Fluke 289 Offers The Fluke 289 Industrial Logging Multimeter is designed to solve complex problems in electronics, plant automation, power distribution, and electro-mechanical equipment; it is loaded with powerful features so you can solve problems faster and help minimize downtime. Let the 289 be your watchdog for systems or processes while you are off doing other jobs. The elusive electrical intermittent is one of the most difficult problems for anyone to troubleshoot. The difficulty lies primarily in the timing. Being able to look at the symptoms while the problem is present simplifies the troubleshooting process considerably. However, the old adage “A watched pot never boils” seems to be applicable to electrical intermittents as well. Being present, as well as being able to take an electrical measurement while the problem exists, are the two biggest challenges in tracking down an intermittent.

There are a number of test tools that can help make the intermittent troubleshooting process a little easier. These tools range from complex signal analyzers and storage oscilloscopes to handheld digital multimeters (DMM). Of course, you may not have these tools available or the location of the problem makes it difficult to bring a large analyzer to the problem site.

A DMM may be able to tell you a lot about an intermittent without having to go back to the shop and haul that storage scope to the job site. DMM features for hunting intermittents Couple the basic measurement features of a DMM (ac volts, dc volts and resistance) with some form of measurement recording ability, and you have a tool for detecting the symptoms of intermittents. Not too long ago, you could buy a voltage or current measuring tool that was built around a mechanical strip chart recorder. Just place the input on a voltage, or clamp a current transformer around a conductor and the recorder would make progressive marks on a strip of paper fed under the marking pen. The maximum length of the recording was determined by the amount of paper that could be placed on a roll of paper. This same strip chart recorder technique has been incorporated into some of today’s DMMs. Have a feature called MIN MAX AVG Recording Mode.

Just like the strip chart recorder, the DMM takes a reading of the input at regular intervals. But instead of saving each reading, it compares the reading to two previously stored values to determine if it is higher than previous highest reading or lower than the previous lowest reading.

If it is, the new reading replaces the old value stored in high or low reading register. After allowing the recording process to continue for a period of time, you can recall these registers to the display and see the highest and lowest reading taken during the recording time.

As an added bonus, these DMMs will also compute and store the average value of all readings taken during a given time period. TIP: Do not remove the test leads from the circuit being measured until you have either pressed the HOLD button to stop the recording, or looked at and documented all the stored values. Removing the leads while recording will result in the DMM processing the values present on the disconnected leads and affect the AVERAGE value and possibly the lowest or highest stored values taken during the time the leads were connected to the circuit. Multimeter safety by the numbers A common misconception in choosing a multimeter is that as long as you choose one with a high enough voltage rating, you’re covered.
