To Next PageTo Next PageWhat to do if the J.P. Instruments GPS display freezes or is incorrect?
If the J.P. Instruments GPS display freezes or shows incorrect information, it might be due to a power transient causing a processor malfunction. To resolve this, recycle the power to the EDM.
How to fix off-scale EGT columns (too high or low) on J.P. Instruments GPS?
Off-scale EGT column readings on your J.P. Instruments GPS might occur if the EDM is in Normalize view (blue EGT scales). Return to Standard mode by holding the LF button.
What to do if peak is not found during LeanFind on J.P. Instruments GPS?
If the peak is not found during LeanFind on your J.P. Instruments GPS, ensure Lean Find is activated and that you are not stopping while leaning. Lean at a speed of approximately 10°F per second.
Why does LeanFind find a peak too soon on my J.P. Instruments GPS?
LeanFind might find a peak too soon on your J.P. Instruments GPS due to failure to pre-lean before performing LeanFind, stopping while leaning, or leaning too slowly. Continue to lean without stopping, and lean more rapidly.
What to do if there is a missing column in the J.P. Instruments GPS display during flight?
If a column is missing from the J.P. Instruments GPS display during flight, it could be due to a reading that is jumping around or incorrect because the probe is removed from the line up. Replace the EGT or CHT probe shown in the error message on the next flight.
How to fix a missing column in the J.P. Instruments GPS display upon start up?
A missing column in the J.P. Instruments GPS display upon startup indicates that the diagnostic routine has found an open line or probe with no connection. Replace the EGT or CHT probe shown in the error message.
