SAFETY INFORMATION

In this manual, "WARNING", is reserved for condi ti o ns and actions that
pose hazard(s) to the user; "CAUTION", is reserved for conditions and
actions that may damage your meter. Before using the meter, read the
following safety information carefully.

1. Before applying power, ensure that power cord and the proper line
voltage indicated for power source being used.

2. This product is grounding through the grounding conductor of the
power cord. To avoid electric shock, the grounding conductor must
be connected to earth gr ound. Be fore making any connectio ns to th e
input terminals of the products, ensure that the properly grounded.

3. To avoid personal injury, never operate the instrument without
covers or panels removed.

4. Do not operate this product in wet, damp or explosive atmosphere.

5. This meter is for indoor use, altitude up to 2,000 m.

6. The warnings and precautions should be read and well understood
before the instrument is used.

7. Use this device only as specified in this manual; otherwise, the
protection provided by the meter may be impaired.

8. When measuring in-circuit components, first de-energi ze the circuits
before connecting to the test leads.

9. Discharge the capacitor before testing.

10. The meter is safety-certified in compliance with EN61010 (IEC
1010-1). EMC is certified in compliance with EN61326-1.

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
