Check wheter the test force is approximately correct or not.

1. Prepare the test force calibration jig.

2. Insert the joint for UJ into the bo ttom hole of the tensile joint, and and fix with the pin.
3. Set the test force polarity to Tensile.
4. Performe the electronically calibration (E-CAL).

5. Check that the displayed test force value increases by pushing the weight with your hand.
6. Set the weight in the calibration jig.
7. Confirm that the test force value is within the allowable error range below.
  Allowable Error Range:
    within 1% of indicated value for standard accuracy
    within 0.5% of indicated value for high accuracy
