I’m often asked whether the Prosig P8000 systems support strain gauges. And what configuration of strain gauge bridges are supported? The answer is all types of all the different configurations. Continue reading Does the P8000 support strain gauges? And which types?3813class="post-3813 post type-post status-publish format-standard hentry category-dats category-signal-processing category-tutorial tag-dats tag-moving-average tag-p8000 tag-trend"
This tutorial guides a DATS user through the steps required to perform a moving average on a given signal. The tutorial explains the concept of the ‘Integration Length’ and the ‘Output Interval Step’.
Initially a signal is required to perform the moving average on. In this tutorial a sine wave will be generated. A sine wave is generated using the parameters shown in Figure 1.

It is possible to enable audio playback to listen to audible frequencies while recording or monitoring when using a P8000 and the V4 Acquisition software.

A question was recently posed regarding the grounding conditions of a BNC type input. The shield or outer of a BNC cable or connector is not connected to the chassis or ground. What would happen if it was connected to ground?
Continue reading Is it possible to connect the BNC outer to ground when using a P8000?3622class="post-3622 post type-post status-publish format-standard hentry category-p8000 category-tutorial tag-data-acquisition tag-p8000 tag-rotating-machinery tag-tacho tag-tacho-signal tag-tachometer"
When using an analogue channel input channel of a P8000, with a tachometer sensor, is it possible to utilise the tachometer processing functions as you would if you were using a tachometer input of the P8000?
For example could you display an RPM on an analogue channel?
When using an analogue channel it is possible to select, from the signal setup matrix, ‘Trigger Type’, with this option set to ‘Tacho’ and the ‘Trigger Level’ set to the voltage crossing threshold several features become available in terms of tachometer processing.
By selecting the above options the user will be able to use the ‘Digital Panel’ display type from the signal display and thus by selecting the ‘Speed’ option in the ‘Display Type’ drop down list an RPM will be available.3496class="post-3496 post type-post status-publish format-standard hentry category-p8000 tag-data-acquisition tag-distortion tag-earth tag-ground tag-noise tag-p8000"
The ground connection should be used if an issue has been observed in measured data, such as significant electricity supply (50Hz or 60Hz) distortion or significant noise.
It must be attached it to a very good earth point (like a steel pipe or foundation)
It should be noted that sometimes connecting the ground cable to earth can actually make matters worse. It depends on the situation.3412class="post-3412 post type-post status-publish format-standard hentry category-dats category-news tag-dats tag-p8000 tag-software tag-windows tag-windows-7 tag-windows-8 tag-windows-xp"
Microsoft has recently announced that security updates and patches for its Windows XP operating system will end from 08 April 2014.
Many organisations are now having to update older PCs and laptops to Windows 7 or Windows 8. Continue reading The end for Windows XP.

Case Study: What can I do if the transducer I am using has a non-linear sensitivity over its measuring range?
Recently a PROSIG user wanted to measure a specific temperature parameter on a running engine. The transducer being used was one of the engine sensors built into the engine operating system to minimize engine emissions and maximize fuel economy. Unfortunately, the sensitivity of this transducer was not constant over the desired temperature range. The question then became, how can the output from this non-linear transducer be used to accurately measure the desired temperature parameter?
