3.6.2 How to set up the basic logging application to memory
This procedure shows you how to set up a basic logging session under manual start/stop control. The logged
data is saved to the instrument’s memory and can be downloaded to a PC at a later time.
Starting point
This procedure assumes that the Portaflow has been correctly installed and is operating in the FLOW READING
mode.
Setting up and starting the logging
1. With the Portaflow now operating in FLOW READING mode, check that the indicated flow units are the same
as those you want to appear on the logger output (e.g. l/min).

Logging to memory message should appear on the

events in date-stamped chronological order.
Note:
Press key 5 to go to the top line of logged
data or key 6 to go to the bottom line.

FLOW READING screen. Logging will continue to
take place in the background.

There can be only one set of logged data per site. If a new data log is
started on a site it will clear the existing data.
