Why did the water meter suddenly stop IC?
Whether the card is inserted correctly; whether the water meter shows the word "ICOK" or "PASS" after inserting the card.Whether the water meter is short of power; if the power fails, the water meter LCD screen will show the word "power shortage".Whether the front valve of water meter is opened and whether there is water in the pipeline.
The correct operation of the user card, to see whether the water meter valve can open; if you open the valve at this time, there are two possibilitiesMargin less than the alarm water, you can ask the management center, whether the software set up water meters, alarm volume is too high, the alarm in the water meter, the valve only need to operate the user card, you can open the valve water;The last purchase of water did not normally import water meter. The amount of water into the normal recharge representation: in the card process, the meter will appear corresponding amount, and the cumulative purchase allowance, purchase amount is the balance of the card into the water, into the card quantity and order before the table of allowance;
The phenomenon of money off valve is the remaining money in the card list, less than the warning valve, but the card table valve automatically closes. There are many reasons for this phenomenon. First of all, it is necessary to exclude whether due to pipeline reasons, such as jitter or strong magnetic attack table, resulting in automatic shutdown of the meter. There is also a card board of your house, the chip is damaged by damp, need to replace a circuit board module, I have been a water meter for many years, you have seen such a lot of examples
