2. Press REC again. MAX will appear in the display. You will now see the maximum pressure and
the relative time at which it was recorded.
3. Press the REC key to see the MIN value along with the relative time.
4. Press REC to see the average value along with the relative time.
5. Press REC once again to continue the MAC/MIN/AVG measurements.
6. To finish the MAX/MIN/AVG setting, press and hold the REC key for 3 seconds.
5. To switch off the backlight, press the Backlight key. The backlight will stay on for 40 seconds.
6. The device will switch off automatically after 20 seconds to save battery life.
