4. PRELIMINARY
Caution: Do not use unnecessary force to close a Test Set (T/S) valve. New units and
units returned to the manufacturer for servicing have been fitted with positive
stop spacers on all needle valves to permit the valve to firmly close without
damage. However, excessive force may overpower the knob set screw causing
valve damage.
To avoid incorrect results or damage to the aircraft or Test Set (T/S) instruments, the
manufacturer recommends that the user pay particular attention to the following preliminary
procedures. Each T/S is completely calibrated and tested before shipment. However, to
ensure the integrity of sensitive tests to be made, the pitot and static system pretests should
be done immediately before use. For user convenience, the T/S front panel decal also
details these referenced tests.
