3

Accumulated flow

Forward cumulative measurement, reverse cumulative measurement, settlement cumulative flow.

4

Initialization

clear the measurement parameters or reset to default

Impact parameters refer. 2.3.3

5

Correction time

Correct anytime without leap year

2000 year~2100 year,

Minimum correction to seconds

7

Battery voltage detection

Alarm when the battery voltage reaches the lower limit

8

Remote diagnosis
