Problems of Existing Auto Circuit Testers

Digital LCD Automotive Circuit Tester:

Cheap ($21)but only by detecting the voltage to determine whether the vehicle electrical circuit is a short circuit or a broken circuit. Very low efficiency and cannot detect component problems.

KM10 Power Circuit Probe Kit:

Cheap ($79) and it can test for continuity, diagnose circuit failures, check the good and bad ground, activate some components on and off the vehicle, capture MIN/MAX voltage, etc. But you need to buy an additional oscilloscope if you need to check and confirm the fault caused by the car circuit sensor, for example: M.A.P. sensor circuit fault. And the KM10 mainly relies on the fuse to prevent overload or short circuit, so it is easy to damage. If you need to use it often, we do not recommend. By the way, it only support English language.

PPTM01AS:

DC Voltmeter: capable of applying battery supplied voltage or ground. AC voltmeter: TRMS, Peak-to-Peak/MIN/MAX, Frequency, Duty Cycle. Trace mode offers scope-like functionality. Resistance testing with a live or unloaded circuit. Fuel-injector test mode. Driver test for testing Module drivers. Self-resetting circuit-breaker. With oscilloscope function, circuit breaker and fuse double protection. But it is too expensive ($305) and complicated to use for inexperienced people. And it also only has English version

A Little More About SigmaProbe That We Think You'll Love

Sigmaprobe Smart test

Smart Test

Judge the VDC/OHM/AMP test intelligently

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.

Sigmaprobe Multimeter

Multimeter Mode

VDC/OHM/DIO/AMP/HZ mode test

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.

Multimeter Mode
Sigmaprobe Oscilloscope

Oscilloscope Mode

50KHz,800KSa/s

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.

Sigmaprobe relay test

Relay Test

Quickly test the relay status 

It shows 2 types of common automotive relay diagrams on the screen (5-terminal relay and 4-terminal relay). 

Connecting the relay test line to the relay terminal can quickly detect whether the relay is normal.

Relay Test
Sigmaprobe Injector Test

Injector Test

4 pulse signal choices for testing the injector status 

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.

Sigmaprobe positive/negative test

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.

Positive / Negative Test
Component Activation

Component Activation

Generate activation signal to the tested part 

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)

Sigmaprobe power supply

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.
