TABLE 4-2
Cp-Ls ACCURACY BETWEEN
0.4 AND 4 ON THE CGRL DIAL.
Points to remember in measurements above 20
kHz are:
1. The Cp
-
L, bridges are more accurate than
the C,
-
L bridges.
2. Rccuracy is greater with the CGRL dial a t a
low setting, s a y between 0.4 and 4.
3.
While the basic 1% bridge accuracy may be
plus or minus, the error introduced above 20 kHz is
always minus.
For greater accuracy between 50 and
100 kHz, add 1% t o the indicated value.
4. When measuring D or Q above 20 kHz, always
use the C p
-
L, bridges.
The above information is given merely a s a guide
for those wondering what accuracy they might reason-
ably expect at frequencies from 20 to 100 kHz.

Bridges are not tested a t these fre-
quencies, and thus operation above 20
kHz is not included in the specifications.
