Datalogging Operation – Mode 3
Datalogging Mode 3 will automatically record data log records using the current
location with the user settable auto log interval (settable to record every 1 to
1800 seconds).
 When the Device is turned on and in RATE or MAX mode, the current
radiation reading and other log data is recorded at the set interval.
 In COUNT Mode:
- Auto log will be paused and will only log at the completion of each
count.
- For a continuous Scaler count (Scaler time is 0), logs will be
recorded at auto log interval.
 The Data Log Table is linear; once the table is full, no further writes will be
allowed until the Data Log Table is erased.
Note:
Tapping the LOG button will start a count and automatically log
the result. Long-pressing the LOG button during the count will
toggle the display between the timer and reading.
