Welcome to Snap-on Training Solutions. This module is designed to help you get the most out of your ZEUS diagnostic tool, and covers basic digital multimeter functions.
The digital multimeter gives you the ability to quickly test and verify failed components before replacing them.
Select the Scope Multimeter icon from the Home Screen. Then select Digital Multimeter.
This multi-function meter can be used for a variety of automotive electrical measurements, like AC and DC voltage, DC current, resistance, and even diode continuity. To avoid damaging the meter, never attempt to measure more than the meter’s rated capacity.
Most digital multimeter tests are made using leads like these.
Current measurements require the optional precision low amp probe. This is especially useful for finding parasitic loads, faulty injectors, coils, solenoids, pumps, and relays. Contact your Snap-on representative to learn more about purchasing this option.
The digital multimeter displays a digital value. This type of display is typically used when the value being measured is not rapidly changing.
During normal operation, the meter continually measures the input signal. The stop button is used to stop or freeze the current measurement displayed.
The record button is use to resume operation. The record and playback controls are not used with the digital multimeter.
The meter also features tracking of the MIN and MAX measurements in the profile. Selecting the refresh icon clears these values and the tracking starts over.
Use the expand/collapse icon, to change display views to show profile controls.
Before performing a resistance or current measurement, calibrate the meter to insure accurate results.
To calibrate, select Yes. Follow the onscreen instructions to complete the calibration. Then select OK.
Once completed, zero ohms should be displayed when the leads are connected together.
When the leads are separated, the upward arrows indicate infinite resistance or an open circuit.
To learn more about Digital Multimeter settings refer to the ZEUS user manual.
