SAFETY
SUMMARY
The
following
general
safety
precautions
must
be
observed
during
all
phases
of
op-
eration,
service,
and
repair
of
this
instrument.
Failure
to
comply
with
these
pre-
cautions
or
with
specific
warnings
given
elsewhere
in
this
manual
violates
safety
standards
of
design,
manufacture,
and
intended
use
of
the
instrument.
Hewlett-
Packard
Company
assumes
no
liability
for
the
customer's
failure
to
comply
with
these
requirements.
GROUND THE INSTRUMENT
To
minimize
shock
hazard,
the
instrument
chassis
and
cabinet
must
be
connected
to
an
electrical
ground.
The
instrument
is
equipped
with
a
three-conductor
ac
power
cable.
The
power
cable
must
either
be
plugged
into
an
approved
three-contact
electrical
outlet
or
used
with
a
three-contact
to
two-eontaet
adapter
with
the
grounding
wire
(green)
firmly
connected
to
an
electrical
ground
(safety
ground)
at
the
power
outlet.
The
power
jack
and
the
mating
plug
of
the
power
cable
meet
International
Electrotechnical
Commission
(IEC)
safety
standards.
Do
not
operate
the
instrument
in
the
presence
of
flammable
gases
or
fumes.
Op-
eration
of
any
electrical
instrument
in
such
an
environment
constitutes
a
definite.
safety
hazard.
KEEP
AWAY
FROM
LIVE
CIRCUITS
Operating
personnel
must
not
remove
instrument
covers.
Component
replacement
and
internal
adjustments
must
be
made
by
qualified
maintenance
personnel.
Do
not
replace
components
with
power
cable
connected.
Under
certain
conditions,
dan-
gerous
voltages
may
exist
even
with
the
power
cable
removed.
To
avoid
injuries,
always
disconnect
power
and
discharge
circuits
before
touching
them.
DO
NOT
SERVICE
OR
ADJUST
ALONE
Do
not
attempt
internal
service
or
adjustment
unless
another
person,
capable
of
rendering
first
aid
and
resuscitation,
is
present.
DO
NOT
SUBSTITUTE
PARTS
OR
MODIFY
INSTRUMENT
Because
of
the
danger
of
introducing
additional
hazards,
do
not
install
substitute
parts
or
perform
any
unauthorized
modification
to
the
instrument.
Return
the
in-
strument
to
a
Hewlett-Packard
Sales
and
Service
Office
for
service
and
repair
to
ensure
that
safety
features
are
maintained.
DANGEROUS
PROCEDURE
WARNINGS
Warnings,
such
as
the
example
below,
precede
potentially
dangerous
procedures
throughout
this
manual.
Instructions
contained
in
the
warnings
must
be
followed.
WARNING
Dangerous
voltages,
capable
of
causing
death,
are
present
in
this
instru-
ment.
Use
extreme
caution
when
handling,
testing,
and
adjusting.

SECTION I
GENERAL INFORMATION
1-1. INTRODUCTION.
1-2. This operating and service manual contains
the information required to install, operate, test,
adjust and service the Hewlett-Packard Model
4262A Digital LCR Meter. Figure 1-1 shows the in-
strument and supplied accessories. This section
covers specifications, instrument identification,
description, options, accessories, and other basic
information.
1-3. Listed on the title page of this manual is a
~ tnicrofiche part number. This number can be used
to order 4 x 6 inch microfilm transparencies of the
manual. Each microfiche contains up to 60 photo-
duplicates of the manual pages. The microfiche
package also includes the latest manual changes
supplement as well as all pertinent service notes.
To order an additional manual, use the part num-
ber listed on the title page of this manual.
1-4. DESCRIPTION.
1-5. The HP Model 4262A LCR Meter is a general
«
FAS
445
P/N 8120-1378
purpose, fully automatic test instrument designed
to measure the parameters of an impedance ele-
ment with high accuracy and speed. The 4262A
measures capacitance, inductance, resistance (equi-
valent series resistance) and dissipation factor or
quality factor over a wide range at test frequencies
of 120Hz, 1kHz and 10kHz employing a five-term-
inal connection configuration between the com-
ponent and the instrument. The measuring circuit
for the device to be measured is capable of both
parallel and series equivalent circuit measurements
and the measured values are displayed by the two
three-full digits LED displays on the front panel.
A convenient diagnostic function, also featured in
the 4262A, is actuated by a SELF TEST switch.
This confirms functional operation of the instrument.
1-6. The measuring range for capacitance is from
0.01pF to 19.99mF, inductance from 0.014H to
1999H, and resistance from ImQ to 19.99M2,
which are measured with a basic accuracy of 0.2
to 0.3% depending on test signal level, frequency,
and measuring equivalent circuit, and at typical
measuring speeds of 220 to 260 milliseconds at

ment can be negated by
switch on internal board).

mum display is 199).

Measurement Terminals: 5-terminal configura-
tion (high and low terminals for both
potential and current leads plus guard), ==
Range Modes: LCR - Auto and Manual

and 10kHz +3%.
Test Signal Level: Normal level: 1Vrms.
- Low level : 50mVrms (parallel

Warm-up Time: 15 minutes
Deviation Measurement: When 2LCR key is de-
pressed, the existing measured value
is stored as a reference value and
displayed value is offset to zero. The
range is held and deviation is dis-
played as the difference between the
referenced value and subsequent re-
sult. (Deviation spread in counts
from -999 to 1999).
Offset Adjustment: Stray capacitance and re-
sidual inductance of test jig can be
compensated for as follows:
C: up to 10pF

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 de bias voltages, LC zero
adjustment, and options providing BCD output,
HP-IB interfacing capability, or a comparator func-
tion.

2-3. INITIAL INSPECTION.
2-4,
The
4262A
LCR
Meter,
as
shipped
from
the
_
factory,
meets
all
the
specifications
listed
in
Table

On
receipt,
inspect
the
shipping
container
for
damage.
If
the
shipping
container
or
cushioning
material
is
damaged,
notify
the
carrier
as
well
as
the
Hewlett-Packard
office
and
be
sure
to
keep
the
shipping
materials
for
carrier’s
inspection
until
the
contents
of
the
shipment
have
been
checked
for
completeness
and
the
instrument
has
been
checked
mechanically
and
electrically.
The
contents
of
the
shipment
should
be
as
shown
in
Figure

The
procedures
for
checking
the
general
electrical
op-
eration
are
given
in
Section

Ba-
sic

and
the
procedures
for
checking
the
4262A
LCR
Meter
against
its
specifi-
cations
are
given
in
Section
IV.
Firstly,
do
the
self
test.
If
the
4262A
LCR
Meter
is
electrically
ques-
tionable,
then
do
the
Performance
Tests
to
deter-
mine
whether
the
4262A
has
failed
or
not.
If
con-
tents
are
incomplete,
if
there
is
mechanical
damage
or
defects
(scratches,
dents,
broken
switches,
etc.),
or
if
the
performance
does
not
meet
the
self
test
or
performance
tests,
notify
the
nearest
Hewlett-
Packard
office
(see
list
at
back
of

The
HP

will
arrange
for
repair
or
replacement
without
waiting
for
claim

SELECTION OF OPERATING VOLTAGE
Operating voltage is shown in module window
and is usually set to 120V at factory. `
_ 1. Disconnect power cable and slide module
window to left.
2. Pull FUSE PULL lever and rotate to left.
This removes line fuse.
3. Select operation voltage by orienting PC
board to position desired voltage on top-
left side. Push board firmly into module
slot.
4. Rotate FUSE PULL lever back to its normal
position and re-insert fuse in holder be
careful to select correct fuse value.
