3.7.6 Selecting a storage location for PurgeScan Log Files
When saving the PurgeScan Logs, the user has the choice to save the files to either the internal memory of the
tablet, or onto an SD if installed in the device. Under the
Tablet/Phone
menu the button will show either
Use
Phone Storage
or
Use SD card if available
, the selection that is currently shown when the
Tablet/Phone
menu is
open, is where the logs will be saved.

4. Technical Notes
4.1 Dissolved Oxygen
4.1.1 Oxygen Solubility in Water
The function used to calculate oxygen solubility is based on the oxygen solubility vs. temperature data from
Table 4500-O found in the 19th Edition of Standard Methods for the Examination of Water and Wastewater
4.1.2 Salinity Correction of DO mg/L
The function used to calculate oxygen solubility is based on the oxygen solubility vs. chlorinity data from Table
4500-O found in the 19th Edition of Standard Methods for the Examination of Water and Wastewater.
Note
: DO %Saturation is not a function of solubility, and has no salinity or temperature correction.
4.1.3 Barometric Pressure of Functions
Local barometric pressure, BP, in mmHg can be estimated using: BP = 760- 2.5(A/100) where 'A' is the local
altitude above sea level in feet. If using the local weather bureau BP, remember these numbers are corrected to
sea level. To calculate the uncorrected atmospheric pressure BP', use the following function:
BP' =BP-2.5(A/l00)
