Data Integrtity and Built-in Time-keeper

 

All user-inputted configuration values are retained in the built-in non-volatile flash memory that can store them for over 100 years, even if power is lost or turned off. Password protection is provide to avoid inadvertent configuration changes or totalizer resets.

A time-keeper is integrated in flow meter for the index of date totalzing and works as the time base of flow accumulation. It keeps operting as long as the battery's terminal voltage is over 1.5V. In case of battery failure, the time-keeper will not keep running and it will lose proper time values. The user must re-enter proper time values in case the battery bacomes totally exhausted. An improper time value affects no other functions but the date tatalizer.

 

Product ldentification 

Each set of the TUF-2000H has a unique product identification or ESN wirtten into the software that can only be modified with a special tool bythe manufacturer. In case of any hardware failure, please provide this number which is located on menu window number M61 when contacting the manufacture.
