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.

Meter leads

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, 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 used to resume operation.

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 and show profile controls.

Meter Calibration

Before performing a resistance or current measurement, calibrate the meter to ensure accurate results. To calibrate…


Select Yes.


Then select Yes again.

0.0 Ohms

Follow the onscreen instructions to complete the calibration. 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 MODIS Edge user manual.
