This option displays a range of times that allow
the user to decide how often the readings need
to be logged. The times range from 5 seconds
to 1 hour. Use the scroll keys to select then

4 - 20mA Output KEY
The 4-20mA can be set to the maximum flow
rate. It is also possible to enter a negative
figure for the minimum output and would
enable a reverse flow to be monitored. The
4mA would then be the maximum reverse flow
(e.g. -100 lpm) and the 20mA would be a
maximum positive flow (e.g. 100 lpm).
mA Out
This displays what the current output is giving
at any particular time.

Flow at Max Output
This sets the output at the top end of the scale
so that the maximum flow gives 20mA (or
16mA).
The instrument automatically defaults to the
maximum flow rate, but by pressing ENTER
the user can scale the output to any level
required. When selected press ENTER to
continue.
