SECURITY SETUP
The security features of the pH meter series F aim to prevent irresponsible revision or deletion
of set or measured data stored in the meter by a third person. Therefore, changes by a third
person without authority are not available for date change, data memory deletion, or security
related setting change.
The meter can be used without operator registration. In that case, this section can be skipped.
When the operator is not selected by selecting OFF in SELECT OPERATOR, the operator
name “*GUEST*” is automatically selected.
There are two levels of operator: Administrator and Operator.
In user control functions, the configuration of each setting item is as follows:
