Data logging connection

The following logging parameters for up to 20 measuring points can be transmitted to a
personal computer:
• On line data
• A maximum of 40000 data points (time, velocity, flow rate, totals, analog input, status)
can be stored in the data logger's memory
When using a personal computer for data logging, use an RS-232C cable for serial
transmission between the RS232C connector of the personal computer and the
"SERIAL" connector (see Fig. below) of the flow transmitter.
