Automatic Balancing Current Comparator Technology 3-4 Terminal Measurements Lead Compensation Circuit Overall Accuracy 20 ppm Range Extension Option with 7020H





MODEL INFORMATION


The Model 7010B offers a wider capacitance range and
increased voltage sensitivity. Minimum voltage
sensitivity for full scale accuracy is 100 volts. The
7010B is a microprocessor controlled, metrology based,
high voltage capacitance bridge. Its operation is fully
automatic. A large vacuum florescent display presents
relevant measuring quantities such as capacitance (Cx)
and dissipation factor (Tan ). Easy to use front panel
keyboard menus allow the operator to select the
number of readings for statistical analysis of uncertainty
calculations at the 95% (2s) level. All measured
parameters can be transmitted over the IEEE488
interface for storage to a computer.

The model 7010B is a capacitance bridge with a ratio of
1000:1 making it ideal for both low and high voltage
applications. The automatic self-balancing feature
facilitates the use of the bridge for accurate load loss
measurements of large high voltage inductive loads.
The 7010B may also be used for calibration of precision
standard capacitors, tan-delta measurements and of
precision potential transformers. Overall accuracy is
<20 ppm in magnitude and phase. The technology is
based on the two-stage-current-comparator-principle.
The 7010B has a capacitance ratio up to 1000:1 and
dissipation (loss tangent) of 0 to 10% with a resolution
of 1 ppm. To accommodate capacitance ratios larger
than 1000:1 an additional two stage range extender,
model 7020H, may be added to increase the ratio to
1,000,000:1. All connections are made on the rear of
the instrument. The model 7010B is fully protected
against transients.

The effect of lead and winding impedance on the
measurement accuracy has been reduced by means of
a built-in lead compensation circuit.
