Tire pressure measurement steps

Step 1: Install batteries to the instrument and turn it on.

Step 2: Select the tire pressure measurement mode.

Step 3: Align the measuring port of the instrument with the tire valve and press the instrument tightly for about 2 seconds. During this process, ensure that the airtightness between the measuring port and the tire valve is good, and the sound of gas leakage cannot be heard.

Step 4: After the reading is stable, quickly remove the instrument from the tire valve and read the tire pressure value (the tire pressure value is only displayed for 15 seconds).
