Tendency / Baro Display and Temp/Baro Display.
Pressure Tendency/ Baro Display
- In Barometer Mode, the pressure displays on the top
right corner of the display.
- The pressure tendency graph displays on the top left
corner of the display. The current time displays in the
bottom row of the display.
Pressure Tendency Graph
- The 1st column of the graph shows the relative pressure
of the last 6 to 9 hours.
- The 2nd column of the graph shows the relative pressure
of the last 3 to 6 hours.
- The 3rd column of the graph shows the relative pressure
of the last 3 hours.
- For expert users who intend to adjust the sensitive of the
pressure tendency, check the 'Pressure Tendency Value'
and 'How to set Pressure Tendency Value' for setting the
pressure threshold value.
Implications of the Pressure Tendency Graph
- In general, a rise trend in the Pressure Tendency Graph
forecasts a good weather ahead.
- A s t e a d y t r e n d i n t h e P r e s s u r e Te n d e n c y G r a p h
forecasts a steady weather ahead.
- A f a l l t r e n d i n t h e P r e s s u r e Te n d e n c y G r a p h
forecasts a bad weather ahead.
- Important: To get an accurate result, the user has to
stay at the same altitude for over 9 hours.

Why the Altimeter Need to be Calibrated
- As the absolute altitude is calculated from the air pressure,
the change of air pressure would affect the altitude reading.
- To achieve a more accurate reading, the WindMaster need to
be calibrated from time to time as pressure may change
gradually even within hours.
Before Calibrating the Altimeter
- Calibrate the altimeter at a place where the altitude is
determined, such as sea level (0 m) or beside an altitude
sign pole (e.g, 89 m), because that altitude will be inputted
into the WindMaster during the calibration procedure.
IMPORTANT: Input an incorrect altitude during the calibration
procedure, it results a mistaken altitude in future.
Calibration Procedures
- Press and hold the [adjust] button for 2 seconds to change
the display from Altimeter Mode to Altimeter Calibration
Display, the right most digit start flashing in the display.
- If the digit is flashing, it is selected. Press the [select]
button to increase the number.
- If the digit has been set, press the [start/stop] button to
select the next digit for adjustment.
- After you set the altitude, press the [adjust] button to exit the
calibration sequence.
NOTE: If the user intends to set the Altimeter back to absolute
altitude (altitude is calculated from the ambient air pressure)
after the calibration, press and hold the [adjust] button to
change the display to the calibration display, and then press the
[adjust] button once again to exit the display without changing
any number.

To Measure the Relative Altitude
- Th e W in dM a st er ca n m e as ur e r el at iv e a lt it ud e . F or
example, it can measure the ascending or descending
altitude between the starting point and the finish point of
a trail.
- To measure the ascending or descending altitude of a
trail by setting the altitude to 'zero' at a reference point
such as the starting point of the trail.
To Set the Altimeter to Zero
- Press and hold the [adjust] button for 2 seconds to change
the display from Altimeter Mode to Altimeter Calibration
Display.
- Press the [mode] button once to switch the altitude to
'zero' meter or 'zero' feet.
- Af ter t he Wi ndMa ster is s et to 'Ze ro', pre ss [a djust ]
button to exit the setting sequence.
- The Watch will display the relative altitude continuously,
he nce , t he u se r co ul d mo ni tor hi s/ her as ce ndi ng or
descending altitude by that number.
To Set the Altimeter back to Absolute Altitude
- If the user intends to set the Altimeter back to absolute
altitude (altitude is calculated from the ambient air pressure)
after a relative measurement, press and hold the [adjust]
button to change the display to the calibration display, and
then press the [adjust] button once again to exit the display
without changing any number.

time displays in the bottom row of the display.
IMPORTANT: If the user intends to get an accurate reading
of air temperature, the user must taken off the watch from

pressure tendency graph will become less sensitive to
the pressure change.
To Set the Pressure Tendency Value (PTV)
- Press and hold the [adjust] button to change the display
from Barometer Mode to Barometer Setting Display. The
right most digit wi ll start flashing. Press the [sel ect]
butt on to in creas e t he num be r. Pre ss the [sta rt /stop ]
button to select the next digit for adjustment when the
previous number has been set.
- After you set the value, press the [adjust] button to exit
the setting sequence. If n o any key operation in the
setting display for about 3 minute, the WindMaster will
return to the Barometer Mode automatically.
