4.5. Change Datalog
The QRAE PLUS monitor calculates and stores the gas
readings at specified intervals. The user can change the datalog
setup in the programming mode. Users can also program
additional datalog options using a PC and download them to the
monitor (see ProRAE Suite Manual for details). The sub-menus
for datalog options:
Clear All Data?
Change Datalog Period?
Select Data Type?
Enable / Disable Datalog?
Select Memory Full Type?
1. “Clear All Data?” will clear all the data in the datalog.
2. “Change Datalog Period?” allows the user to log the
concentration readings every 1 to 3,600 seconds.
3. “Select Data Type?” allows the user to choose if the peak or
the average reading in the datalog period will be stored.
Note: The QRAE PLUS monitor generates one
concentration reading every second. If the datalog period is
900 second (15 minute) and the data type is average, the
QRAE PLUS will calculate the average of 900 readings and
store it to the memory every 15 minutes.
4. “Enable / Disable Datalog?” will activate or suspend the
datalog function. The asterisk (*) next to the sensor’s name
means that the datalog function is enabled for that sensor.
By pressing the
[Y/+] or [N/-] key, it will activate or
deactivate that sensor’s datalog function.
5. “Select memory full type?” allows the user to decide how
the data are stored. Two options are available when the
memory becomes full, either the memory begins to “wrap
around,” overwriting the oldest data, or it can “Stop” storing
any more data. Follow instructions on the display and use
[Y/+] , [N/-] and [MODE] to perform desired functions.
