5Please visit www.nkhome.com/kestrel/DROP for more information.

Connecting to an iOS Device

• Please see: www.nkhome.com/pdfs/Kestrel_Connect_Instructions.pdf

• All data logged by the DROP since your last connection will automatically download to your iOS

device upon your next connection.

Bluetooth range

(Up to 100 feet)*

Press button to connect BT quicker

(Also to test battery, LED will light Green)

Metal enclosures will block signal

* Bluetooth radio will perform better

if the DROP is elevated above

ground level.

MUST BE IN RANGE TO:

• Upload DROP Data

• Update DROP Settings

• View Real-time Data

• Receive Alerts

Water or ice may

affect range

6Please visit www.nkhome.com/kestrel/DROP for more information.

Getting Data Logs O iOS Device

There are two ways to export data off your iOS device:

• Directly from the Stats Page or

• Manage Logging from the Manage Page

You would then export to a valid email address or

using AirDrop.

Battery Replacement

(Please note: After battery replacement, you MUST reconnect to the Kestrel Connect application to ensure

time and date are updated for logging purposes.)

Temperature

• Aslightairowof2mphormorewillspeeduptemperatureresponsetimes.

• DROP can be used to measure water or snow temperature by submerging the thermistor.

Humidity

• For accurate humidity readings, allow the DROP to equilibrate to its environment. Depending on the temperature and humidity

differentialbetweenenvironments,thiscantakebetween20and90minutes.

• After submersion in a liquid, humidity readings, if available on your DROP, will be impacted until the humidity sensor area has fully

dried. Gently blowing on the sensor area (the small grid of holes in the front case) can speed this process.

• Afterexposuretotemperaturesover80°C,anoffsetinhumiditymaybepresentforaperiod.

Connectivity

• Typicalrangeis100ftbutlongerrangescanbeachieved.Metalenclosures,ice,submersioninliquids,obstructedlines-of-siteand

ground level or non-vertical logging positions will reduce connection range.

• If more than 3-4 DROPs are present, turning off auto connect and manually connecting one at a time will help the app connect

successfully. Typically, a maximum of 8 DROPs can be connected to a device at a time.

• The DROP uses Bluetooth Low Energy (BLE) to connect to iOS devices. Android compatibility is coming soon.

Operating Temperature

• TheDROPwilloperatewithoutrestrictionfrom14°F/-10°Cto131°F/55°C.Operationatlowertemperatureswillbelimitedbythe

availablepowerandlifespanofthecoincellbattery.Downloadingafulldatalogintemperaturesbelow14°F/-10°Cmaytaxthe

batterytothepointwheretheDROPwillnotoperateuntilthebatteryhasbeenreplaced.Forbestresultsbelow14°F/-10°C,usea

freshbattery,keepdatalogdownloadsshort(1000datapointsorfewer),orallowtheDROPtowarmtoabove14°F/-10°Cbefore

connectingorattemptingtodownloadlogs.TheDROPcangenerallybeexpectedtocontinuetologdatapointsdownto0°F/-18°C

with these limitations.

Battery Life

• Coldconditions,frequentloggingrates,andfrequentlogdownloadswillallshortenbatterylife.

• Whendownloadingextremelylargedatalogsormakingrmwareupdates,avoidusinglowbatteriesandconditionsbelow32°F/0°C.

• EstimatedbatterylifeatthebaselinesettingsprogrammedintoyourDROPwhenshippedfromthefactory(10minloggingrate,5

secconnectionrate)androomtemperature(77°F/25°C)isabout4months.Intensiveloggingandconnectionsettings(2seclogging

rate, constant connection) can reduce battery life to as little as 11 days.

Temperature (Air/Water/Snow): Air temperature is

the ambient temperature of the air and water vapor as

measured by a thermometer or other measuring device

in which the thermal element is dry and shielded from

radiation. Water and snow temperature are measured with

a measuring device in direct contact with the environment.

Available units are Fahrenheit – a temperature scale where

wateratsealevelhasafreezingpointof+32°F°,anda

boilingpointof+212°F;andCelsius–atemperaturescale

wherewateratsealevelhasafreezingpointof0°Canda

boilingpointof+100°C.

Relative Humidity: The ratio of the amount of water

vaporintheairataspecictemperaturetothemaximum

amount that the air could hold at that temperature,

expressed as a percentage. Relative humidity is a function

of temperature and therefore changes as the temperature

changes, even if the amount of moisture in the air remains

constant.

Heat Stress Index: A measurement of the air

temperature in relation to the relative humidity, used as

an indicator of the perceived temperature.

Dewpoint: The temperature at which the water vapor in

the atmosphere begins to condense. Any further cooling

causes condensation (fog and dew). This is also the

temperature of saturation at which the dry-bulb, wet-bulb

and dew-point temperatures are all the same.

Wet Bulb: The lowest temperature in the ambient

atmosphere yielded by evaporating water from a wet

muslin-covered bulb of a thermometer.

Glossary of Measurements

Absolute/Station Pressure: The actual measured pressure

of the weight of air above the measurement point. Often

called station pressure.

Density Altitude: TheequivalentaltitudeintheICAO 

standard reference atmosphere for the measured temperature,

relative humidity and air pressure. A measure used primarily by

pilots, high-performance engine mechanics and long-range

shooters.
