2 Operating Instruction

2.1 Chassis pan


2.2 Basic operation

2.2.1 Display interface


1、Select the type of injector:


2、Current Injector conditions:


3、the injector count method:

T: according to the number of counts;

4、injector counting time:

T :0-2000 times

5、injection signs: icon display indicates the beginning of the injector fuel injection;   6、pulse width: 100 ~ 3000uS;

7、injection frequency: 1 ~ 30Hz

8、the count flag: Icon display indicates the injector start counting;

2.2.2 、Key Features   ON/OFF button:

On / Off Injector;   COUNTE button:

Start / stop counting.

When the number is 0, the injector has been working, do not stop; MODE button:

A, short press MODE button to switch to a different injector conditions;


B., long press the MODE button to switch between test patterns and resistance injector test mode;(Valid only in the injection stopped)

C,After entering the resistance test mode, connect the injector first, and press the ON/OFF button once. After 2 seconds, the resistance of the injector will be displayed on the screen. The unit is milliohm.

If it is found that the measured resistance deviates greatly from the actual resistance, it should be calibrated.

Calibration method: In the resistance measurement interface, directly short-circuit the two clips of the injector, and then short-press the “Counte” key. A “#” symbol will appear at the upper right of the screen. After this symbol disappears, calibration is completed.

Screen listing shows 0 mohm. ADJ knob:

Consists of two parts function   A. Common parameter settings

The first step,   Short press down to select the setting of the project, there is a corresponding position cursor display, divided into: Injector brand choice / count value / width / frequency, cycle through the four setting items, the current cursor location for the selected projects;

The second step,Rotate Left or Rotate Right, modify the current value of the item.
