                                    The Model 3455A Digital Voltmeter makes ac volt-
age measurements with five digit resolution and dc voltage
and resistance measurements with 5 or 6 digit resolution as
programmed by the user. The 3455A employs an automatic
calibration (AUTO CAL) feature which automatically corrects
for possible gain and offset errors in the analog circuitry
to provide maximum accuracy. A removable reference module
permits external calibration of the dc voltage and
resistance functions. The reference module can be removed,
calibrated and returned to the instrument, or the module can
be replaced with another recently calibrated reference. A
MATH feature permits voltage or resistance measurements to
be scaled into convenient units or to b& read directly in
percent error from a selected reference. The 3455A is HP-IB
programmable for system applications.
