Settings are saved as they are changed so the SET button may be pressed to go to another set screen without pressing any
other ey to save the setting.
LOG A DEPTH READING: Press the LOG button to record a reading for that point in time. The display will show “Logging”. Do
not remove the probe or press buttons until the depth is again displayed. This information is added to the data log (if enabled.)
Press DISP to view the data, and then the up or down arrows to scroll through the data. Press the ENTER ey to display
additional data for any point.
POWER OFF: Press the OFF button located on the front panel of the control unit. All system settings as well as the time and
date, and log data are maintained while the power is off.
D SPLAY MODE DESCR PT ONS
DEPTH DISPLAY –The default display mode after power-up. While this display is active, the unit is operational, sending pulses
and timing the echoes. The depth is displayed on the top line and additional user selectable information is displayed on the
second line. The depth is displayed as “searching” when the unit is turned on and adjusting to the well. Once the signal is loc ed
and stable, the depth is displayed in the units selected. Occasionally a spurious depth reading will be calculated due to random
noise in the well. Software in the well sounder identifies the anomaly and holds the last good data through a few bad data points
while a good depth is obtained. An asteris is displayed before the depth while holding. If a stable depth is not found in several
tries, the depth is replaced with “searching” until one can be found. Data displayed on the second line can be changed by
pressing the up or down arrow. Data available varies depending on options enabled on each unit. If there are any error
conditions, such as when the probe is not on the well or is missing, or when the battery low, an error message will alternately be
displayed on the second line.
PROBE – displays the temperature measured by the probe. This temperature is used to automatically compensate sound speed
variations due to temperature in the upper part of the well.
WATER – displays the total water in the well in gallons (liters) calculated from the entered well diameter, well depth, and the
measured depth.
RATE – displays the rate of change in gallons/minute (liters/minute) calculated from changes in the total water in well over time.
The rate is calculated using an averaging technique on the last 20 measurements to stabilize the reading. Press the ENT button
to reset the average to an instantaneous reading. As additional readings are obtained, they are automatically added to the
average bac up to the last 20 points.
FLWTOT – displays the total water pumped through the optional flow meter in gallons (liters) when enabled. The flowmeter is
plugged into the probe connector with the probe using a splitter. Press the ENT button to reset the total to 0.
FLWRATE – displays the rate through the optional flow meter in gallons/minute (liters/minute) when enabled. The flowmeter is
plugged into the probe connector with the probe using a splitter.
RECOV – displays the recovery rate of the well by subtracting the flow meter flow from the change in the calculated water in the
well.
BAT – displays the measured voltage of the battery or external power supply if used. The well sounder maintains calibration
down to 6.5 volts. An alarm is displayed when the voltage drops to 6.5 volts. The unit will continue to operate, but with reduced
signal strength down to about 5.5 volts.
DIAGNOSTIC DISPLAY – One of the data options on the DEPTH DISPLAY mode shows four numbers on the second line: the
first two numbers indicate the quality of the pulse. These numbers should be in the range 20-60 for a good signal and the first
should be larger than the second. If the second is larger, it may indicate that the unit is loc ing on to an erroneous reflection from
a brea out in the well, or that the top of the well is not closed tight enough. The second two numbers indicate the unit’s gain. A
larger number indicates a wea er signal and for a good signal should be in the range of roughly 600-680. The first of these
numbers is for the transmitted pulse, the second is for the returning pulse. The first should be larger than the second. If not, it
could indicate that the well is deeper than the range, the probe does not have open access to the well shaft, excessive noise in
the well or a problem with the probe itself.
