hoist the upper end of the spring scale.
-
Attach the lower hook of the turnbuckle to a position 10 mm from the probe tip. Fasten the hook with adhesive tape to avoid slipping.
-
Reset the spring scale by pressing the zero key, ensuring that the probe is in an unconstrained condition.
-
Turn the turnbuckle to raise the tension and set the load. Since the turnbuckle stroke is short, adjust bends in the hoisting wire.
-
Since only one loading orientation is used, set the sensor properly in the loading orientation by rotating the sensor flange by 90 degrees at a time. Adjust the turnbuckle to achieve the specified load.
