SM-28 SKYMASTER Manual V 4.05 - English

Getting Star ted

Your Skymaster package contains one 400-Hr Lithium CR2032 battery, a lanyard, and voltage
input numbers for humidi ty cali bration. It is very important that you keep the calibration
numbers for future calibration needs. Each instrument has unique voltage input numbers. To
install the lanyar d, feed one end through the hole at the bottom of the handle an d tie it to the
other end. Open case and click into fully opened position or, if using a tripod, click to the 90­degree position. Your Skymaster’s sensors are extremely sensitive. Hold the Skymaster at
the bottom of the handle, away from your face and body, to avoid getting false readings. It is

also important that you do not touch the sensors.

Operating Modes:

Turn the unit on using the ON/OFF butto n on
the left. Use the MODE button o n the right
to scroll to the desired function. To turn off
the unit, press and hold the ON/OFF button
for 3 seconds, until the display is blank, then
release.

Changing the Units of Measure:

With the Skymaster on, change the units of
measure by selecting the mode you wish to
change (i.e. Wind speed). Next, press and
hold the ON/OFF button and, w hile ho ldi ng,
press the MODE button to change the units
of measure.

Bar Graph:

Units of Measure:

General Indicators

Modes

Wind Speed

Using the bar graph: The bar graph represents a 16­hour history of the barometric pressure. The column
labeled “0” indicates the current pressure. Each
horizontal bar represents +/-2 mb/hpa as indicated by
the pressure value indicator. (Please note that the bar

graph will not be displayed unti l barometric history has
accumulated, as the Skymaster only records bar ometric
pressure while the unit is on.)

Low Battery Indic ator:

Indicates the battery is running dry.

Data Screen:

Indicates the value of data being collected by the
Skymaster.

The Skymaster measures wind speed in six different
units of measure: Knots, Beaufort, Feet Per Minute,
Miles Per Hour, Meters Per Second, and Kilometers Per
Hour. To switch between units of measure please see
the Units of Measure section for instructions.

Current Wind speed:

In current wind speed mode, only the unit of measure
will be shown.

Maximum Wind speed:

Displays maximum speed recor ded since the unit was
turned on.

Average Wind speed:

Displays a running average over ten seconds.

Wind-Chill:

Displays the effect that air tem perature comb ined with
wind speed has on human skin.

General Relative Humidity:

Unit of Measure:

Temperature

Relative Humidity

Barometric Pressure

General Temper ature:

Displays the t emperature in Fa hrenheit or Celsius.

Heat Index:

Displays the measur e of how hu mid ity ac ts alo ng w it h
high temperatures to reduce the body's ability to cool
itself. In most cases, the heat index will be lower than
the temperature.

Dew point:

Displays the t emperature at which air becomes
saturated with moisture (the temperature at which fog
will form).

Displays the cu r rent relative humidity. Relative
humidity is the amount of water vapor measured in
the air, divided by the potential amount of vapor
that the air can hold – at that temperature. The
relative humidity comes factory calibrated.
However, the Skymaster can be calibrated manually
for more demanding field requirements. To calibrate
the relative humidity, see the Humidity Calibration
section.

The Skymaster can display barometric pressure in
inches of mercury (inHg) or in millibars / hectopascals
(hpa mb).

Barometer Indicator:

BAR - Indicates the unit is barometer mode.

Pressure History Bar Graph:

Displays barometric pressure history for the p a st 16
hours. Note: The unit must be on for 16 hours before
the complete graph is displayed. For more
information, please see section titled Bar Graph.

Altitude

Unit of Measure:

The Skymaster can display altitude in feet FT or meters M

General Altitud e Mode:

The Skymaster can register altitudes between -900 to
9000 feet.

Altitude Mode Icon:

ALT - Indicates the un it is in alti tud e mod e.

IMPORTANT INFORMATION: The SM-28 altimeter calculates alt itude based on changing air
pressure. Changes in the air pressure (caused by changes in altitude or weather patterns) will
cause the altitude reading to rise or fall. Your altitude should always be calibrated right before
use as an altimeter.

You should re-calibrate altitude if your ascent or descent takes more then a short period of
time. This will maintain instrument accuracy, since slight changes in pressure will cause the
altitude readings to cha ng e wh il e you rest at o ne location.

Remember that changing weather patterns will also affect your altitude readings. For example:
If the pressure changes .50 InHg, you will experience a change of altitud e o f +/- 470 feet, if
you are near sea level. Also note th at changes of altitude will change your barometric pressure
reading. For acc urate relative pressure readings while climbing or descending, you will need to
enter your altitude in calibration mode. Allow 15 minutes for the barometri c pressure readings
to respond to the newly calibrated alti tude.

Calibration

If you calibrate your altitude, you do not need to calibrate your barometer. It will calibrate
itself to the relative pressure after 15 minutes. However, you may wish to calibrate your unit
to a nearby reading obtained from a reliable weather source. Please remember that barom etric
pressure can change over a distance of just a few miles.

Barometric Pressure:

You may calibrate your unit in mb or inHg. Be sure to select your preferred mode prior to
calibration. While the unit is off, press and hold the on/off key for 2 seconds. The screen will
display current pressure with a flashing “BAR” indicator on the left side. When you see the
indicator flashing, release the on/off button. Press the on/off key to go up in units, press the
mode key to go down in units. After calibrating barometric pressure, wait 5 seconds and the
unit will automatically go into altitude calibra tion. If you do not wish to calibrate altitude,
simply leave the unit on and it will return to its norm al operating mode. The changes have
now been stored until you reca lib rate it.

Altitude: First obtain your local altitude.

Note: You may calibrate your altimeter in meters or feet. Be sure to select the mode prior to
calibration. With th e un it off, press and hold the on/off key for 2 seconds. You will see the
flashing “BAR” indicator on the left. After flashing for 5 seconds, it automatical ly moves to
Altitude calibration mode and you will see the current altitude and a flashing “ALT” indicator.
Press the on/off key to go up in units, press the mode key to go down in units. When you
have completed the calibration, the unit will automatically return to normal operation in a few
seconds. The changes have now been stored until you recalibrate it.

Humidity

NOTE: The relative humidity comes factory calibrated.

Figure A Figure B
First, locate the calibra t ion st ick er that was supplied with your Skymaster. It will have two

numbers displayed. You will ne ed to calibrate your unit to these numbers.

With the unit on, press and hold the o n/off button for 10 seconds. The display will turn off
and then back on, displaying the number 700 (Fig. A). Enter the first voltage input number
(in the above example, the number is 744) into this screen by pressing the mode button to
scroll up (omitting the decimal). Note: When in humidity calibration mode, the mode button
only scrolls up, not down, so it is important that you do not miss the number you are entering.
When finished, press the on/off button again, you will see the number 3000 (Fig. B). Enter
the second voltage input number (3056 in the example above), using the same procedure
as before. To store the changes, press the on/off button. The unit will then shut off with the
new values stored internally. NOTE: Each unit has unique voltage input numbers. It is crucial
that you do not lose your instrument’s numbers.

Impeller Replacement:
To replace the impelle r, use a sma ll scre wd riv e r to loos en the s et-s cr ew found on the back of
the weather monitor. Remove the impeller by twisting the impeller assembly clockwise (if you
are facing the back of the windmeter) to the “O” position marked on the rear of the meter.

Battery:

To replace the battery, turn the compartment cover in a count er-clockwise direction to remove
it. The battery will be visible in the battery comp artment. Insert a new CR2032 lithium
battery “+” side facing you. CR2032 batteries can be purchased anywhere b atteries are sold.
NOTE: Different modes have di fferent drains on the battery life. When left on in barometer
mode, the battery will last 400 hours. Wind speed &humidity will drain the battery quickest

Severe Weather Al a r m:
The severe weather alarm will sound if there is a dramatic change in pressure. The feature is
set to go off if the air pressure changes by 6 millibars (up or down) within a 3-hour pe riod.
(This is a good indication of sev er e weat her approaching.) The alarm will sound once for five
seconds. If the pressure continues to change by the same amount, the alarm will continue to
sound once every hour.
NOTE: the storm alarm feature is disabled when th e Skymaster is in Altitude mod e. This is to
prevent the alarm from sounding false alarms as your altitude changes (due to the altitude’s
effect on air density).
