SM-28 SKYMASTER Manual V 4.05 - English
Getting Started
Your Skymaster package contains one 400-Hr Lithium CR2032 battery, a lanyard, and voltage
input numbers for humidity calibration. It is very important that you keep the calibration
numbers for future calibration needs. Each instrument has unique voltage input numbers. To
install the lanyard, feed one end through the hole at the bottom of the handle and tie it to the
other end. Open case and click into fully opened position or, if using a tripod, click to the 90-
degree 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 button on
the left. Use the MODE button on 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, while holding,
press the MODE button to change the units
of measure.
