4. Create a new hole configuration for every unique location where tilt is to be
measured:
•
Using the Context Menu (see section 3.2.1), after highlighting the Project
element, select the “Add Hole” menu item to create a new hole configuration.
•
Since the “hole” corresponds to a physical location, be sure to name it
appropriately, such as, “Location1”.
•
Additional information may be entered in the “Description” field.
•
For each new hole created, select the probe created in step 3.
•
The hole parameters such as “Starting Level”, “Interval”, “Top Elevation” and
“Azimuth Angle” are not applicable for Tiltmeter operation and can be left
blank.
•
Tap “Save Settings” to save the new hole configuration. See section 4.1 for
more information about hole configuration.
5. Make sure that the “hole” corresponding to the location to be measured is
selected in the Project Explorer.
6. Press the “POWER ON” button on the GK-604-4 interface and ensure that the
blue indicator is blinking.
7. Tap the Live Readings menu item from the Application menu to start the reading
process. If a valid Bluetooth connection can be established, a Tiltmeter specific
Live Readings screen will be displayed (see Figure 80).
Note the drop-down control in Figure 80, located just to the right of the “A” value
display. This allows the “A” value to be displayed in 3 different units, described
below:
Digits Digit values are calculated as follows:
R1 = Probe Voltage (PV) * 2000
[R1 is read from the Remote Module]
R0 = Zero Shift A [from probe configuration]
GF = Gage Factor A [from probe configuration]
GO = Gage Offset A [from probe configuration – usually zero (0)]
DIGITS = ((R1 – R0) * GF) + GO
Volts PV = (R1 – R0) / 2000 [for Geokon probes: +4V
≈
+15 degrees]
Degrees DEGREES = arcsin( ((R1 – R0) / 20000) * GF ) [multiply by 180/Pi
if arcsin produces angles in radians]
