Can the atmospheric data centers display imperial and metric measurements?

All data can de displayed in either imperial or metric measurements. Click reset button to choose measurement displayed when in the Wind, Temperature, Barometer, or Altitude display screens.

Why does the elevation begin to change after I set it, even though my ADC has stayed in the same place?

The altimeter function of the ADC Wind, Pro and Jetset uses the unit's barometer to determine elevation. Since the ADC is very sensitive to barometric pressure, if weather patterns are changing, resulting in a rising or falling barometer, the elevation readout will also change.

How often should I calibrate (set) the elevation to a known point of elevation?

We recommend calibrating your elevation at least daily when using your ADC as an altimeter. You can use known benchmarks or topographic map data to determine elevation.

How accurate is the altimeter once it is calibrated?

Once calibrated, it is accurate to +/- 3 meters (10 feet), unless weather changes occur since the last calibration.

How do I calibrate (set) the elevation?

1. Click mode button until the altitude display is showing.
2. Press and hold mode button for about two seconds until "Altitude Alarm On/Off" is displayed.
3. Click mode button once until you see "Altitude Adjust".
4. Hold reset button down for several seconds until the elevation offset number (top, large number) starts blinking.
5. Using either the set button (to go down) or the reset button to go up, change the offset number until the bottom, smaller number reads the elevation that you want it to. When you are done, either wait 15 seconds or press and hold the mode button until the display returns to the main altitude display.

Why does the barometer on my ADC (Summit/Pro/Jetset) not read the same as my local weather station?

Your ADC reads true barometric pressure, not barometric pressure relative to sea level. If you happen to live very close to sea level you will notice that there is little, if any difference between the barometric pressure reported locally and the reading on your ADC. The higher you are in altitude, the more difference you will see between the true barometric pressure on your ADC and pressure relative to sea level as reported locally. Also, keep in mind that even after adjusting for pressure relative to sea level, there may be significant weather pattern differences between your location and the location of the nearest reporting weather station.

Can I convert true barometric pressure to pressure relative to sea level?

You can, with a calculator. If you multiply .0011250926 by your elevation in feet you will get the offset number for barometric pressure in inches of mercury (InHG). Add that number to the inHg reading of your ADC and you will have barometric pressure relative to sea level.

How can I tell if my barometric pressure is rising or falling?

The ADC Summit, Pro and Jetset have a 24-hour bar graph that gives a graphic and numeric history of barometric pressure over the last 24 hours. Click the mode button until you get to the barometer screen and then click the set button once and the bar graph will display. You can also display the numeric readings for each hour going back 24 hours by clicking on the set button repeatedly.

My ADC seems slow to react to temperature changes. Is this normal?

Yes. As with liquid filled thermometers, digital thermometers do not react instantly, but may take a few minutes to adjust. For accurate temperature readings, do not hold the ADC in your hand or next to your body. Your body temperature will alter the temperature readout.

Can I calibrate the temperature sensors on my ADC?

Yes. While accurate from the factory, some temperature sensors may require calibration over time. You can easily adjust the readout +/- 9 degrees Fahrenheit in 1/10th degree increments.

Why does my LCD display dissapear when I turn on my backlight?

This is a good sign that your battery is dying. You should change the battery and if the problem persists contact our warranty department.

How do I calibrate the temperature sensors?

1. Click mode button until the temperature display is showing.
2. Press and hold mode button for about two seconds until "W.Chill Alarm On/Off" is displayed.
3. Click mode button once until you see "Temp Offset".
4. Hold reset button down for several seconds until the temperature offset number (top number) starts blinking.
5. Using either the set button (to go down) or the reset button to go up, change the offset number until the temperature readout on the bottom left reads the temperature that you want it to. When you are done, either wait 15 seconds or press and hold the mode button until the display returns to the main altitude display.

What kind of battery does the ADC's take?

The ADC's take one CR2032 Lithium battery. These are very commona and can be found at most general stores where batteries are sold.

How do I turn my ADC off?

Just like a watch, the ADC units do not turn off. The battery will last about a year with normal use.

Is my ADC IR software compatible with Windows Vista?

It is, you will have to visit our Downloads page to download the proper Windows Vista Driver for the ADC IR.

The link to the Software on the instruction cd doesn't work. How can I install the softare for my ADC IR?

You can access the files manually. With the CD inserted, open "MY COMPUTER" in your start menu. Right click on your cd drive lavbeld "Brunton ADC." When that menu opens up select "Open." When that window opens double click the "Manual" folder. Next, you will select the Folder labeled "adc_ir" and inside that folder you will find the Softare and the driver programs needed to be installed.

Is the ADC Ridge available in Meters?

The ADC Ridge is not offered in meters, only in Feet.
