Change Datalog Setting
The monitor calculates and stores the gas readings at specified
intervals, which can be reviewed by the user. Users may also program
additional datalog options for the monitor through the computer.
Clear All Data?
Erase all data stored in the non-volatile memory, but does not delete
the PEAK, MIN, STEL, TWA displayed values, which are stored
separately.
Change Datalog Period?
Program the datalog period from 1 second to an hour (3,600 seconds).
Select Data Type?
Store either the average (TWA) or peak value for each datalog interval.
If peak values are selected, average values like STEL and TWA will not
be selected.
Enable/Disable Datalog?
Enable or disable the datalogging function for each sensor. If a * is
displayed next to a sensor name, data will be recorded. Use
M
to move
from sensor to sensor. An asterisk (*) means the sensor is enabled; no
asterisk means the sensor is disabled. Press [Y/+] to select or press
[N/-] to deselect. To save changes, press
M
until “Save?” appears.
Then press [Y/+] to accept. Otherwise, hold
M
to escape and cancel
changes.
Select Memory Full Type?
The instrument’s memory can store about 3 days’ worth of data, as a
result of continuous monitoring at 1-minute intervals. Users may select
one of two types of memory storage:
Wrap-around
: after the memory becomes full, the latest data
overwrites the oldest data. e.g. the most recent 3 days’ worth of data
is stored.
Stop:
halts datalogging when the memory is full, and the “MEM”
alarm sounds. e.g. the first 3 days’ worth of data is stored.
