WARRANTY

This instrument is warranted to be free from defects in material and

workmanship for a period of one year. Any instrument found defective

within one year from the delivery date and returned to the factory with

transportation charges prepaid, will be repaired,adjusted, or replaced at no

charge to the original purchaser. This warranty does not cover expandable

items such as battery. If the defect has been caused by a misuse or

abnormal operating condition, the repair will be billed at a nominal cost.

INTRODUCTION

This instrument is a 3 5/6digits true-RMS auto range digital clamp meter

current measurement, non-contact AC voltage detection, relative

measurement, MIN MAX mode, data hold, bar graph, backlight, low battery

indication, automatic power-off, illumination, full-range overload

protection, etc. It is easy to operate and is a useful test tool

SAFETY INFORMATION

This meter has been designed according to IEC 61010 concerning

electronic measuring instruments with a measurement category ( CAT III

1000V ) and Pollution Degree 2.

Warning

To avoid possible electric shock or personal injury, follow these

guidelines:

Do not use the meter if it is damaged. Before you use the meter,

inspect the case. Pay particular attention to the insulation surrounding

the connectors.

Inspect the test leads for damaged insulation or exposed metal. Check

the test leads for continuity. Replace damaged test leads before you

use the meter.

Do not use the meter if it operates abnormally.

Protection may be impaired. When in doubt, have the meter serviced.

Do not operate the meter where explosive gas, vapor or dust is

present.

Do not apply more than the rated voltage, as marked on the meter,

between terminals or between any terminal and earth ground.

Before use, verify the meter's operation by measuring a known

voltage.

When servicing the meter, use only specified replacement parts.

Use caution when working with voltage above 30V ac rms, 42V ac

peak, or 60V dc. Such voltages pose a shock hazard.

When using the probes, keep your fingers behind the finger guard on

the probes.

When making connections, connect the common test lead before you

connect the live test lead. When you disconnect test leads, disconnect

the live test lead first.

Remove the test leads from the meter and the clamp from any

conductor under test before you open the battery cover or the case.

Do not operate the meter with the battery cover or portions of the case

removed or loosened.

To avoid false readings, which could lead to possible electric shock or

personal injury, replace the batteries as soon as the low battery

- 5 -

indicator ( ) appears.

When in Relative mode or Data Hold mode or after zeroing the display

in DC current function, caution must be used because hazardous

voltage may be present.

Use the meter only as specified in this manual; otherwise the

protection provided by the meter may be impaired.

Adhere to local and national safety codes. Individual protective

equipment must be used to prevent shock and arc blast injury where

hazardous live conductors are exposed.

To avoid electric shock and personal injury, do not touch any naked

conductor with your hand or skin; and do not ground yourself while

using this meter.

Do not use the meter if the meter, a test lead or your hand is wet.

Remaining endangerment:

When an input terminal is connected to dangerous live potential, it is to

be noted that this potential can occur at all other terminals!

Do not use the VFD voltage measurement function or VFD current

measurement function to verify the presence of hazardous voltages or

currents. Voltages or currents greater than what is indicated may be

present.

CAT III - Measurement Category III is for measurements performed in

the building installation. Examples are measurements on distribution

boards, circuit breakers, wiring, including cables, bus-bars, junction

boxes,switches, socket-outlets in the fixed installation, and

equipment for industrial use and some other equipment, for example,

stationary motors with permanent connection to the fixed installation.

Do not use the meter for measurements within Measurement Category

IV.

Caution

To avoid possible damage to the meter or to the equipment under test,

follow these guidelines:

Disconnect circuit power and discharge all capacitors thoroughly

before testing resistance, continuity, diode,capacitor, or temperature of

an object.

Use the proper terminals, function and range for your measurements.

Before pressing a button to change function, disconnect the test leads

and the clamp from any object under test.

17. Bar Graph

The bar graph on the top of the LCD is like the needle on an analog meter.

It has an overload indicator ( ) on its right and a negative polarity

indicator ( ) on its left. The number of lit segments indicates the

measured value and is relative to the full-scale value of the selected range.

In the 600V range, for example, the major divisions on the scale represent

0, 100, 200, 300, 400, 500 and 600V. An input of -100V lights the negative

sign and the segments up to the " 10 " on the scale.

Note:

In frequency, duty cycle, temperature and capacitance measurement

functions and non-contact ac voltage detection function, the bar graph is

turned off.

For frequency measurements with the rotary switch in the"H%" position, the

amplitude of the input signal is required tobe in the range of 2V rms to 20V rms.

When the meter is measuring ac voltage and frequency at thesame time with

the rotary switch in the " " position, thefrequency measurement range is

10Hz to 1kHz and theinput voltage for frequency measurements is required

to be >2V(the higher the frequency of input signal, the higher therequired

input voltage ).

For frequency measurements with the rotary switch in the "VFD " position,

the measuring range is 10Hz to 1kHz,andthe input voltage is required to be

> 1/3 of the present voltagerange(the higher the frequency of input signal,

the higher therequired input voltage ).

When the meter is measuring VFD current and the freguency ofthe current

at the same time, the frequency measurement rangeis 10Hz to 1kHz, and the

amplitude of the current for frequency measurement is required to be > 1/3

of the present currentrange(the higher the frequency of input signal, the

higher therequired current to be tested ).
