As you press UNITS, the Energy EM cyclesbetween in, mm, and hPa.T YPICAL U NITS OF M EASUREEntering Barometric PressureBecause atmospheric pressure varies with both altitude and local weather con-ditions, you must enter the current barometric pressure for your location. Waitat least one hour after powering the Energy EM (to allow the circuit a chance tostabilize) before you enter barometric pressure. Once the barometric pressure isset, the Energy EM will calculate and display the correct barometric pressureuntil the unit is moved to a different altitude or power is interrupted.1. Determine the current barometric pressure.Many TV and radio weather reports carry this information. Or you may callyour local airport control tower.2. Press BAR to display current barometric pressure.3. Press and hold down ENTER until the barometric pressure reading stops flashing.At first, the entire barometric pressure reading will flash as a warning. Afterfour seconds the Energy EM will revert to normal entry mode (i.e., only onedigit flashing).4. Use ENTER to set the correct barometric pressure.See “Using the Enter Key” on page 15 for instructions on using ENTER.5. When finished setting the barometric pressure, press any function key to exit.The Energy EM saves the barometric pressure reading.AlarmsYou may set a special barometric pressure alarm which will alert you tochanges in the barometric pressure.
