How to Use:
1. Start the engine and run to the normal working temperature. After the engine stops running, unload all spark plugs;
2. Make the throttle fully opened and press the connection of the pressure gauge on the spark cold hole;
3. Motors drive the engine to rotate at 100-150R/MIN speeds for 3-5 seconds. At this point, the pointer on the instrument will gradually rise, but will stop at a certain value. At this time, the indicator value is the compression pressure of the cylinder;
4. Press the button to zero the pointer;
5. According to the above steps, the measurement is repeated 2 to 3 times to improve the measurement accuracy.
