Operation instructions:
1. Supply power to the electrical control box and turn on the power switch.
2. Fix the adjusting screw on the upper cover and fix the sensor on the adjusting screw.
3. Place the jack on the base, place the roller support on the jack telescopic rod, and then place the test roller vertically on the roller support.
4. Adjust the length of the sleeve (or replace the sensor mounting bolt) by adjusting the length of the sleeve and the tension sensor according to the length of the roller.
5. The operating jack is gradually raised until the upper roller shaft is in contact with the sensor adjusting sleeve. During the ascenting process, the jack position should be properly adjusted to ensure that the roller shaft center line and the adjusting sleeve are in contact with the sensor adjusting sleeve. The center line of the barrel is as close as possible.
6. The operating jack is gradually and slowly pressurized until the sensor meter reading reaches the load value specified by the roller (meter reading, unit is KN).
7. Operate the jack to unload.
8. Check whether the roller shaft (including the bearing seat, sealing device) is disengaged from the roller tube. If it is not disengaged, it is qualified, otherwise it is unqualified.
