5. Operating Instructions
The DANOPLUS KIB0381 offers four distinct pulse modes to diagnose various injector conditions.
5.1 Mode Selection
Press the MODE SET button to cycle through the available pulse modes. The digital display will indicate the currently selected mode (1, 2, 3, or 4).
- Mode 1: Single Pulse Mode
When the PULSE key is pressed, the instrument will send out a single pulse with a pulse width of approximately 255 milliseconds (Ms).
- Mode 2: Short Pulse Mode
When the PULSE key is pressed, the instrument will send out 50 pulses with a pulse width of approximately 7 Ms each.
- Mode 3: Long Pulse Mode
When the PULSE key is pressed, the instrument will send out 100 pulses with a pulse width of approximately 3.5 Ms each.
- Mode 4: Continuous Pulse Mode
In this mode, the instrument will continuously output pulses at a rate of about 50 pulses per 1450 Ms, with a pulse width of approximately 7 Ms each. This mode continues until the PULSE key is pressed again to stop.
5.2 Performing a Test
- Ensure the tester is correctly connected to the vehicle battery and the fuel injector as described in Section 4.
- Select the desired pulse mode using the MODE SET button.
- Press the PULSE button to initiate the test. Observe the injector's operation.
- For continuous mode (Mode 4), press PULSE again to stop the test.
- Press the RESET button to clear the current test state if needed.
Note: This tool is designed to test the electrical functionality of the injector. For comprehensive diagnosis of fuel flow and spray patterns, it is recommended to use this tester in conjunction with a fuel pressure tester and appropriate collection equipment (not included).
