h. Ref-urn the CONDUCTANCE control to zero on the G-scale.
i. If the C/L switch is at C, proceed to Step I, below„
if the C/L switch is at L,
set it to the C position„
j0 Set the meter switch to ZERO LEFT and zero balance the bridge as described in
paragraph 3.. 5.
k. Set the meter switch to ZERO CENTER,,
if necessary, adjust the C ZERO FINE
control for a midscale meter indication .
lo Connect the test inductor to the REMOTE STD coaxial connectors (or to the test
jig or test leads, if used).
m„ At the REMOTE TEST terminals, connect a reference inductor whose value and
accuracy are known.
n, Advance the CAPACITANCE control for an exact midscale indication on the
meter.
If the meter does not null at midscale, the value of the reference
inductor is greater than the value of the test inductor; interchange the two
inductors and readjust the CAPACITANCE control.
Oo Read the value on the CAPACITANCE dial and use the following equation
to convert the capacitance reading to an inductance differential value:
L = 25.33/C
where
L = inductance in mH
C= CAPACITANCE dial reading in pF
