15.4 Calibration
15.4.1 Fuel Flow Calibration (Piston Fuel Flow Sensor Only)
The Floscan 201B-6 (201-030-000) fuel flow sensor ranges from 28,000 to 31,000 pulses/gallon.
The G900X/G950 default fuel flow setting is set to 29,500 pulses/gallon. This corresponds to a K factor
setting of 2,947 (29,500 x 0.0999 = 2,947). The Floscan fuel flow sensor comes with an actual K factor
number measured during unit calibration (see Figure 15-24).
NOTE
If the Floscan tag shown below is lost, the serial number of the Floscan sensor can be
supplied to Floscan to obtain the calibrated K factor value.
Figure 15-24. Example Fuel Flow Sensor
To adjust the G900X/G950 for the actual K factor of the fuel flow sensor received, perform the following
procedure:
1.
Pull the MFD and PFD (s) circuit breakers.
2.
While holding the ENT key on the MFD, restore power by closing the MFD circuit breaker.
3.
When the words
appear in the upper left corner of the MFD,
release the ENT key.
4.
Repeat steps 2 – 3 for the PFD(s).
5.
Using the PFD, go to the Fuel Tank Calibration page (see Figure 15-25).
