Calibration of SPIDER BONDED TEST FIXTURE
Calibration Purpose
In order to meets the following requirements
* Must weigh more than 3.6 lbs
* Must weigh less than 4.6 lbs
The correctequipment is needed to calibrate the spider fixture. They must have the necessary range, accuracy, stability and have to be calibrated before of perform any comparison.
Required reference equipment;* Force Gage
* Motorized Test Stand
Calibration Procedure
I. Turn on the reference equipment force gage at least 30 minutes before of test.
II. Confirm that the measurement units isdisplayed in the reference equipment Force Gage (LBF)
III. Confirm that the test stand is operating and coming up or down according to the button instruction (there is nothing touching the movementpart).
IV. Push the button to “up” in the control panel of test stand to place the spider fixture in the base of the test stand. See image

V. Place the spider fixture on the base of the teststand being aligned with the force gage “test bar”.

VI. Push the button down selecting the “MIN SPEED” 0.50IN/MIN to avoid potentials risk.
VII. Once the spider fixture test bar is comingdown to the Set Up mark on it, press the “STOP” bottom on the control panel of test stand when it is aligned with the fixture Spring Housing. See image

VIII. Manually push down the Hook Shaft ofthe spider fixture to the bottom of the fixture without moving the force gage and release it carefully and register the value showed in the force gage.

IX. The result have to be 3.5LBF to 4.5LF,otherwise the fixture have to be adjusted by mean of Spring Preload Adjustment.
X. Adjustment Procedure follows the entire calibration procedure until step VIII, loosen the Locking Nut and turnthe Preload Adjustment until the force achieves the required specifications 3.5LBF to 4.5LBF.
Note: there is no problem if the set up mark is too high or disappear below the edges.
XI. Lock the...
