SAFETY INFORMATION
To ensure that you use this device safely, follow the
safety guide lin es lis te d bel ow :
This meter is for indoor use, altitude up to 2,000 m.
The warnings and precautions should be read and well
understood before the instrument is used.
Use this device only as specified in this manual; otherwise,
the protection provided by the meter may be impaired.
When measuring in-circuit components, first de-energize
the circuits before connecting to the test leads.
Discharge capacitors before testing.
The power for the meter is supplied with a single standard
9V batter y. It is also possibl e t o use exter nal pow er usi n g
a 12V DC adaptor conforming to IEC 60950.

Introduction
This 19,999-count L/C/R hand-held 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 is also capable of series mode
measurement. The meter provides direct and accurate
measurements of inductors, capacitors and resistors with
different testi ng frequencies. It is possible to select betw een
auto and manual ranging.
Front panel pushbuttons maximize the convenience of
function and feature selection such a s data hold; maxim um,
minimum a nd average rec ord m od e; r el ati ve mo de; 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 and CP-09 software.
A tilt stand provides position flexibility for viewing and
operating the meter. The rubber over-molded case both
protects t he mete r in hars h envi ronments, and i mproves grip
in the han d. Whil e single 9V b attery opera tion is stand ard f or
the meter, a standard DC 12V power adaptor can also be
used as an optional power input.
