3.6.5 How to log directly to a PC
Selection made during logging set-up
Swapping data destinations during a logging session
When a logging session is in progress the PUF is normally in the FLOW READING mode. In this mode you can
switch the logging data destination by pressing the Logger function key and then selecting either Memory or
Comms in the Log data to field – see the screen above. You can also select Both, to route the data to both
destinations simultaneously.
1. In the previous procedures the logging data was
routed to the PUF’s internal memory where it
was stored for later download to a PC/printer.
However, you could have sent it directly to the
PC or printer for ‘live’ data display by selecting
Comms in the Log data to option in the REAL
TIME LOGGER screen.
2. In order for this to work correctly, the PUF must
be connected to the PC and the RS232/USB link
already established.

Key Point: This will only work if the PUF is connected to the PC and the RS232 link has
already been established. If the RS232 protocol has not been configured, you can
access the RS232 set-up screen by returning to the FLOW READING screen and then
pressing the Comms button.
