Before Calibrate the Altimeter

- The altimeter's calibration procedure design for use in the normal altimeter mode.

- As the al t i tude is calculated from the air pressure, the change of air pressure would affect the altitude reading.

- To achieve a more accurate reading, the SensorMaster II need to be calibrated from time to time as pressure may change gradually even within hours.

- Calibrate the SensorMaster II at which with a known altitude, such as at sea level or beside an altitude sign pole, because that altitude value has to be input the SensorMaster during the calibration procedure.

IMPORTANT: Input a incorrect altitude in the calibration procedure, it results a mistaken altitude reading in future.

Altitude Calibration Procedures

- Press and hold the [adjust] button for 2 seconds to enter the Altitude Calibration Display.

- Press the [adjust] button once again to enter the calibration sequence, the digits of the middle row of the display and the altitude unit will start flashing.

- Press the [start/stop] button to increase the number; press the [lap/reset] button to decrease the number. Hold down the button changes the number at a higher speed.

- After you set the altitude, press the [mode] button to exit the setting sequence.
