How to use an Analogue Channel with Tachometer Signals on the P8000

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.

When should I use the ground connection on my P8000 data acquisition system?

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.

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?

How To Float Output Windows in DATS Acquisition V4

Nowadays it is easy to attach extra screens to most computers. It is not uncommon to have a two or even three monitor setups. Even with laptops it is fairly easy to attach either a full size extra monitor or maybe a small screen via USB. To make full use of this extra screen ‘real estate’ one needs software applications that allow parts of the interface to be moved into separate windows. This process is often known as ‘floating’. The following article outlines how to use floating tabs in DATS Acquisition. This feature has always been important in automotive testing, but is now becoming more useful in other applications.
