Safety Precautions

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 :

Power, Power Factor, Apparent Power, Reactive Power, Active Energy):

( 1 . ) Active Power(kW) and Power Factor (PF) (Figure 8 )

a.

a. Press

the Power Factor value, “ PF ” symbol are shown in the secondary display. W hen the

Power Factor value is negative, the loading is capacitive.

b. The maximum measurement range of Active Power is 600 k W . For exceeding the

maximum value, the “ OL ” symbol will be shown in the display. If test voltage

exceeds 600V or the test current exceeds 1000A , the “ OL ” symbol will be shown in

the display too. And the bar graph is full.(Figure 9 ) The minimum input voltage is

20V and the minimum input current is 5 A , if it less than the minimum input voltage

and minimum input current, the Active Power value is “ 0.00k W ” .

formula to calculate Reactive Power value. The value is calculated and shown

according to measured voltage, current and Active Power in software.

(3.) Active Energy (kWh) and Time （hmin ）

a. In Active Energy measurement mode, voltage signal must be input into V1 and COM

terminal of the clamp meter (Figure 11) , and the selector must be turned to Φ1 .S o

the Active Energy measurement function is valid ,

( Figure11. Active Energy measurements)

b. Press

button, starting value of the Active Energy is “ 0 . 000kW h ” and is

shown in the primary display at first, Active Energy measured time and the bar graph

“ 0-2 0- 4 0- 6 0 -8 0 -10 0 ” is shown in the secondary display. For the time is longer, the

measured value of Active Energy is larger. If you need read the Active Energy value

sometime, press the HOLD button, so the measured value display and the display of

the measured time are locked, but the Active Energy measurement is continuing

and timing in the clamp meter. After reading the display, press HOLD button again to

exit date hold and continue to measure, Active Energy value still add up. Active

energy measurement don ’ t stop until select other measurement function.

c. The

MAX

button and

MIN

button is invalid in Active Energy measurement

mode.

d. The maximum value of Active Energy is “ 9999 kWh ” . If Active Energy value exceeds

the maximum value , the display will show “ OL ” symbol.

e. Active energy measurement is viable in single-phase circuit because you only

measure current of one phase at one time, so you can not measure three-phase

Active Energy. If you need measure Active Energy for long during measurement, you

are suggested that you can use EX- P function, the meter will work no using the

battery but test voltage signal as power supply.

1. Refer to Table 3, connect yellow test lead, green test lead, red test lead to every phase live

wire of the three-phase circuit and V1 jack, V2 jack, V3 jack of the meter respectively, connect

black test lead to zero conductor of the circuit and COM jack of the meter.

2. Turn the selector to Φ1 at first ( to first phase measurement ) , hook the clamp jaw around the

first phase conductor of the tested circuit, press

kW / PF

button to measure Active Power (kW)

and Power Factor (PF). the measured value are shown in the LCD then

press button to sum power parameter of this phase; press

kVAr

kVA

button again to

measure Apparent Power and Reactive Power, after the result is shown in the LCD, press

button to sum power parameter of this phase. So power parameter measurement is

completed in the first phase. If you need save the result, you can press

then the display shows total Active Power value and Power Factor

value of the three-phase load (Figure 15). After display for three seconds, the display

switches to show total Apparent Power value and total Reactive Power value

automatically(Figure 16). The total Apparent Power value is in the primary display and the

total Reactive Power value is in the secondary display. The display switches automatically

every three seconds until you turn the meter to other function.

serial port of a computer. Then the meter can transmit measured data to computer by the

infrared photoelectricity RS232C interface in real-time mode. If you want to take out the

interface cable from the meter, first you must rotate the cable widdershins to unlock it, then you

can pull out it .

You will install the special data record software into the computer according to README.TEXT

When the LCD displays the “ ” symbol, the batteries must be

replaced to maintain proper operation. Use the following procedure

to replace the batteries:

1. Disconnect test leads from any signals, turn the rotary function switch to OFF, and remove

the test leads from the input terminals.

2．Open the battery cover and remove the battery cover. Because there is a locked design in

the battery cover. Don ’ t force the

battery cover open, otherwise the cover is broken. Refer to Figure 23 for opening it: Insert

a coin into the groove of the battery cover, press the coin down, then open the cover.

3．Remove batteries and replace with new batteries which is the same type or rating.
