SPECiFICATIONS

Table i-I lists the specifications for the HP 85027 directional bridges. The specifications

are performance standards or limits against which the bridges may be tested. Table 1-2

lists supplemental characteristics, non-warranted but typical performance parameters,

useful in test applications.

SAFETY CONSIDERATIONS

The voltages in these directional bridges do not warrant more than normal caution for

operator safety.

The CAUTION sign in this manual identifies an operating

procedure or practice which, if not correctly performed, could

damage or destroy the equipment. Do not proceed beyond a

CAUTION sign until you fully understand and meet the

conditions indicated.

INSTRUMENTS COVERED BY MANUAL

You will find a two-part serial number on the bridge. The first four digits and the letter

are the serial number prefix. The last five digits are the sequential suffix which is

unique to each bridge. The contents of this manual apply directly to bridges with the

same serial number prefix as the one on the title page under the heading SERIAL

NUMBERS.

If the serial prefix of your bridge is not listed on the title page, your instrument is

different from those documented in this manual. The differences are documented in the

yellow manual changes supplement supplied with the manual.
