1. Safety Specification
This instrument is designed according to EN61010-1 Specification. The main pur-
pose of this Specification is to ensure that the instrument will be used in the labor-
atory or the factory safely; it is not suitable for outdoor applications, especially the
moistened or dusty locations. Abnormal use of this instrument may cause the elec-
trocution hazard. Before using this instrument, please read the descriptions of this
Specification carefully toavoid causing accidentdue to incorrect or unintended use.
1.1 Safety marks (the following safety marks may appear in this Manual)
Caution :
Please read the content of this Manual carefully.
High-voltage
hazard symbol：
The output terminal may release lethal voltage. Please
read the safety instructions described in this chapter.
Grounding：
Before working with this tester, be sure to connect this
terminal with the ground to prevent from touching the
housing as to cause electrocution accident due to cur-
rent leakage.
Warning sign：
If the product is improperly used, it may cause adverse
result to the instrument or the Test Piece. If the product
is improperly used, it may cause injury or even death.
1.2 Electrocution
To prevent electrocution accident from occurring, it is suggested that the operator
wear insulating rubber globes before working with the machine and then start the
test-related activities.
1.3 Grounding
The back panel of the instrument is fitted with a safe ground terminal. Be sure to
connect this ground terminal to the ground to prevent the operator from touching
the housing as to cause the electrocution.
1.4 Power Source
The scope of power used by this instrument is 88~264Vac. To insert the power
source, please check if the power to be connected is identical with the power-
shifting sign indicated on the back panel. When changing the fuse, it is required
to use specific type of fuse designed in same ampere to prevent the electrical wire
from burning. Before making any replacement, please remove the plug to prevent
danger.
1.5 Warm-up

3
The instrument will operate normally upon starting the power. To achieve the
specified accuracy, it is suggested warming up the instrument for over 15 minutes
1.6 External control unit
This unit is able to execute the external control. For this purpose, please ensure
that the operator is not touching the signal output end and the Test Piece to avoid
causing hazard.
1.7 Machine failure
Stop using the instrument immediately when finding it is operating abnormally,
such as significant difference is existed between the current displayed on the cur-
rent meter andthedesign value; or the current isnot supplied, but theoverlapping
current indicator remains illuminated continuously. In this case, please contact us
or your dealer to provide technical support.
1.8 Ending the test
When not using the instrument, please shut off the Power Switch. To restart the
Power Switch after being disconnected, please wait for fewseconds; however, do
not execute consecutive on/off action of the power.
1.9 Installation, storage
Normal operating temperature and humidity scope of the instrument is 5oC~40oC
and 80% RH respectively, and the instrument may act abnormally if exceeding
such range. The storage temperature and humidity scope of the instrument is -
20oC~ 70oC and 80% RH respectively. To achieve correct testing and to protect
safety, do not install the instrument inthe environment exposing to direct sunshine
or high temperature, high humidity, frequency oscillation and rich dust.
1.10 Emergency treatment
Upon the occurrence of electrocution, burning of the Test Piece or the burning of
Main Unit, please disconnect the Power Switch and remove the power cord plug
immediately to avoid causing a hazard.
1.11 General instructions
⚫Do not place any combustible or heavy object on the instrument.
⚫Avoid heavy impact that may damage the machine.
⚫When cleaning the instrument, remove the power plug first and then
wipe with the soft cloth soaked with mild cleanser and fresh water.
⚫If the instrument presents any Tolerance sign, do not attempt to dis-
mantle it for making repairs; instead, send the instrument to our pro-
fessional maintenance personnel for solving the problem.

2. Preface
In this chapter, we briefly introduce the characters, key features and specifications
of 6630 LCR Meter.
2.1 Introduction
The test frequency of the 6630 LCR Meter is DC 10Hz-30MHz and the test signal
is 10mV-2Vrms(min. resolution 1mV), and is suitable for the LCRand DCR testes
of AC signals. The measurement in a continuously changing environment can be
executed stage-by-stage with the test frequency and grade, and high-speed con-
tinuous tests can be performed under different test and mode conditions. The
machine also supports LAN, USB and GPIB PC connection capabilities to im-
prove the design and test efficiency significantly. MICROTEST 6630 Impedance
Analyzer also provides fixtures for material dielectric permittivity measurement
that allows PCB designed engineers to reduce the faulty conditions with the com-
prehensive information of permittivity while designing PCB layouts.
The performance, convenience and operation flexibility of the LCR Meter have
become indispensable tools for the professional measuring technicians. In addi-
tion to providing full-range solutions for the testing equipment over the past years,
Microtest also developed the new model of “6630 LCR Meter” that has contributed
to more perfect precision solutions for the test. Such analyzer can meet customer
demands for price, speed, capacity, accuracy and multi-function by its well-based
flexibility in combination and implementation. Therefore, it can be used in the test-
ing of a variety of components such as resister, capacitor, inductor, oscillator,
sensor, time-delay wire, filter and resonator.

3.4.4 Fixture Connecting
When connecting the fixture, it is required to discharge the power of Test
Piece thoroughly. Turn the latches on both sides of the fixture to left until
aligning with the small protruding point on the BNC port. Push the fixture
down to the end and then rotate the latch rightward for fixing the fixture.
Next, execute O/C and S/C trimming (See7. Correction) and load the
measured Test Piece in-between both locking plates on the fixture. Then
fasten the screws to secure the Test Piece and the measuring process
can be started.
