HP 4262A User Manual

Model 4262A
1kHz and 10kHz and about 900 milliseconds at
120Hz. The wide range capability of the 4262A
enables a measurement range from small capaci-
tances such as mica capacitors and the para-
sitic capacitance of a semiconductor device
through high capacitances such as the measurement
of electrolytic capacitors to be covered. A wide
range of inductance measurements from the in-
ductance of a high frequency transformer to that
of a power transformer can be measured. The wide
resistance range permits the measurement of wire-
wound resistors through the measurement of solid
resistors. In parallel capacitance measurements,
either a test signal level of 1Vrms, or 50mVrms
can be selected.
1-7. The 4262A has the capability of making
capacitance, inductance, and resistance deviation
measurements. This function is enabled by pushing
the A LCR switch to display the deviation of a re-
ference value. When the A LCR switch is depressed
the reference value is obtained and memorized
from the preceding measurement. The practi-
cal use of this feature is evident when it is desired
to make a measurement on a variable capacitor:
First, the minimum value is measured, then the A
LCR button is pushed, Minimum to maximum capa-
citance is now displayed as the capacitor is rotated
through its range. For parallel capacitance meas-
urements, test signal levels of either 1Vrms or
50mVrms may be selected. Other versatile 4262A
capabilities and features are, for example, the use
of internal and external dc bias voltages, LC zero
adjustment, and options providing BCD output,
HP-IB interfacing capability, or a comparator func-
tion.
1-8. SPECIFICATIONS.
1-9. Complete specifications of the Model 4262A
LCR Meter are given in Table 1-1. These specifi-
cations are the performance standards or limits
against which the instrument is tested. The test
procedures for the specifications are covered in
Section IV Performance Tests. Table 1-2 lists gen-

eral information. General information is not speci-
fications but is typical characteristics included as
additional information for the operator. When the
4262A LCR Meter is shipped from the factory, it
meets the specifications listed in Table 1-1.
1-10. SAFETY CONSIDERATIONS.
1-11. The Model 4262A LCR Meter has been
designed to conform to the safety requirements of
an IEC (International Electromechanical Com-
mittee) Safety Class I instrument and is shipped
from the factory in a safe condition.
1-12. This operating and service manual contains
information, cautions, and warnings which must be
followed by the user to ensure safe operation and
to maintain the instrument in a safe condition.
1-13. INSTRUMENTS COVERED BY
MANUAL.
1-14. Hewlett-Packard uses a two-section nine
character serial number which is marked on the se-
rial number plate (Figure 1-2) attached to the in-
strument rear panel. The first four digits and the
letter are the serial prefix and the last five digits are
the suffix. The letter placed between the two sec-
tions identifies country where instrument was
manufactured. The prefix is the same for all iden-
tical
instruments;
it
changes
only
when
a
change
is
made to the instrument. The suffix, however, is as-
signed sequentially and is different for each in-
strument. The contents of this manual apply to in-
struments with the serial number prefix(es) listed
under SERIAL NUMBERS on the title page.
1-15. An instrument manufactured after the
printing of this manual may have a serial number
prefix that is not listed on the title page. This un-
listed serial number prefix indicates the instrument
is different from those described in this manual.
The manual for this new instrument may be ac-
companied by a yellow Manual Changes supple-
ment or have a different manual part number.
This supplement contains ‘“change information”
that explains how to adapt the manual to the
newer instrument.
1-16. In addition to change information, the
supplement may contain information for correct-
ing errors (called Errata) in the manual. To keep
this manual as current and accurate as possible,
Hewlett-Packard recommends that you periodically
request the latest Manual Changes supplement. The
supplement for this manual is identified with this
manual’s print date and part number, both of
which appear on the manual’s title page. Com-
plimentary copies of the supplement are available
from
Hewlett-Packard.
