DH-21
Using the Graphical “W ATER LOG” Software 4-7
will cause the sensor to record levels with a -5.0 foot offset. The logged value is
based on the following equation:
Logged Level = True Level - Offset
All components of the equation must use the same units such as feet.
This option also allows you to easily remove any error in the pressure
measurement due to long-term offset drift.
[S]ensor Info:
This option is used to view specific sensor information not related to the operation
of the unit. This includes serial numbers and model numbers.
[F]ile Options:
This option is used to save and retrieve setup files. If a sensor is attached and a
setup file is retrieved, the setup file will be loaded into the PC and into the
attached sensor.
[A]ttach:
If a sensor is physically connected to the PC, this option is used to set up the
software to communicate with the sensor.
[D]iagnostics:
This option is used to perform tests on an attached sensor. This will clear out the
data memory, user notes and some other options. This is normally used only if
there seems to be a question on the performance of the sensor.

[Q]uit:
This is used to exit the program and return to DOS.
