TEST AND ADJUST FUEL QUANTITY INDICATOR USING PSD 60-1AF FUEL QUANTITY
SECTION D: CHECK GAUGE LINEARITY OR
ACCURACY AT ANY POINT OTHER THAN EMPTY
OR FULL QUANTITIES
Calibrate dial indication.
Complete Sections A and C.
Disconnect (P-1 or P-2) or "T" cable from
Subtract LOZ-HIZ capacitance measured in step
13 from capacitance given in Graph I or II for
desired dial reading.
Rotate SELECT switch to TU.
Set TU decade (D-1) 15-20 pf below desired
Adjust TU vernier (V-1) to read capacitance
calculated in step 4.
Rotate FUNCT switch to SIM TU ONLY.
Verify that indicator dial reads FUEL QUANTITY
IN LB given in Table 1.
Pull breakers. Restore aircraft to normal
Turn tester OFF. Store ground wire in lid.
