The use and maintenance of weighing instruments and common problems
1. Before application 1. The housing of the weighing instrument must have an excellent grounding device. 2. Turn off the switch power supply of the weighing instrument before plugging in the power plug of the sensor. 3. Before plugging in the serial communication port, turn off the power of the weighing instrument, copier or computer. 2. Common problems in application maintenance 1. This weighing instrument should prevent corrosive vapor liquids, conductive smoke and dust, and areas with severe vibrations, and pay attention to waterproofing. 2. The display screen is not suitable for application under the sun. 3. It is forbidden to use strong organic solvents (such as benzene, fluorobenzene oil) to clean the equipment shell. 4. If the weighing instrument has common faults during the whole application process, the switching power supply should be cut off immediately. 5. The gap between the floor scale and the support frame is small, and the dirt in the gap should be removed on time to prevent the weighing result from being compromised. 6. It is strictly forbidden to accumulate dirt around and on the floor scale. 7. Pay attention to the induction line around it when inspecting the ground scale safely. Pay attention to its footsteps. 8. Those who do not know the staff are strictly prohibited from touching all the function keys on the display. You can press the reset button every time you use it. 9. Sliding doors and oblique pressure are prohibited in the metrological verification slot. Pay attention to whether the nearby pipes (mainly the conductive soft connection of the left and right metal materials) are smooth and free of ground stress. 10. If the weighing instrument has common faults during the whole application process, the switching power supply should be disconnected immediately and sent to the company for repair. Non-professional workers do not need to repair themselves to prevent higher damage. 11. The weighing instrument of the metrological verification tank should be calibrated on time (to be determined for 3 months, if there is any problem in the metrological verification, calibration can be carried out anytime and anywhere) to ensure its accuracy and accuracy. 3. Practical operation and calibration 1. Start zero setting After the power-on self-check is completed, if the net weight is within the range of start zero setting, the displayed information net weight will be automatically reset to zero; otherwise, the displayed information net weight will not be easy to return to zero. 2. The function key is set to zero. In the case of weighing, press the →0← key. If the displayed information net weight is within the range of pressing the →0← key to zero, the displayed information net weight will be automatically reset to zero; otherwise the displayed information net weight will not be easily reset to zero . 1. The actual operation of tare weight 1. The actual operation of peeling. In the weighing condition, press the →T← key to take the current net weight as the tare, the display information net weight is 0, the [GROSS] indicator light is off, and [NET] displays Light. 2. The actual operation of clearing the skin In the weighing condition, press the C key to eliminate the tare weight and display the information net weight, the [GROSS] indicator light is on, and the [NET] indicator light is off. Message reminder 1. Message reminder 1. Display information OFL: Overweight alarm system. If it is an unadjusted scale, the data signal will fade after calibration. 2. The display information LCErr: indicates that the sensor is incorrect or the sensor is not connected. 3. The display information Err01: indicates that the entered number is incorrect. 4. Display information Err02: Net weight calibration cannot be carried out if there is no load on the weighing platform. Calibration method 1. In addition, press the first zero reset key and the fourth confirm key, the display will display a row of 0 information, press the fourth confirm key, cal1 will appear, and then press the second key to adjust cal1 to cal2. Press the fourth confirmation key to display the code, and then press OK. In addition, the display shows 0, add standard weight to display the information net weight. Press the OK key and a row of 0 appears. Enter the net weight of the added standard weight. Press the OK key to calibrate and return to the scale. Heavy web pages.
