                                    1-1. INTRODUCTION
1-2. The Model 73IB DC Reference Standard is an ultra-
stable dc power supply which, when standardized, is capable
of providing a variety of precision output voltages with
standard cell accuracy. The 73 IB will furnish basic dc
voltage outputs of 10V, IV, ΔΕ (000 to 999 ßV),
1.018 +ΔΕ, and 1.019+ΔΕ.
1-3. The desired voltage mode is selected using a front
panel function switch and the value of ΔΕ is adjustable
using a 10-turn linear potentiometer. The front panel ΔΕ
control includes a 3 digit turn counter to indicate the
selected value of ΔΕ, i.e., 000 to 999 μν. The counter is
equipped with a locking lever to prevent accidental changing
of a selected ΔΕ setting.
1-4. A front panel guard connection is provided for use in
reducing errors causedby common mode voltages. The guarded
internal circuitry is isolated from the chassis and earth
ground.
1-5. Power to operate the 73IB can be derived from either an
internal battery pack for field or portable use, or from the
ac power line for bench use. A front panel meter indicates
the relative charge level of the internal battery pack
during portable use. The AC line requirements are 115/230V
ac, 50 to 400 Hz.
1*6. The 73IB is supplied with non-marring feet for bench or
field use. It may also be conveniently mounted in a standard
19” equipment rack using one of the rack mounting accessory
kits.
