Precautions

·Read these operation instructions thoroughly and completely before operating your meter. Pay

particular attention to WARNING. The instructions in these warnings must be followed.

·You must be careful when working with voltages above 30V AC. Keep fingers behind the probe

barriers while measuring.

·Never use the meter to measure voltages that might exceed the maximum allowable input value of

any function measurement mode.

·Always inspect your meter and test leads before every use. If any abnormal conditions exist: broken

test leads, cracked cases, LCD not reading, etc, do not attempt to take any measurement.

·Using the meter with the equipped test leads is only conform to safety requirements. If you need

instead broken test leads, you must replaced with the same as type and electric specification.

·Never touch a voltage source when the test leads are plugged into a current jack.

·Do not expose the instrument to direct sunlight, extreme temperature

or moisture.

General Description

Description

Three-phase digital power clamp meter is a handheld aptitude meter with power measurement, it is

incorporate d current meter and power measurement instrument. The meter is composed of three

channels: voltage, current, power and single chip Microcontroller. It has powerful measuring and

data processing software, and complete to measure, calculate and display of the 8 parameters :

Voltage, Current, Active Power, Power Factor, Apparent Power, Reactive Power, Active Energy,

Frequency. It has Stable capability, easy operation. It is especially suitable for measurement and

overhaul of the electric power equipment and the power-supply circuit on the spot. The structure of

the instrument is pincers , it is very small, very light and portable, make measurement easy and fast.

To

the power measurement user, the digital power clamp meter which is used completely in

three-phase system is one of the best instrument.

1. For power measurement of 3 - phase 3-wire circuit, 3 -phase 4- wire circuit , single - phase circuit.

2.

2. The instrument can complete the true RMS value measurement. If there is nonsinusoidal AC

current input signal, it can accurately measure the active current.

3. Using autorange switch circuit and modulus transducer which has 8000

count and high resolution, the instrument has high accuracy and easy operation.

4. Minimum current of Active Energy measurement is 0.5A , it can

m easure expending energy per hour of gener a l electrical equipment .

Measurement and display five parameters of power: Active Power, Apparent Power, Power Factor,

Reactive Power, Active Energy.

5. Double display two parameters on each menu a n d store 28 groups of

measurement parameter .

6. M easure five power parameters of each phase and total power value in

three -phase measurement mode respectively .

7. M ultifunctional button control , there are double scales analogue bar

graph to display fluctuation of voltage and current.

8. W ith PC RS 232 C interface and special WINDOWS data graphics

software.

9. D isplay measurement time and select tested voltage signal be power

supply for the clamp at one time in Active Energy measurement mode,

so the instrument can measure for long .

10. The instrument is a portable clamp meter. It is very light and

convenient to carrying .
