Direct Read
Note: In "Log Time" mode the dipperLog increases the readings from 1 second by an additional 1 second for 255 readings. The final reading interval is 4 min. and 14 sec. and the logger then stops logging. This mode logs for a total of 9 hours before stopping.
Barometric Compensation The first reading can be used for all readings unless a barLog is used. Automatic compensation when using a designated barLog. Manual compensation in Excel.
