6.3.4 DATALOG
The instrument automatically stores the concentration readings at regular time
intervals (this function cannot be turned off). In the datalog sub-menu, a user can
adjust the interval or clear all data. Press Right to enter the Datalog menu.
Clear Datalog
This erases all the data stored in the datalog.
CAUTION: Once the data are cleared, they cannot be recovered.
6.3.5 MONITOR (MNT) SETUP
Several settings can be accessed here, including date and time, pump parameters, display parameters
and selecting 3-point calibration.
Date and time
This erases all the data stored in the datalog.
CAUTION: Once the data are cleared, they cannot be recovered.
1. Press the Right key to clear the datalog. The display asks, ‘Clear Datalog?’
2. Press the Left key if you do not want to clear the datalog.
3. Press the Up key if you want to clear the datalog. When it has been cleared, the display shows ‘Datalog
Cleared!’ and moves to the next sub-menu, Interval.
Interval
Intervals are shown in seconds. The default value is 60 seconds and the
maximum is 3600 seconds (1 hour). There is enough data capacity to run for
6 days at 1-second intervals, 12 months at 60-second intervals, or 6 years at
10-minute intervals. Once the datalog is full, it cycles and begins to replace
the oldest data.
To change the Datalog Interval, press the Up or Mode key to increase or decrease each digit’s value, and
the Right or Left key to move the cursor. Then move the cursor to ‘√’ and press Up to save and exit.
