What happens when the weighing instrument shows a negative number, and what to do after the negative number is displayed
Why does the weighing instrument have a negative value? How to deal with the negative value? There are two situations that cause the weighing instrument to have a negative value: 1. There is a problem with the electronic device weighing instrument. We know that the weighing instrument is the key to the electronic device weighing instrument, and the structure of the weighing instrument is the work pressure ductility structure. If the polyurethane elastomer of the weighing instrument does not return, it is very likely to have a negative value. 2. Is the internal limit switch of the weighing instrument and its internal power supply circuit damaged? How to define 1: Look at the standard value of bai. If the standard value is within -50KG, then it is because du is the key to the weighing instrument. It is a polyurethane elastomer. If the polyurethane elastomer is not dao calibrated, then a message will be displayed. Smaller negative values u200bu200bsuch as -10-20KG are all normal. Press and hold the zero key on the dashboard. 2: There is also a situation where a negative value appears, such as a hanging object on an electronic platform scale, and then some people Press the zero-setting button, then when the hanging object leaves the electronic platform scale, it will cause a negative value that is the same as the net weight of the hanging object! Press the weighing button or the zero-setting button to remove it 3: The weighing instrument is broken...Such a situation is very rare. Let's introduce the handling method for everyone: 1. First check if the working voltage is not enough. 2. Set it back to zero. If you do it again before weighing the object After adding the utensils, in order to better remove the net weight of the utensils, the zero return button is applied. If you remove the utensils, the same negative value will appear. 3. Use a weight to calibrate it and set the value again. 4. If the weighing instrument has been used for a long time, it is usually caused by the embrittlement of the weighing instrument. Check if the touch between the weighing instrument and the ADF is good. 5. If the PCB circuit board has returned to moisture, first check if the wiring terminal is carbonated. If the beverage penetrates, if there is the above-mentioned situation, use a hair dryer to dry it. 6. There are wastes around the weighing instrument. Do not allow mice, bed bugs, and other small microorganisms to invade the machine to prevent damage.
