 Fluke 98 Automotive Scopemeter
Your new 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

Record Capabilities
Plot Readings
Plots up to 4 readings over time simultaneously.

Min Max Trendplot
Logs minimum, maximum, and average readings to memory at full accuracy and displays all three as graphs. Uses automatic vertical scaling and horizontal time compression for hands-off recording from a minimum of 60 seconds to a maximum 32 days full screen. The horizontal time compression process records data until the screen is full. Then it selects the greater maximum and the lesser minimum between each pair of readings. These readings are then compressed to fill half the screen. The process then repeats itself until up to 32 days have passed.

Intermittent Record
Monitors and records signal continuously for a full 128 screens (single channel) or 64 screens (dual channel) of data. Intermittent recording is initiated on entry and is terminated at any time by pressing any key on the instrument (except ON/OFF).Time base ranges 20 ms per division and slower (> 20 ms/division).

Flight Record
Records up to 40 successive screen snapshots in memory. Preserves the last 40 screens in an endless loop fashion. Time base ranges 200 ms per division and faster (< 200 ms/division).
