Max/Min Mode - Ambient Weather WS-2801A User Manual

or actual temperature is 60.0 °F.
The uncalibrated or measured temperature is 58.7 °F.
Offset = Calibrated Temperature – Uncalibrated
Temperature = 60.0 – 58.7 = 1.3 °F.
Enter the temperature offset +1.3 °F.
Example 2:
The calibrated absolute pressure from a calibrated
pressure sensor, or actual absolute pressure is 28.61
inHg.
The uncalibrated or measured absolute pressure
measured by the weather station is 28.66 inHg.
Offset = 28.66 – 28.61 = -0.05 inHg
Enter the absolute pressure offset -0.05 inHg
Note: The absolute pressure offset will also affect
the relative pressure. To adjust the relative pressure, only
(independent of the absolute pressure), reference Section
4.1.
Normally, you would not calibrate the absolute pressure
because it is difficult to obtain a calibrated source. The
preferred method is to calculate relative pressure to an
official source near you, as described in Section 4.2.2.
To exit the calibration mode at any time, press the
LIGHT/SNOOZE button.
