COMMON ERRORS

1.  Slow sensor drift reading.

A sensor reading that slowly rises or falls 

(positive or negative) from the set zero 

value.

2. Fast sensor drift/invalid reading.

A sensor reading that quickly or rises or 

falls (positive or negative) from the set zero 

value, possibly so much that the reading 

becomes invalid.

3. No sensor to eDART/CoPilot 

communication.

The sensor reading cannot be obtained by 

the eDART or CoPilot.
