1,When simulating signals like voltage, resistance, frequency, you can observe injection pulse width simultaneously.
2,You can examine the injection pulse width of an engine’s starting status.
3,By means of observing injection pulse width (ms), you can do these tests to the Electronic Fuel Injection engine:
Add rich mixture at cold starting;
Add rich mixture at running;
Add rich mixture at Idle;
Adjust AFS;
Feed back capability test of Oxygen signal under closed loop status;
Sever Fuel test;
MAP test; etc.
4,You can test the battery voltage of the engine’s stating status.
5,When observing signal’s frequency and pulse width, you can examine signal’s voltage and DUTY at the same time.
6,The blue LED can do the induce test of ignition high tension

SMART AUTO CIRCUIT TESTER

This is a smart tool for auto egineerer. It can be used to test the voltage, and check circuit continuity. Every technician should have one of this pen.

To test the voltage: Turn the switch to the VOLT, connect the clip to GND, the voltage value and waveform will be displayed on the screen, if the voltage value is larger than 0.5V, the blue LED lights on.

To test circuit continuity: Turn the switch to CIRC.If the clip is short to the test pen, the red LED lights on, the screen will display the message as shown in the left figure; Otherwise, if the clip is open to the test pen, the screen will display the message as shown in the left figure.

To power off the VoltPen: Turn the switch to OFF. Power off automatically after a few minutes, Before you can use it again, turn the switch to OFF first, then wait for 10 seconds.

Ignition Coil Tester

Function:

Fast, simple and accurate of way to determine the defects in the ignition coils.

Automatic distinguish different ignition coil type by auto switching control modes.

Adjustable Frequency control ranging from 120Hz ~ 12 KHz.

Safety and foolproof.

Applicable on coil-on-plug (COP), coil-near- plug (CNP), double ended coil-on-plug (DECOP) or wasted plug systems.

Simple operation:

Connect power from 12Volts car battery and the power LED will light up.

Insert the yellow banana plug to the yellow socket and connect the cable to the control terminal of the ignition coil.

Hook up the spark tester to the ignition coil.

Turn ON the frequency knob and adjust the frequency from low to high (clockwise).

Turn back to low frequency and observe the spark color which should be bluish purple.

Increase the frequency gradually and observe the spark line. It should be in a straight line when NORMAL. If the spark line is curved, it indicates that the coil is aging or there is an internal leakage.

Turn to maximum frequency until the coil is slightly warm, then turn down the frequency and observe the spark line whether it is continuous or intermittent. If arcing sound is heard but no spark indicates that there is internal leakage.
