Although calibration is optional and not required, the purpose of calibration is to fine tune or correct for any sensor error associated with the device's margin of error and inevitable sensor drift associated with electronic measurements. The measurement can be adjusted from the console to calibrate to a known source. Other features include min and max that resets daily or manually, barometric pressure trend arrow, and moon phase. Special notes and caveats - the backlight requires ac power to operate. The batteries are intended for back-up power only. The backlight will remain on for 5 seconds when on back up battery power only. The backlight will stay on if you use the ac adapter.
