• Live temperature - if Live Analog was selected for Temperature for meter corrections on
the Daniel MeterLink Startup Page, enter the scaling for the transmitter connected to
the analog input. Minimum input is the zero scale temperature of the transmitter (i.e. 1
Volt or 4mA). Maximum input is the full scale temperature of the transmitter (i.e. 5
Volts or 20 mA).
