PAYLOAD METER II RE-INITIALIZATION PROCEDURE
This procedure is designed to reset the Payload Meter II to clear repeated F.CAL errors.
This procedure is necessary to fix a rare condition in
the operation of the meter. Indication for this procedure
is a repeated display of
F.CAL
on the meter despite
repeated calibration. If possible, download the Pay-
load Meter before performing this procedure. This
procedure will erase all memory and user settings.
NOTE:
This procedure should be performed before any
Payload Meter is returned for warranty or repair.

engine inputs into the payload meter can be manipu-
lated to indicate engine running and engine stopped.
