It is always recommended to use the cable gate supplied with the system as it not only protects the cable from damage it provides the most accurate and repeatable readings.
On installations deeper than 40 metres it is recommended to carry out a spiral survey using a spiral probe. The data can then be inputted within Inclinalysis software to correct any spiral effects
Basic operation tips
The A axis is defined as the direction of expected movement. If it has not already been done identify the A axis on the casing and clearly mark it.
Always fit the cable gate onto the top of the casing.
Take the first set of readings is taken in the A+ direction. This is the orientation of the casing groove into which the leading wheel of the inclinometer probe is located.
Lower the probe to the bottom of the casing and allow it to stabilise for a few minutes.
Raise the probe at 500mm intervals resting the cable grips in the cable gate each time.
The readout has a visual stability scale on the left of the screen. Once the scale shows maximum stability the reading should then be confirmed on the PDA.
Once the probe has reached the top remove it from the groove and rotate it 180º and lower again to the base of the casing and repeat the survey.
Getting the data from your Inclinometer
Data is stored within the Rugged Field PC handheld readout and can be downloaded via the USB or RS232 ports. The data is in a simple CSV format which can either be manipulated using Excel or imported into Inclinalysis software.
Verifying your results
Checksums can be viewed on the Rugged Field PC handheld readout during the survey so that the quality of the data can be verified.
Do I need to use the same probe to survey the same hole?
We believe in being realistic and practical about the levels of accuracy that should be expected and can be achieved on a working construction site. Although every Inclinometer probe leaves the factory with the same accuracy specifications they are unique and acquire individual characteristics over time as a result of many factors.
Therefore we would concede to get the “perfect” results it would be “ideal” to use the same probe. However since this isn’t always possible especially if they are hired so we support the practice of using different probes but having consistency in the taking of the readings.
