ACCESSORIES
6-1. PRECISION VOLTAGE DIVIDERS
The Fluke
BOA,
BOB, and
BOC
Precision Voltage Dividers
provide the
W
BOO Series Differential Voltmeters with the
ability to mike 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
maxi-
mum 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
terqierature coefficient.
To
further ensure high accuracy
and long term stability at very high voltages, the BOC
dividers have all resistance components immersed in oil
within a hermetically sealed container. As an addition-
al feature, all BOB and BOC models are provided with a
1
volt tap which allows measurements of high voltages with
a laboratory potentiometer. Specifications for the stan-
dard models are shown on next page. Other intermediate
models are available upon special request.
