Fluke - Event recording (or logging) with a Fluke 287/289 Digital Multimeter

Our thanks to Fluke Corp for allowing us to reprint the following article.


One of the major features of the Fluke 280 Series digital multimeters (DMM) with TrendCapture is their ability to record measurement data or "do logging". This application note explains what kind of logging these meters can perform, how to use the recording feature, and what information it can provide. This note also discusses how to use FlukeView® Forms PC software to increase the power of the Recording feature.


For the balance of this note, we will refer to the Fluke 289 DMM, although the information is equally applicable to the Fluke 287 DMM.


Differences between the Fluke 289 DMM and a data logger


The Fluke 289 does not do data logging in the traditional sense. Typically, the goal of a data logger is to sample the input signal at a rate sufficient to track activity that you might find in the signal. This often means that it is desirable to sample the input as fast as possible so you don't miss anything. The problem with this approach is you need a large storage place for the fast data sampling that is taking place. You can also end up wading through a lot of redundant data that is considered "normal" to find the exceptional data (or lack thereof)...
