SigmaProbe Covers 90% Automotive Circuit Testing Scenarios.
Smart Test
One click to identifies voltage, resistance, positive/negative
SigmaProbe™ recognizes the measured signal and displays values of VDC, OHM, AMP, P/N automatically in one mode.
No need to switch between different test modes.
Multimeter Mode
No multimeter is needed to test DIO\HZ\Duty Cycle
SigmaProbe™ support voltage, diode, current, resistance, & frequency test.Testing the condition of the wiring or components of an automotive circuit system through continuity testing
Oscilloscope Mode
Help you sampling & analysis the electrical signals efficiently
Maximum 50KHz bandwidth, 800KSa/s sampling rate.
The SigmaProbe™ sampling time interval setting is available. which is used to measure AC voltages and can be used on any AC voltage or pulse waveform signal.
SigmaProbe™ can be used for tests such as checking diode ripple in alternators, ABS sensors, crankshaft sensors, etc.
Relay Test
Even newbies can get you up and running quickly
SigmaProbe™ offer 2 types of common automotive relay (5-terminal relay and 4-terminal relay) connection guide diagrams.
Easy to diagnose the relay condition. No worry mistake connection burned the component.
Injector Test
4 Pulse signal test, know your injector status more accuately
The SigmaProbe™ 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.
Positive / Negative Test
Automatically judge the positive/negative poles and display on the screen
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.
Through the identification of the probe, the positive interface voltage or negative grounding icon will be displayed on the screen.
Component Activation
Test isolated components instantly by hooking up the SigmaProbe™ to the car battery
SigmaProbe™ has 3 activation modes:
MOMENT (moment activation)
LATCH (lock activation)
PULSE (pulse activation).
It's able to apply battery power or ground right to the probe tip gives you the ability to activate and dynamically test electrical components such as lights, motors, horns and other.
(Note: Can not be used for ECU, sensor module casually, there is a risk of burning)
0-5V Power Supply
Supports 0-5V voltage power supply, simulate the voltage output by the sensor to the ECU
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.
