APPLICATIONS
Applications for the Model 3200C include direct calibration of watt meters,
meter shunts, AC and DC current meters, I to E transducers, DVMs, DMMs and relay
coil current testing.
GENERAL DESCRIPTION
The Model 3200C is a transconductance amplifier whose current output is directly
proportional to the input voltages from a high accuracy AC or DC voltage standard.
The ratios of 10 volts to output is:
1:1, 1:0.1, 1:0.01,
1:0.001 and 1:0.0001
Recommended for DC – Models 511 and 521
Recommended for AC – Models 4601, 4503 or 4032
For watt hour systems
see System 4700. The 3200C may also be used with
AC and DC voltage sources (calibrators) of other manufacturers.

* Distortion: Added to the distortion
of the AC voltage calibrator.
Accuracy:
DC, ±(0.01% of setting + 0.01% of range + 10µA); AC, ±(0.05% of setting + 0.01%
of range + 20µA).
Line Regulation: ±0.0005% for ±10% line change.
Stability: DC, 0.001% of range; AC, 0.005% of range.
Isolation: Floating output; limited only by the isolation of
the driving voltage source.
