Information
The Model 515 Megohm Bridge is a Wheatstone Bridge for
measuring resistors from 10⁵ ohms to 10⁻¹⁵ ohms with
accuracies from 0.05% to 1.0%. It is complete, with an
electrometer null detector, shielded enclosure for the
unknown, and a bridge voltage supply.
A unique system of switches is provided to allow corrections
to be made for the slow changes in resistance of the
standard high megohm resistors. This enables all values of
resistance to be read with rated accuracy, directly from the
bridge dials.
Bridge voltages in one volt steps up to 10 volts are
available from the internal supply. With external supplies,
voltages as high as 1,000 volts can be used.
A connector is provided so that unknown resistors can be
measured outside the instrument as well as in the built-in
shielded enclosure.
