The Solinst Levelogger Gold PC Software is intuitive and user-friendly. The simple Windows® based software allows you to easily customize and manage data to meet your own requirements. A key feature of the Levelogger Gold Software is the ‘Data Compensation Wizard’. Most users are familiar with Barometric Compensation and Density Adjustment, but may overlook how useful the Manual Data Adjustment can be.
The Manual Data Adjustment allows you to use the ‘Reference Datum’ field to adjust your data to top of casing or sea level for instance, simply by replacing the datalogged water level reading with a manual water level measurement. The program then computes a correction factor using the reference datum and adjusts all of the data in the file to this new zero point. This adjustment is performed after barometric and density compensations have been performed.
It is important to remember, if the reference datum is above the water level reading (e.g. top of well casing), the datum must be input as a negative value. If the reference datum is below water level (e.g. sea level), a positive value is input.
For example, if the manual water level measurement shows that the water level is 5 ft (1.5 m) below top of casing, then you would input the Reference Datum as a negative number -5 ft (-1.5 m). Subsequently a pressure reading of -4 ft (-1.2 m), for example, would indicate that the water level was 4 ft (1.2 m) below top of casing.
