ACCESSORIES
6-1. PRECISION VOLTAGE DIVIDERS
The Fluke 80A, 80B, and 80C Precision Voltage Dividers
provide the
800 Series Differential Voltmeters with the
ability to make high accuracy measurements up to 30,000 volts
DC. All models contain a zero center panel meter which allows
the polarity and approximate magnitude of the unknown high
voltage to be easily observed. At maximum input, all units
draw but 1 ma of current from the unknown. The extreme
accuracy and excellent long term stability of these dividers are
obtained by using properly aged precision wirewound resistors
which have a very low temperature coefficient. To further
ensure high accuracy and long term stability at very high
voltages, the 80C dividers have all resistance components
immersed in oil within a hermetically sealed container. As an
additional feature, all 80B and 80C models are provided with a
1 volt tap which allows measurements of high voltages with a
laboratory potentiometer. Specifications for the standard
models are shown on next page. Other intermediate models
are available upon special request.
