 In calibration mode it starts counting pulses immediately. Calibration should be done over a measured half a mile. Press enter when starting the half mile, and again at the end. The number of pulses will be displayed on the screen. To write this to EEPROM and return to normal mode type 'RUN'. If the data is not suitable (missed marker etc) then just repeat the measurement.
