A and B Channel Zero Shift
To compensate for any offset at zero enter appropriate values for the Zero Shift
values (see the Inclinometer Probe manual and Calibration sheet for more
information). Digital probes may have these values programmed at the factory.
When the probe type is set to Compass, the Zero Shift A value should be set to
200 (see Figure 72). See Appendix H for more information regarding Spiral
Indicator Probe operation.
-
A and B Channel Gage Factors
Using the on-screen keyboard, enter appropriate numbers for the 2 gage factors
(see the Inclinometer Probe manual and Calibration sheet for more information).
Digital probes may have these values programmed at the factory. When the
probe type is set to Compass, the Gage Factor A value should be set to 0.1 (see
Figure 72). See Appendix H for more information regarding Spiral Indicator Probe
operation.
-
A and B Channel Gage Offsets
These values are typically “0” and are occasionally needed to remove an offset
from a Compass probe. Offsets are entered in engineering units using the on-
screen keyboard (see Figure 72). For a Compass probe there will be no “B”
channel and the B Channel value should be left at “0”. Digital probes may have
these values programmed at the factory.
When the probe type is set to Compass, the offset can be determined by taking
readings (using the Live Readings screen) and determining if the compass value
is ever greater than 360. If so then the Gage Offset A value should be set to 360
– (current reading > 360). For example, if the current compass probe reading is
365 then the Gage Offset A value = (360 – 365) = -5. See Appendix H for more
information regarding Spiral Indicator Probe operation.
If the probe “Type” is set to Tiltmeter, the “B Channel” parameters are not used and
can be left at 0. When done editing, the settings can be saved via the “Menu->Save
Settings” option.
If connected to a digital Remote Module and digital probe, Zero Shift, Gage Factor
and Gage Offset changes can be uploaded to the probe via the “Menu->Save and
Upload Settings” option. After tapping “Save and Upload Settings”, the reminder
window shown in Figure 38 will be displayed to ensure that the Remote Module is
ready to connect.
