Function introduction

No.	Function name	Function brief introduction	Function parameter
1	Measurement	Using multiple signal sources combination to calculate technic and software anti-interference technology, can check the true  and false of the signal
2	Meter number management	The only identify number of each meter, can only be modified by specialized machine	14 decimal numbers: 000000000000-999999999999
3	Meter base number management	If the water meter has a mechanical counter, the electronic readings and mechanical readings should be consistent.	0000.0000 cube-9999.9999 cube
4	Correction time	Correct anytime without leap year	2000 year~2100 year, Minimum correction to seconds
5	Reading on assigned day	Save measurement data for a specified day
6	Failure testing	Alarm when strong magnetic interference or short-circuited on sampling line
7	Battery voltage detection	Alarm when the battery voltage reaches the lower limit	The lower limit is based on voltage value, generally lower 0.2~0.4V than battery voltage
8	Remote diagnosis	Meter reading,battery voltage,specified day reading,Failures,Valve Status,balance,Magnetic interference status	remote diagnosis available whenever necessary
