9.3 Automatic Datalogging
The
90-FL
can automatically log records into the Logger. There are three automatic datalogging
modes to choose from…
1.
Rate Per Day
•
Logs from 1 to 288 readings per day, evenly spaced throughout each 24 hour period.
•
Unit is dormant between readings and “wakes up” when a reading is due.
•
Dissolved Oxygen stirrer is switched on for 40 seconds before each reading is logged (if
Dissolved Oxygen stirrer output is enabled).
•
Unit continues to log until automatic datalogging is disabled, or until the memory is full.
2.
Time of Day
•
Logs at up to12 discrete times of the day, which can be unevenly spaced throughout each 24
hour period.
•
Unit is dormant between readings and “wakes up” when a reading is due.
•
Dissolved Oxygen stirrer is switched on for 40 seconds before each reading is logged (if
Dissolved Oxygen stirrer output is enabled).
•
Unit continues to log until automatic datalogging is disabled, or until the memory is full.
3.
Sampling Period and Duration
•
Logs a reading every 1 to 300 seconds for a duration of 1 to 720 minutes.
•
Duration can be set to log continuously until the memory is full.
•
Unit is turned on continuously in this logging mode.
•
Dissolved Oxygen stirrer is switched on continuously in this logging mode (if Dissolved
Oxygen stirrer output is enabled).
The automatic datalogging parameters of the
90-FL
must first be programmed, then logging can be
started and stopped as required.
