What should I do if the weight display of the 30GJ bench scale is 0 after it is turned on?

Hello, show zero words.

You can call this a reboot.

It's all about unplugging the wires and reconnecting them.

Just open it again, and there will be display data.

I don't know what this error code represents.

In general, the following situations occur.

1.The weight placed on the scale is too heavy and exceeds the capacity of the scale.

2.In the initial set-up and debugging, some parameters are set incorrectly, or the debugging steps are operated incorrectly (if the scale was good before, the error code is suddenly displayed, this kind of situation is excluded).

3.If there is a problem with the poor contact of the line in the scale, it can be solved by rewiring.

4.The sensor is damaged.

5.The circuit board is flooded and burned out.

If the weight display is zero after the scale is turned on, it means that his system has not stabilized, and after a while, after its system is stabilized, its display will return to normal.

The weight of the 30gj bench scale is displayed as 0 after it is turned on. The boot display is displayed as 0, indicating that the current weight has been initialized and zeroed.

In this case, it is actually that the instrument can not recognize the correct and stable signal, or the scalar rate is lost, you can recalibrate the scale to try, if not, it should be a line or sensor problem

What should I do when the weight of the 30g platform scale is turned on and the weight is displayed at zero? Specifically, you should go to a professional mobile phone repair shop, or a professional correction place to test, or check it to the newly bought store to test it.

It may be broken by you, you can find the relevant after-sales personnel to help you repair it.

What should I do if the weight display of the 30 cv platform scale is zero after it is turned on, you can restart it, turn it off, and look again, it is also out of power.

This boot on this above these mechanisms.

The weight display of the 30g thief bench scale is zero after turning it on, and you can set it to zero.

In this case, it should be that the display resistor in the PC version is damaged, and in this case, the resistor must be replaced.

It's all like this, the default of the electronic scale is 0 grams, you have to wait for him to turn on, and then read the 9--0 digital display before you can put things.

Because when the machine is turned on, the electronic scale will do the tare weight operation, removing the weight such as the weighing pan, so it shows 0

After the electronic scale is turned on, there will be a process of skipping the meter and then automatically zeroing, so don't put anything on it during the period.

Set to remove the weight of the item.

Power on 1Please confirm whether the battery is charged, or it is recommended to remove the battery and reinstall it to try to turn it on. Or remove the battery and connect it to the charger after 5 minutes, and try to turn it on after 30 minutes, if it still doesn't work, please plug it in and try to see if it can be turned on.

2, or if possible, it is recommended to replace a battery, try it. 3. Still doesn't work, please (connect the charger) press and hold the power button and volume button to try whether you can enter recovery mode, enter the back three clear data, and try whether to turn on the computer. 3.

If it still doesn't work, go to a nearby repair point to have it tested. If the phone is really inexplicably hot, the best way is to take it to the store to repair it.

There is an electronic scale that does not display the weight when it is turned on.

Step (1): Check the battery voltage of the electronic scale first, which should be higher than 6V. If it is lower, please charge, if it is lower, and the battery is out of power soon after charging, please replace the battery.

Use the triple meter to turn to the DCV gear 20V, the red rod of the meter is placed at the position of the battery + end, and the black rod is placed at the position of the battery-end, and the battery voltage is displayed. Generally, the quality of the battery is judged by the speed of discharge after the charge is saturated, that is, when the charging circuit is normal, the battery cannot be charged (the charge cannot be entered). Or the battery needs to be replaced when it runs out of power after a short time after it is fully charged.

Generally speaking, the electronic scale can be used for more than 100 hours after being charged and saturated, taking the model without backlight as an example).

Step (2): Whether the fuse is open or not, if it is open, replace it.

Step (3): Whether the switch is bad.

First consider whether the sensor is broken, check whether the weighing platform and the scale frame have a top, then check whether the sensor signal line is open or short-circuited, and check whether the plug or socket of the signal line is not in good contact, and finally check whether the sensor parameters are normal, so as to avoid fearless consumption.

The following phenomena occur in the electronic scale, which may be the fault of the load cell:

1. The electronic scale does not display zero, and the display screen flashes constantly.

2. After the electronic scale displays zero, the weight is added and the weighing number is not displayed.

3. When the electronic scale is unloaded or loaded, the displayed number is unstable, drifting or jumping.

4. The weighing of the electronic scale is not accurate, and the weighing number displayed is inconsistent with the number of weights added.

5. The repeatability of the electronic scale is not good, and the same weight is added, sometimes the weighing is accurate, and sometimes the weighing is inaccurate.

All of the above phenomena can be the fault of the load cell. The sensors to be judged are removed from the system separately, and the input impedance and output impedance are measured separately. The normal value of the input impedance of the electronic scale sensor is about 400, and the normal value of the output impedance is about 350, if the measurement data is not within this range, the sensor has been damaged.

If there is a broken circuit in the input impedance and output impedance, you can first check whether the sensor signal cable is disconnected, and when the signal cable is in good condition, the sensor strain gauge is burned, usually because of a large current entering the sensor. When the measured input impedance and output impedance value are unstable, it may be that the insulation layer of the signal line is broken, the insulation performance is reduced, or the sensor is damp, so that the bridge is not well insulated from the elastomer.

Can the question be fixed?

Question Okay, thank you.

Check whether the sensor circuit is damaged and the interface is loose.

If it's okay, open the junction box and check if the sensor output is normal.

If sensor detection is no problem, it's time to consider the weighing indicator itself. Re-calibrate and try again.

The weight unit should be adjusted.

The scale is used without calibration, just find the manual and recalibrate (calibrate).

This is the sleep function of the electronic scale, when not in use, the electronic scale will be put into a sleep state, in order to reduce power consumption, prolong the use of time, the common pricing scale will display a "-" means that it has been put into a dormant state.

Generally, when the weight of the electronic scale is 0, it will turn into a dormant state in about 5 seconds. Different scales are not the same.

The minus sign is a minus, just peel it to zero.

As long as the electronic scale is placed smoothly and booted, it is generally zeroed, and very few do not return to zero, and should be recalibrated.

According to past experience, your situation is not 7 kg, but the display is faulty, or it is missing. In other words, it should be displayed, but because 0 is missing some strokes, it looks like 7, the verification method is very simple, after the boot self-test is completed, whether the display is or lightly press the weighing pan, gradually increase the force. If the weight is above it, the display screen is missing, and if it is above, it is the fault you said.

It needs to be recalibrated, in short, your scale is problematic, it is recommended to send it for repair.

Are you saying that the scale will show the weight when you buy it?
