■[F30] Accumulated value hold
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. The maximum access limit of the memory device is 1 million cycles. 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 million times = 5 million minutes = 9.5 years
Data memorized every 2 minutes --- 2 minutes x 1 million times = 2 million minutes = 3.8 years
If the accumulated flow external reset is also repeatedly used, the product life will be shorter.
