4-26 Using the Graphical “W ATER LOG” Software
DH-21
Note: It is important to program these values correctly. The data displayed in the last measurement
window will reflect the scaled value. The “
W ATER LOG” performs scaling math to the measurement
before it is stored into FLASH EEPROM. Also, the extracted data from the “ W
ATER LOG” sensor
will reflect the scaled value.
Temperature:
The standard choices are Celsius and Fahrenheit. Again, if one of the standard choices is
used, the conversion factors are setup automatically. If the standard choices are not
usable, the “User Defined” option can be used to enter in a more appropriate conversion.
Pressure Compensation:
The options here are “User Defined” and “Default”. In most cases, selecting “Default”
will provide sufficient accuracy, however, the accuracy may be increased by selecting the
“User defined” and entering in the requested information.
