The main test functions: voltage test, resistance test, positive/ negative test (display as VDC, OHM, AMP). It is mainly used for quick test without switching between different test modes.

Automatically recognize the measured signal and display values of voltage or OHMs.

Digital display intelligent multimeter meets all functions of vehicle multimeter (VDC, OHM, DIO, APM, HZ). It can continuously test circuits or components of vehicle circuit system.

Support sampling time interval setting.

Support voltage test range: 1V~49V.

“START/STOP" (press “OK" to start or stop waveform refresh).

“DIV" voltage per grid (test range 1V-49V), press "UP" and “DOWN" keys to adjust the voltage value.

It has 4 pulse signal modes, which can be connected to the injector by outputting different pulse signals to test the injector.

The Probe outputs different pulse signals to the injector and checks the spraying status of the injector. This function can help diagnose injector conditions. It can be used with any fuel pressure tester.

Use the Probe Tip to find the positive/negative wire of the power supply.

Through the identification of the probe, the positive interface voltage or negative grounding icon will be displayed on the screen.

SIGMAPROBE has 3 activation modes: MOMENT (moment activation), LATCH (lock activation), PULSE (pulse activation). 

The component activation function is used to generate activation signals to test components, such as activating lights, motors, horns and other on-board power supply equipment.

(Note: Can not be used for ECU, sensor module casually, there is a risk of burning)

Simulate the voltage output by the sensor to verify the wiring to the ECU. Sigmaprobe supports a power supply voltage of 0-5V. 

Note: 0-5V power supply mode designed as an active mode, but its function is different from the component activation mode. It can adjust the voltage output under 5V and limit the current to 100mA.
