Fluke 98 Series II Automotive Dual Channel Scopemeter

Fluke 98 Series II Automotive Scopemeter

The Fluke Automotive ScopeMeter® test tool is a powerful instrument with a wide variety of capabilities.

• Its menu-driven interface has automatic configurations for most of your tests, so you will find that the test tool is easy to use.
• Continuous AUTO RANGE, an exclusive Fluke feature, constantly acquires and displays the best possible signal.
• The secondary ignition pickup and automated ignition functions make it easy for you to analyze an ignition system malfunction.
• The Relative Compression mode helps you quickly find a low compression cylinder.
• The Secondary Ignition Single function displays the waveform along with the spark voltage, RPM, burn time and burn voltage.

Many problems you will encounter are under a load - on a road test.

• The Intermittent Record function can find and display such a problem. This record function can record up to 1280 divisions of continuous information.
• The Flight Record function records screen snapshots from 200ms per division up to full time base speed.
• The Plot Readings function allows you to plot up to four different readings of a signal over time with a single connection.
• Min/Max Trendplot continuously monitors the minimum, maximum, and average value of a signal's readings with time stamp.

Even though your instrument has been designed to configure itself to almost any test, review the following chapters to find out how easy test and measurement can be.
