You need to replace the battery of the cooker regularly, otherwise the cooker with its own flameout protection device will not be able to use properly and safely, and the battery replacement cycle is 3-5 months.

If natural gas leaks occur, do not use open fire. Natural gas can easily mix with air to form an explosive mixture with an explosion limit of 5% to 15%. When a natural gas leak occurs, because it is lighter than air, it will quickly gather in the upper part of the room. At this time, we must first eliminate all fires, quickly close the pipe shutter, then open the doors and windows, and use fans and other items to fan the natural gas floating in the upper part of the kitchen, but do not open the exhaust fan and hood, because it is easy to have an electric fire and an explosion. Then you must notify the gas company's service personnel to come and deal with it.

When coal gas leaks occur, it will give off rotten egg odor. Because its specific gravity and characteristics are largely similar to those of natural gas, the same approach should be taken as for natural gas leaks. The difference is that coal gas is toxic, and when a person inhales 7% of carbon monoxide, he or she will experience symptoms of poisoning and even death. Therefore, when coal gas leaks occur, be sure to wear a gas mask before entering the area where the gas leak is running. If you do not have a gas mask, you should also use a wet towel to wrap your mouth or hold your breath, and evacuate the scene immediately after taking rapid measures.

LPG is the most dangerous when it leaks. Because it is liquid in the cylinder, it will immediately expand 250 times after it flows out. And because it is characterized by the specific gravity, and is not upward floating, but sinking to the ground, gathered in low-lying areas, not easy to float and low limit of explosion. Therefore, after eliminating all fires, close cylinder valves, open doors and windows, sweep the ground with a broom to drive out the leaking LPG to prevent the fire from exploding.

Now gas meters have been applied widely, but some problems inevitably appear during use.

Counting discrepancy/no counting: Gear and micro switch aging or incorrect position; 2. Reed tube failure, resulting in more or less counting or even not counting of the electronic device.

Normally open valve: 1. Low battery power; 2. Reed tube failure caused by its quality or vibration, so that the electromechanical valve can not work.

Normally open valve (no gas, meter blockage): 1. The card is improperly inserted; 2. Meter failure; low battery power;

Long beep: Buzzer damaged

No buzzer: Buzzer short circuit

No card reading: 1. Cardholder oxidation, data line open circuit; 2. Low battery power.

Air leakage (internal leakage, external leakage): 1. Internal leakage: the airtightness of the electromechanical valve when it is closed is called internal leakage. Causes: the valve mouth and the valve cover is not closed tightly, such as burrs or flatness super poor, the valve cover and the valve mouth misalignment or half-open state. 2. External leakage: the air tightness of an electromechanical valve when it is opened is called external leakage. Causes: electromechanical valve push rod and seal ring sealing is not tight; gas gun and valve body connection is not tight; valve body and through and base table connection sealing is not tight.

Please purchase alkaline batteries. They are not only environmental protection, safety, but also avoid your cooker from the risk of damage to the battery.

Replace the battery regularly, otherwise the meter will not be able to supply gas normally. The battery replacement cycle is 3-6 months.

The gas meter will emit a squealing alarm sound when the balance is insufficient. It is a reminder of insufficient balance and the user is required to purchase gas.

The IC card gas meter is currently the most popular smart gas meter. Many users also have some questions for the use of IC card gas meter.

Here are some kinds of situations that IC card gas meter can not be recharged when the card is inserted it:

1. Card inverted or take the wrong card.

2. Insert and remove the card too fast.

3. The card chip has oil stains.

4. There is moisture or foreign matter in the card holder, etc.

5. The card holder is bad.

6. IC card is damaged.

First, the smart gas meter with batteries can not continue to use without electricity. You must replace new batteries with generally four 5 dry batteries. It is recommended to use high quality batteries.
