Temperature/Humidity Sensors - Omega WMS-16 User Manual

To set barometric pressure offset, for sea level, you must first
obtain a reliable barometric pressure for your location. The
barometric pressure range is 28.25 to 30.75. This can be found
by contacting the nearest airport or weather service facility.
Nominal barometric pressure is 29.6 inches of mercury.
Call up the main screen (Figure 4) on the display terminal by
pressing "Esc" for main menu. Press "2" for Current
Observations at the main menu. Then press "1" for
observation display (Figure 4).

Temperature/Humidity Sensors

Wire the cable from the Temperature/Humidity sensor into the
terminal strip on the WMS-16 module as shown in Figure 1.
Call up the main screen (Figure 3) on the display terminal by
pressing "Esc" for main menu. Press "2" for Current
Observations at the main menu. Then press "1" for
observation display (Figure 4).
Obtain current values for temperature and humidity from the
nearest airport or weather service facility, and see that the
values shown on the main display agree approximately with
them.

While watching the main screen, slowly turn the offset
adjustment screw. Clockwise will decrease the pressure
reading. You may have to turn the adjustment 3 to 10
revolutions before the display starts to change. Turn the pot
slowly in single turn increments, then wait for the screen to
update, every five seconds. If the value is moving away from
the correct value obtained above, turn the screw in the
opposite direction. Continue turning the screw
until the displayed value agrees with the value
obtained from the airport or weather service.

To simulate a change in temperature and humidity, lean close
to the sensor (or to the solar shield) and breathe onto the
sensor until you see a corresponding increase in the displayed
temperature and humidity values.
