VII.                             Operation Instruction

(1). First, user purchases the gas at gas supplying department, then after inputting a certain tolerance to the radio frequency fuel gas card. Let the induction zone on the card match together with the induction zone at the left of meter panel bottom. When hears a sound of du, then inputting program is finished. (If occurring the wrong reading card, user shold reciprocate radio frequency card on the induction zone till hear a sound of du inputting program completed). And then ake out the card and safekeeping it for the next time purchase gas and writing card. The LCD screen displays Residual Tolerance and automatically opens the value.

(2) Under the front lower part of the meter, let the induction frame of te meter match together with the induction zone of panel, take out the card when hearing a sound of Du.

(3) When displaying the Deficient Electric Quantity, taking the battery case out from the front lower part of meter. After exchanging the battery, inserting the battery case as per the original direction and tigten the fixing screw.

(4) When displaying the DeficientAllowanct, let the radio frequency card match together with the nduction zone or purchase gas in time.

VII.            Points for Attention

(1). This meter is provided with one meter one card system. The card should not be used by exchanging each other between meter and meter; otherwise, radio frequency card will be damaged all its life.

(2). Close the valve when used up the tolerance, before repurchasing gas and inducting card, all fuel gas device and valve must be in closing state, just for in case.

(3) It should be maintained by professional technician when occuring fault on the fuel gas meter. Do not disassemble personally.

(4)If fuel gas leaking, please open the window and the door and close the valve immediately. It is forbidden to use open flame and portfire tools at that time. The user should contact with the fuel gas company in time.

(5). The surface of the fuel gas meter should be kept cleanly. If there is some smudge and dusk on the meter, it should be cleaned by dry moist cloth.

VIII.                        Maintenance and Keeping

Fault symptom	Analysis of Causes	Remove Methods
Gas can not be used	1. Inadequate battery voltage	1. Change battery.
	2. Without tolerance	2.Repurchase the gas with radio frequency card input the fuel gas meter
	3. Illegal operation or magnetic interference;	Induct the card or recharge the electricity, if it has tolerance. It will open the valve automatically.
	4.Lower than the limited tolerance(namely the residual gas of the meter<=2 m3 )	Induct the card or recharge the electric automatic valve to use up all the tolerance, then shut the valve
	5. Other problems	5. Contacting other related personnel to deal with.
Liquid crystal cannot be displayed	1.Deficient tolerance;	1.Change the battery immediately;
	2.Exceed the operating environmental condition;	2. Operate successfully within the limited environmental condition;
Alarm automatically	1.Deficient tolerance	1.Purchase the gas wit radio-frequency card.Input the fuel gas meter;
	2.Inadequate battery voltage;	2. Change he battery immediately;
	3.Magnetic interference;	3.Induct the card or recharge the electricity (automaticaly valve recovers gas supplying);
Continuously alarming afer matching together the inductive card.	1. Radio frequency card is not for this system;	1.Using the radio frequency card published by this system;
	2.Illegal operate radio frequency card, such as the induction zone has not matched together, inserting card at inverse or have not put the right position;	2. Correcly operate accordin to the presentation, just put it on any position on the induction zone, it can read card;
	3.Without tolerances in the card;	3.Purchase the gas with the radio frequency card, then input it( if there is no tolerance, the inductive card will display the accumulative tolerance;
	4.The sum of purchasing tolerance inside the card and the socking tolerances of fare register exceeds 2000 m3	4.Make the meter use on the normal condition for a while when the tolerance sum is less than 2000 m3, then induct the card.
