Calibration sequence

To calibrate the cassette
1. Ensure that the forks are dry, and the mode switch is set to "Wet On" with the
time delay set to 1 second
2. Check that the LED is flashing at a rate of one flash per second.
Proceed to step
3. Apply a magnet to the test point (as shown on
4. After a one-second delay, the LED will be continuously lit.
5. Within one second, rotate the mode switch two steps clockwise.
6. After a two-second delay, the LED will go out.
7. Within three seconds, rotate the mode switch two steps counter-clockwise.
Proceed to step 13.
8. Apply a magnet to the test point (as shown on
9. After a one-second delay, the LED will flash at a rate of one flash per second.
10.Within one second, rotate the mode switch two steps clockwise.
11.After a two-second delay, the LED will go out (stop flashing).
12.Within three seconds, rotate the mode switch two steps counter-clockwise.
13.After a two-second delay, the LED should flash twice per second.
14.If the LED is flashing twice per second, the calibration has occurred correctly.
Remove the magnet from the test point. After a one-second delay, the unit will return to normal
operation. Proceed to step 17.
15.If the LED is flashing once per second or it is continuously on, the calibration has failed. Remove the
magnet from the test point, wait ten seconds, and repeat from step 2.
16.If the LED stays off after the two-second delay of step 13, the sensor is not working correctly.
Check that the forks are clean and dry. Also, verify there is nothing jamming or touching the sensor. If
no fault is found with the sensor, the entire unit should be returned for repair
