11.3.1 Rate per Day Data logging
Programming Rate per Day Data logging
1.
Select the Logger Program menu (
→
→
→
→
F3:Logger F5:Program
)
2.
Select
F1:Rate per Day
from the menu.
The display should now look similar to that shown below. The current Rate per Day is
displayed…
Number of Readings per Day : 24
3.
Use the Numeric Keypad to set the number of readings per day which the
90-FLMV
will
automatically log into memory. This can be set from 1 to 288 (ie. 1 reading every 24 hours to
1 reading every 5 minutes).
Press
to save the Rate per Day.
Press
to quit without changing the current setting.
4.
The Rate per Day data logging is now programmed, and can be started and stopped as required.
Notes
1.
The
90-FLMV
distributes the number of readings evenly throughout a 24 hour clock cycle,
regardless of what time automatic logging is started and stopped. For example, if the
90-FLMV
is programmed to log 4 readings per day, they will be logged at 24:00, 6:00, 12:00 and 18:00
o’clock.
Starting and Stopping Rate per Day Data logging
Starting Rate per Day data logging is a two step process…
1.
Select the Logger menu (
→
→
→
→
F3:Logger
)
Select
F4:Start
from the menu.
2.
Switch the
90-FLMV
OFF.
This step is essential, as the Rate per Day data logging is only enabled when the
90-FLMV
is
switched OFF.
Stopping Rate per Day data logging is a one step process…
1.
Select the Logger menu (
→
→
→
→
F3:Logger
)
Select
F4:Stop
from the menu.
Notes
1.
The
90-FLMV
remains dormant between readings and only switches itself ON when a reading
is due.
2.
If the Dissolved Oxygen stirrer is enabled, it is switched on for 40 seconds before the reading is
recorded.
3.
The
90-FLMV
is switched on 3 minutes before the next reading is due to ensure that the
Dissolved Oxygen sensor is fully polarised. The unit will therefore not automatically log any
readings for at least 3 minutes after it has been switched OFF, even if a reading is due during
that time.
