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.
