9.3 Calibration of Sensors Mode

In normal mode, press and hold the SET and ALARM keys at
the same time for five seconds to enter the pressure, wind gust,
rainfall and sunlight calibration mode. The letter "CAL" will
appear at the bottom of the screen.
Press the SET key to skip over a parameter to the next.
 Absolute Pressure Calibration
In the calibration mode, the "ABS" symbol will display at the
pressure section, the absolute pressure value will flash. (The
default value is 0.00 inHg)
Press the CHANNEL/+ key or MAX/MIN/- key to increase or
decrease the absolute pressure value (in increments of 0.01
inHg).
Press and hold the CHANNEL/+ or MAX/MIN/- key for three
seconds to increase or decrease rapidly.
Press the ALARM key to reset current value.
Example: The calibrated pressure sources measure 28.37
inHg. The display console pressure reads 28.75 inHg.
Offset = 28.37 - 28.75 = - 0.38 inHg
 Relative Pressure Calibration
In the calibration mode, press the SET key again, the "REL"
symbol will display at the pressure section, the relative
pressure value will flash. (The default value is 0.00 inHg)
