Transfer capacitance standards calibrated
against NBS- certified reference standards.
Used to calibrate or check the accuracy of
3-terminal capacitance bridges and to
provide high-resolution comparison
measurements. Available in any value
from 0.01 to 1000-pF at 0.1% accuracy.
Designed for operation from 1 kHz to
1 MHz.
Extends the capacitance range of the
Model 75D to 0.1 pF, conductance range
to 1 mho, resistance range to 1 ohm, and
inductance range to 0.25 pH.
Divides Model 75D capacitance readings
by a fixed factor of 10 and permits
measurements down to O.OO0O1 pF.
Can be used with the Model 75D to perform
(if required) grounded (2-terminal)
measurements or tests. When installed on
the TEST binding posts, the adapter
provides a ground plane that enables the
(3-terminal) Model 75D to simulate
2-terminal (grounded) measurements or
tests.
Perforated metallic covers. Replace
cabinet when the Model 75D is rack¬
mounted.
