Troubleshooting

It is not uncommon for clients from all territories to call the WinCan support teams with questions about their data reports.

The most common issues seen are a lack of understanding of what data is being presented and bad equipment setup, most often bad (or no) calibration.

Everything that is needed to understand these problems is included in the text of this manual, but as a first port of call, support teams and clients should look carefully at the following data while trying to figure what is happening or why the graph ‘looks’ wrong:

The section header data - look closely at:
- The pipe depths and pipe altitudes above sea level.
- The inspection direction.
The inclination test direction - in the inclination panel look at the green and blue arrows and which end of the horizontal axis of the graph has the zero value.
The vertical scales - understand what they are showing you and compare them with the data values at the top of the panel.
The inclination curve - this is probably the most useful piece of information because it is not linked to the altitudes and shows you the actual data points that have been recorded during the test. This is usually the easiest way to get a ‘feeling’ for if the calibration is really bad.
The data points - these can also give you a ‘feeling’ of what is going on by scrolling up and down the list you can see if the majority of the points are negative or positive which will help to diagnose problem graphs.
The ‘Fit to Altitudes’ button - this can make a bad graph look good but it only hides the fact that the data is bad in the first place and is only available if the vertical altitude values of the pipe are in the header data.
