II Working principle of printing wireless hook scale:

Hang the lifting ring of the electronic suspension scale on the hook of the crane. When an object is hung on the hook of the electronic suspension scale, the sensor inside the scale body is deformed by tension, and the current inside the sensor changes. Then, this changing current is converted by A/D and the wireless signal is sent out by the transmitter. According to the regulations of the National Radio Regulatory Commission, electronic suspension scales are generally sent out at 230MHz and 450MHz. After the receiver receives the signal, it is transmitted to the instrument, and then converted and calculated by the instrument, and finally displayed.

(1) Before using the electronic hanging scale, the corresponding battery should be installed in the scale body and handheld device. When installing or replacing the battery, the battery clamp locking screw should be tightened to check if the battery clamp is firmly fixed on the scale body. Then, the hanging scale door should be closed and locked to prevent accidents. When the instrument displays undervoltage, the battery pack should be replaced immediately and the replaced battery should be charged in a timely manner to prevent battery damage. When the battery pack is not used for a long time, it should be charged at regular intervals. The battery should be stored in a dry, ventilated, and suitable temperature environment, and avoid contact with corrosive substances. When loading and unloading the battery pack connection wire aviation socket, do not hold the wire clamp cap that clamps the wire with your hands, but should hold the base tightly. When connecting the power supply on the other side of the transmitter to the aviation plug, do not hold the wire clamp cap. Instead, hold the rotatable cap on the head for loading and unloading to prevent loose power connections and faults. Before connecting the transmitting device to the power supply, the antenna and its feeder must be reliably connected, otherwise the transmitting device will be damaged.

(2) Avoid violent pulling and collision of electronic suspension scales. Many electronic components inside the electronic suspension scale, such as integrated circuits, quartz crystals, sensors, displays, etc., may be damaged when the electronic suspension scale is subjected to violent collision, causing the electronic scale to malfunction, affecting accuracy and normal use. It is necessary to avoid collision between the scale body and other objects or falling from a high altitude. The instrument should be handled gently and not placed randomly to prevent unnecessary losses. When the instrument is fixed on the crane for use, vibration reduction measures should be taken to avoid affecting reliability.

(3) Do not dismantle the components on the electronic suspension scale at will. When the electronic suspension scale is in normal use, do not dismantle the components on the scale at will, and do not open the sealing port on the sensor or disassemble the integrated circuit and other components on the instrument. Necessary repairs must be carried out under the guidance of relevant technical personnel or with certain maintenance knowledge to prevent the fault from expanding.
