Use the double arrows icons to scroll one screen at a time. Pressing the pause/stop icon freezes the data recording so you can review it. This makes it easy to perform a road test or a wiggle test without having to watch the meter. The meter continuously records up to 262 screens of data for review. We can easily capture glitches and dropouts to detect wiring issues, failing components and intermittent problems. Here a constant voltage signal appears as a flat line, with no variation or glitches over time. Let’s select Volts DC to graph voltage change over time. Contact your Snap-on representative to learn more. This is especially useful for finding parasitic loads, faulty injectors, pumps and relays. Here are some optional probes available for specialized tests to detect glitches in pressure, vacuum and temperature in automotive applications.Ĭurrent measurements require the optional precision low amp probe. Most of these tests can be made with the standard leads included with the tool. You can select from over twenty graphing meter tests and display options, including Dual Graphing Meter, Volts DC, Volts AC, Frequency, Pulse width, Duty cycle and Dwell. Select Graphing Multimeter to measure or monitor a signal to see how its value changes over time. To get started, select the Scope Multimeter icon from the Home Screen. To avoid damaging the meter, never attempt to measure more than the meter’s rated capacity. The graphing multimeter and lab scope are powerful diagnostic tools that give you the ability to directly test vehicle components to verify faulty components before replacement. This module is designed to help you get the most out of your MODIS EDGE diagnostic tool, and covers the use of the graphing multimeter and lab scope.
