Safety 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

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

power measurement, it is incorporated 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.

Feature

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

circuit, single-phase circuit.

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.

- 2 -

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

measure expending energy per hour of general 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 and store 28 groups of

measurement parameter.

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

three-phase measurement mode respectively.

7. Multifunctional button control, there are double scales analogue bar

graph to display fluctuation of voltage and current.

8. With PC RS232C interface and special WINDOWS data graphics

software.

9. Display 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 .
