Answer
1. Turn off the instrument.
NOTE: Before replacing a load cell, turn off the power or disconnect the CAL connector from the smart controller according to the specified procedure. Connecting/disconnecting the CAL connector during E-CAL or other data communication may corrupt calibration data.

2. Remove the test jig from the load cell.
3. Loosen the two fixing screws (1) of the CAL connector on the right side of the instrument and remove them.
4. Remove the load cell from the crosshead.
• For 10kN or smaller load cells, loosen the fixing bolt of the load cell with a rotation bar and while holding the load cell with one hand, turn the fixing bolt with another hand to remove it.
• For 10kN or larger load cells, use a hex wrench to loosen the bolt and remove it from the crosshead.
• For 10kN or smaller load cells, loosen the fixing bolt of the load cell with a rotation bar and while holding the load cell with one hand, turn the fixing bolt with another hand to remove it.
• For 10kN or larger load cells, use a hex wrench to loosen the bolt and remove it from the crosshead.
5. Attach the replacement load cell to the crosshead, so that the text on the nameplate of the load cell is shown with the right side up.
NOTE:
NOTE:
• Tighten the supplied bolt until the load cell is secured to the crosshead without looseness. Otherwise test force may not be measured correctly.
• Do not remove or loosen the locating plate for load cell on the top surface of the crosshead. Otherwise, a correct position of the load cell cannot be set.
• Do not remove or loosen the locating plate for load cell on the top surface of the crosshead. Otherwise, a correct position of the load cell cannot be set.
6. Connect the load cell side end (1) of the load cell cable to the connector (2) of the load cell securely.
« 20kN or larger load cells »
HINT: This connection is not necessary for 10 kN or smaller load cells since they have an integrated load cell cable.
« 10kN or smaller load cells »
NOTE:
• A load cell and CAL connector are calibrated as a set before shipment. Be sure to use a set of a CAL connector and load cell that are included in the same package. Connecting any CAL connector other than the supplied one will cause an abnormal test force preventing the load cell from properly detecting overload.
• Tests cannot be performed after the load cell is replaced/attached unless E-CAL is executed.

• Do not perform operation that may apply load to the crosshead while a load cell is not attached or the attached load cell cannot receive transmitted load. Doing so may damage the frame or jig.

7. Secure the load cell cable to the cable guide (1) on the left of the rear side of the crosshead and on the pole side.
NOTE: When securing the load cell cable to the cable guide, keep enough length of the load cell cable to allow the crosshead to move through the movement range.

8. Connect the load cell cable to the CAL connector.
9. Connect the CAL connector to the sensor amplifier (for load cell) (1) and fix it with the connector fixing screws.
HINT: The sensor amplifier connector port may be located on the rear side of the control box. Contact a Shimadzu sales or service representative.

1. Attach a load cell to the tester.
« For table-top type »
1) Put the cell bolt (1) (a special fixing bolt) through a hole at the center of the crosshead from above.
2) Screw the male thread of the cell bolt (1) protruding from the bottom surface of the crosshead into a tapped hole on the top surface of a load cell (2).
3) After the top surface of the load cell (2) is brought into intimate contact with the bottom surface of the crosshead, tighten the cell bolt (1) with a rotation bar supplied with the tester to securely fix the load cell (2).

3) After the top surface of the load cell (2) is brought into intimate contact with the bottom surface of the crosshead, tighten the cell bolt (1) with a rotation bar supplied with the tester to securely fix the load cell (2).
« For floor type »
1) Place a load cell (1) aligned with the locating plate at the center of the top surface of crosshead.
2) Fix the load cell (1) to the crosshead with the supplied eight bolts.
3) Always tighten the bolts in a crisscross pattern as shown in the below figure.
NOTE: For a 250kN/300kN/600kN load cell, tighten with a tightening torque of 280N·m.
