INTRODUCTION.

1-2. This Operating and Service Manual contains information necessary to install, operate, test, adjust, and service the Hewlett-Packard Model 3455A Digital Voltmeter.

1-3. Included with this manual is an Operating information supplement. The supplement is a duplication three sections instrument for use by the operator.

INSTRUMENT

1-8. Instrument identification by serial number is located on the rear panel. Hewlett-Packard uses a two-section serial number consisting suffix separated by a letter designating the country in which the instrument was manufactured. (A = U.S.A.; G

=West Germany; J =Japan; U =United Kingdom.) The

prefix is the same for all identical instruments and changes

only when a major instrument change is made. The suffix, however, is assigned sequentially and is unique to each instrument.

INFORMATION

age measurements with five digit resolution and de 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 cor-

rects for possible gain and offset errors in the analog circuitry to provide maximum accuracy. A removable reference module permits external calibration 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 be read directly in percent error from a selected reference. The 3455A is HP-IB programmable for system applications.
