Barometric pressure is pressure adjusted to sea level. You need reference altitude to calculate this number. This is used to equate pressures independent of the altitude in order to view pressure changes/storm fronts. This calculation is typically used in meteorology.

... Read more

Station pressure is used in practical applications outside of weather. For example, ballistics, air flight, and drag racing. This is the unadjusted atmospheric pressure felt at your current location.

Our article Understanding Pressure, Altitude and Density Altitude talks about Altitude and Barometric Pressure in great detail. The article also describes how to utilize your Kestrel to take these measurements.

The Stats page shows the data that is currently stored in the logger on the DROP. Currently you need to disconnect and reconnect to acquire more data, so the Refresh is useful only during an active download. You can hit the Refresh button to populate more Stats as they are in the process of being downloaded to the application.

You must disconnect and then reconnect the DROP to get any additional logged data uploaded into the program. You can do this by closing and re-opening the program as long as Device Power Saving is turned ON.

Set the logging rate to the max, 12 hours. You could set the data refresh rate to its max, 1 minute, but that will only have an effect when connected to the DROP. Also if you connect to the DROP in colder weather, this will affect battery life more than in warmer temperatures. If possible, warm up the DROP before doing a data upload to Kestrel LiNK to help with battery life.

This is really just personal preference. If the DROP name is related to its location or purpose, then obviously changing the name would be helpful each time.

Yes. Once you make the settings to the DROP (custom name, logging rate, data refresh rate), those settings stay with the DROP itself. This means that all anyone else would have to do is download the Kestrel LiNK(Formerly Kestrel Connect) app from the iTunes App store and connect to the DROP to access.

To read the data that has been logging on the DROPs, all you have to do is simply connect to the DROP with your iOS device and the data log will be downloaded. You can tell it’s downloading by looking at the DROP’s name near the top of the screen, as you’ll see a spinning graphic and a percentage that changes over time. Once it has reached 100%, you’ll have to navigate to the Stats screen using the menu at the bottom of the app. There you’ll find an Export Data button at the top which you can use to email the data log to yourself and then print it out.

Try the following:

  1. Make sure you have an device that is compatible with Kestrel LiNK. Compatible devices include: iPhones- iOS 6 installed; iPhone 4s or later. iPad: 3rd generation or later. Android 4.3 and higher. Works with most Android devices with Bluetooth Smart®, including Samsung Galaxy, Nexus 4, Motorola Droid and other recent generation phones and tablets.
  2. Make sure Bluetooth is ON on your device.
  3. Make sure the battery tab has been pulled and power is on the DROP. It may be necessary to replace the battery if the light doesn't come on when you press the black button on the front of the DROP.
  4. If the battery tab is pulled out, try taking the battery itself out of the DROP and reinserting. Also, make sure there isn't any metal or obstructing objects between the DROP and your device.

If none of these steps work, contact our technical support team at techsupport@nkhome.com. <... Read more

There is no barometric pressure reading on the DROP D3. Currently only station pressure is provided. Station pressure is the pressure felt at the current location without adjusting for altitude. Station pressure is used in applications like ballistics and auto racing. Typically barometric pressure is only used for weather related phenomenon. Barometric pressure may be added in a future release.

A data point is a collection of all the measurements at a set point in time. In other words, if you record the temperature, humidity and pressure at 12:00 AM, all these numbers will constitute a single data point. Thinking of a data point as a “data set” may help.

This is dependent on a setting for the DROP in the Manage Data Log section. If you go to Manage->Manage Data Log, you will notice a Wrap Log toggle button. If the Wrap Log toggle button is slid to the right (indicates ON), then the oldest logged data will be overwritten when the data logger is full. If the slide is to the left (indicates OFF), then no more data will be collected when the data logger becomes full.
