8. Use the tensiometer (upper cable thickness = 3/32 in, LH and RH fuselage cable thickness = 1/8 in) to measure roll cable tension at locations specified in, see Figure 90. Ensure they all are within 25-30 lb of tension. Refer to the manufacturers’ calibration card to correctly read cable tension for the cable diameter.
