Info

Page 4 The <strong>FlowCERT</strong> can be programmed either by the built-in keypad or by PC via the RS 232 Serial Interface (optional). All the parameters are stored in non-volatile memory, so are retained in the event of power interruption. A second backup copy of all parameters can also be retained in the <strong>FlowCERT</strong>, in case a previous set of parameters needs to be restored.
