Disp High: This field sets the upper limit of the bar graph displayed in the main
screen and provides a way of scaling the graph beyond the upper limit used to
calibrate the logger. In this example, the upper calibration point was a water level of
8 feet but the maximum range of the sensor is 16 feet.
Disp Low: This field sets the lower limit of the bar graph displayed in the main
screen and provides a way of scaling the graph beyond the lower limit used to
calibrate the logger. In this example, the lower calibration point was a water level of
zero.
Decimal Places: From the pull-down menu, select the
number of decimal places to the right of the decimal
point that should appear in the historical data and in the
numerical data field at the bottom of the bar graph.
Calibrate: The “Calibrate” button provides a simple 4-step process for calibrating
the WL16 Data Logger to a particular sensor. Click the Calibrate button and follow
the menu instructions.
Click on the High EU field and enter the high
engineering unit that will be used to calibrate
the logger, not the highest reading the sensor
can output. In this example of water level, a
depth of 8 feet used to calibrate the logger,
even though the sensor can measure up to 15
feet.
Click Next.
Place the sensor in the condition that will
cause it to output the level corresponding
to the high EU entered in the previous menu.
Wait for the data reading to stabilize.
