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 220V 198~242V 50/60Hz 240V 216~264V 50/60Hz

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

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.
