The hook scale is widely used, but do you know how to use the electronic hook scale correctly? Here are some guidelines for the use of hook scales:

1. The hook scale must be in a vertical floating state before being turned on, and it is in an idle state.
2. Press ON/OFF for 2 seconds without turning on. After displaying UERT-8.0, the full scale value will be displayed. Then the current voltage of the battery will be displayed. When the self-test indicates that the voltage is lower than 5.2V, it needs to be charged in time.
3. When you need to replace the battery, please observe the principle of “opening the cover after breaking the power first”.
4. When the object is weighed, it should be timely cleared when there is a hanging connection device outside the weighing object (such as: sling, wire rope, U-hook, etc. and ensure that the hanging connection equipment is in a suspended state to avoid the weight of the weighing object. error)
5. It is forbidden to use the remote control when the power is not stable.
6. Use the body to clear the red button when clearing
7. When weighing, keep the hanging object steady. When reading the scale, it needs to be stable after 3-7 seconds.
8. When the use is finished, it should be said to be in the no-load state or put back on the weighing frame to clean the scale body.
9. When the scale body needs to be put back on the scale, it must be placed in the specified direction and the power is turned off.
10. It is forbidden to hang heavy objects for a long time.

11. When using the hook scale, it must be lightly hoisted, no collision, no emergency, no emergency
12. When lifting heavy objects, ensure that it is safe and reliable: the crane hooks are moved to the top of the load. When approaching the load, the speed should be reduced so that the load can be gently hanged. The load should be completely in the hook of the crane. At the center, after the fuse is closed, slowly raise the crane scale and ensure that the load is hoisted smoothly
13. Strictly follow the requirements of the “seven-step crane”: the signal is unclear “not hanging”, the overload is “not hanging”, and the fastening is not secure “not hanging”.
Some people on the heavy lifting object "do not hang", the safety device does not work "do not hang", the diagonal pull "do not hang", can not see the "not hanging"
14. It is strictly forbidden to hang a load larger than the rated weight of the hanging scale.
15. Pay attention to the protection of the sensor for the scale body, and prevent the scale body from being damaged by excessive impact.
16. The sensor is a metal mechanism to prevent contact with water, oil and corrosive liquids.
17. The sensor and signal line are vulnerable parts, and regular inspection is required.
18. The instrument head is a precision instrument, first of all to ensure that the voltage and current meet the parameter requirements.
19. It is strictly forbidden to plug and unplug all signal plugs during operation, otherwise it will easily burn out the integrated circuit.
