[F30] Accumulated value hold setting
This function enables the accumulated flow value to be stored in permanent memory every 2 or 5 minutes.
In the default setting, the accumulated flow value is not held when the power supply is turned off.
: When using the accumulated value hold function, calculate the product life from the operating conditions, and use the product within
its life.
Maximum updating time of the accumulated value is 1.5 million times.
If the product is operated 24 hours per day, the product life will be as follows:
•
Data memorized every 5 minutes --- 5 minutes x 1.5 million times = 7.5 million minutes = 14.3 years
•
Data memorized every 2 minutes --- 2 minutes x 1.5 million times = 3 million minutes = 5.7 years
If the accumulated flow external reset is also repeatedly used, the product life will be shorter.
