INTRODUCTION
The meter is a bench type instrument for testing inductance,
capacitance and resistance. If this device is damaged or something is
missing, contact the place of purchase immediately.
This 19,999-count L/C/R meter is a special microprocessor-controlled
meter for measuring functions of inductance, capacitance and
resistance. Extremely simple to operate, the instrument not only takes
absolute parallel mode measurements, but also capable of series mode
measurement. The meter provides direct and accurate measurements
of inductors, capacitors and resistors with different testing frequencies.
It is selectable for auto and manual ranging.
Front panel pushbuttons maximize the convenience of function and
feature selection such as data hold; maximum, minimum and average
record mode; relative mode; tolerance sorting mode; frequency and
L/C/R selection.
The test data can be transferred to PC through an optional full isolated
optical RS232C interface.
A tilt stand provides position flexibility for viewing and operating the
meter. Its portability and stackable design makes this valuable
instrument for electronic engineer, communications technician, schools
and laboratories using.

CAUTIONS
In order to avoid damaging this instrument, make sure that the unit is
set to the correct line voltage for your area. Also make sure that the
correct fuse is used for the line voltage. These line voltages are 100V,
120V, 220V and 240V at 50/60HZ.
WARNING
To avoid damage the equipment use only specified fuse when change
the power line voltage. Please refer to following table
SELECTOR LINE VOLTAGE FUSE 5x20mm
100V 90~110V 50/60Hz
120V 108~132V 50/60Hz
T 125mA
220V 198~242V 50/60Hz
240V 216~264V 50/60Hz
T 63mA
Although this instrument is protected against reverse polarity damage
the circuit being powered may not include such protection. Always
carefully observe polarity incorrect polarity may damage the equipment
under test. Do not exceed the voltage rating of the circuit being powered.

MAINTENANCE
WARNING
To avoid electrical shock, do not perform any service
unless you are qualified to do so.
 Service
If the instrument fails to operate, to check line-power, power cord, fuses
and test leads, and replaces them if necessary. If the instrument still
can’t work, double check operating procedure as described in this
instruction manual. When servicing, use specified replacement parts
only. The meter must be completely turned off while replacing the fuse.
WARNING
To avoid electrical shock or damaging the meter, never
get water inside the case.
 Cleaning the Meter
Before cleaning this meter, make sure the power is
switched to OFF position and the power cord has been
removed. To clean the meter, wipe the dirty parts with
gauze or soft cloth soaked with diluted neutral detergent.
Do not get too wet to prevent the detergent from
penetrating into inside parts and causing damages. After
cleaning, make sure the instrument is dried completely
before using.
