Hi-Tec Digital Tire Gauge
1. Apply gauge to the valve stem. Press down evenly making sure it is correctly aligned so that air does not escape from the tire stem-within a few seconds the tire pressure will be displayed and the talking chip will clearly state the PSI reading.
2. Remove gauge from valve stem-gauge will hold the reading for approximately 7 seconds and then shut off automatically.
3. Pressing the 'recall' button repeats the last reading as many times as you wish.
4. Additional readings can be taken without having to wait for the display to go off.
