ALL or RETAKE SINGLE button for that reading. The two retake options are defined as
follows:
•
RETAKE ALL requires that the user retake all readings from the retake depth to the
top of the borehole.
•
RETAKE SINGLE requires that the user retakes just the reading of the selected
depth and the app resumes from the current depth.
The user is prompted to confirm the re-take reading request.
Axis A- Take Readings Process
– Second Pass
The depth reading continues until the probe reading reaches to the top depth. Once the top
of the hole has been reached, the Digital Inclinometer app prompts the user to turn the probe
180
o
and lower it back to the bottom of the hole. This is the Axis A- reading.
The Digital Inclinometer app starts the Axis A- depth at the lowest borehole depth. The Axis
A- depth reading is similar to the Axis A+ depth reading, but a new checksum data field is
visible.
The checksum data appears to the right most column preceded by a delta symbol. The real-
time checksum value allows the user to monitor the second set of readings. If the checksum
is large or inconsistent, either the probe has fouled or the probe is not at the correct
measurement depth. Similar to the Axis A+ procedure, the user continues to take readings
until the top of the borehole is reached. If the probe is accidentally raised above the
measurement point, the probe should be lowered back down below the proper depth and
then raised slowly to the correct depth. This ensures consistent and accurate readings.
Figure 20 shows a sample Axis A- reading at the bottom depth and the Axis A- reading at
the top depth.

If the user deems any of the previously accepted readings on the Axis A- is improperly
taken, the user may request a re-take on any depth. The user lowers the probe to the re-take
depth. On the Digital Inclinometer app, the user scrolls to the depth and taps the RETAKE
ALL or RETAKE SINGLE button for that reading.
Once the top depth is reached on the second pass, the Digital Inclinometer app displays a
prompt indicating the reading process is completed and the readings are automatically
saved in
the device’s memory.
