set at /4 to /2 turn from the tight position):
Maximum Capacitance: When set at the tight
position (tight defined as 28 oz-in/2.0 kg-cm), the
maximum capacitance will be no less than the
value indicated in the table.
Types 1, 5, 9
= ± (2.5% + 0.3 pF)
Types 2, 3, 4, 6, 7, 8 = ± (1.5% + 0.3 pF)
Capacitance drift with temperature (capacitor set

at /4 to /2 turn from the tight position):
Minimum Capacitance: When adjusting screw is
rotated 3 turns from tight position (2 turns for types
1, 5, and 9), the minimum capacitance will be no
greater than the value indicated in the table.
Types 1, 5, 9
Types 2, 3, 4, 6, 7, 8 = ± (1.5% + 0.5 pF)
