This digital tire pressure gauge is designed for pneumatic and air pressure measurement, suitable for tires on trucks, bikes, and cars. It features an LCD display, automatic pressure identification, and multiple unit switching capabilities.
Product Overview
The device consists of a digital display, a rubber protective sleeve, and a copper joint for connection. It is powered by two AAA batteries.
Operation
- Power On: Press the ON button (left) to activate the device.
- Automatic Operation: When air pressure enters the gauge, the device automatically identifies the pressure without manual operation.
- Unit Switching: Press the FUNC button (right) to cycle through the available measurement units.
Battery Installation
The device requires 2 AAA batteries (not included). To install or replace batteries, open the battery compartment cover located on the back of the unit. Ensure correct polarity alignment. The LCD battery symbol will flash when the battery voltage drops below 2.5V, indicating that replacement is necessary.
