Safety Information
This Meter complies with the standards IEC61010: in pollution degree 2, overvoltage category (CAT. III 600V,CAT IV 300V) and double insulation. CAT. III: Distribution level, fixed installation, with smaller transient overvoltages than CAT. IV CAT.IV: Primary supply level, overhead lines, cable systems etc. Use the Meter only as specified in this operating manual, otherwise the protection provided by the Meter may be impaired. In this manual, a Warning identifies conditions and actions that pose hazards to the user, or may damage the Meter or the equipment under test. A Note identifies the information that user should pay attention to International electrical symbols used on the Meter and in this Operating Manual are explained on page 6.
Rules For Safe Operation
Do not apply more that the rated voltage, as marked on the Meter. When measurement has been completed, disconnect the
connection between the test leads and the circuit under test, remove the testing leads away from the input terminals of the Meter and turn
3
the Meter power off. Do not carry out the measurement when the Meter’s back case and / or battery door is opened to avoid electric shock. When the Meter working at an effective voltage over 30V in AC, special care should be taken.
Use the proper terminals and function for your Measurements. Do not use or store the Meter in an environment of high
temperature, humidity, explosive, inflammable and strong magnetic field. The performance of the Meter may deteriorate after dampened. Do not use the Meter if the surface of it is wet or the user’s hands are wet. When using the test leads, keep your fingers behind the finger guards. Replace the battery as soon as the battery Indicator appears. With a low battery, the Meter might produce false readings that can lead to electric shock and personal injury.  When opening the battery door, must make sure the Meter is power off. When servicing the Meter, use only the same model number or identical electrical specifications replacement parts. The internal circuit of the Meter shall not be altered at will to avoid damage of the Meter and any accident. Soft cloth and mild detergent should be used to clean the surface of the Meter when servicing. No abrasive and solvent should be used to prevent the surface of the Meter from corrosion, damage and accident.
The Meter is suitable for indoor use. Turn the Meter off when it is not in use and take out the battery when not using for a long time. Constantly check the battery as it may leak when it has been using
for some time, replace the battery as soon as leaking appears. A leaking battery will damage the Meter.

A. AC Voltage (main display) + Frequency (secondary display) Measurement (see figure 4)
figure 4
The AC Voltage ranges are:15V, 100V, 300V and 600V The frequency range is:20Hz~100Hz To measure AC voltage + frequency, connect the Meter as follows:
11
1. Insert the red test lead into the V A terminal, blue test lead into the V B terminal, yellow test lead to V C input terminal and black test lead to the COM input terminal.
2. Connect the red test leads (VA input terminal), blue test leads (VB input terminal) and yellow test leads (VC input terminal) to the corresponding three phases loaded live wire. Black test lead (COM input terminal) to the corresponding three phases loaded neutral wire.
3. Press SELECT to select phase location, the display shows the corresponding phase symbol. VA means the first phase A, VB means the first phase B,VC means the first phase C.
4. The display shows the corresponding True RMS voltage value and frequency value of each phase.
5. Press MAX/▲ , the LCD displays MAX, it starts recording the maximum AC voltage True RMS value. Press MAX/▲ again to show the current AC voltage True RMS value.
6. Press MIN/▼ the LCD displays MAX, it starts recording the minimum AC voltage True RMS value. Press MAX/▼ again to show the current AC voltage True RMS value.
7. The display shows 9999 when the input voltage is higher than 600V rms.
Note
●When the measurement has been completed, disconnect the connection between the testing leads and the circuit under test and remove testing leads from the input terminals.
B. AC Current (main display) + AC Voltage (secondary display) Measurement
The AC current ranges are: 40A, 100A, 400A and 1000A The AC Voltage ranges are: 15V, 100V, 300V and 600V To measure AC current + AC voltage, connect the Meter as follows:
1. Press the Kw to select AC Current (main display) + AC Voltage (secondary display) range.
2. Press the lever to open the transformer jaw.
3. Center the conductor within the transformer jaw, then release the Meter slowly until the transformer jaw is completely closed, Make sure the conductor to be tested is placed at the center of the transformer jaw,
12
otherwise it will cause deviation. The Meter can only measure one conductor at a time, to measure more than one conductor at a time will cause deviation.
4. The double display shows the AC current True RMS value and AC voltage True RMS value.
5. Press MAX/▲, the LCD displays MAX, it starts recording the maximum AC current True RMS value. Press MAX/▲ again to show the present AC True RMS value.
6. Press MIN/▼ , the LCD displays MAX, it starts recording the minimum AC current True RMS value. Press MAX/▲ , again to show the present AC current True RMS value.
7. The display shows 9999 when the current of the tested conductor is higher than 1000A rms.
Note
●When the measurement has been completed, disconnect the connection between the conductor under test and the jaw, and remove the conductor away from the transformer jaw of the Meter.
C. Active Power (main display) + Phase Angle (secondary display) Measurement
The active power ranges are:40A, 100A, 400A and 1000A The phase angle ranges are: 0° ~360°
Warning
To avoid damages to the Meter or harms to you, do you measure higher than AC voltage 600 v.r.s. and AC current 1000A v.r.s.
To measure active power + phase angle, connect the Meter as follows:
1. Press the MENU to select Active power (main display) + Phase angle (secondary display) range.
2. Press the lever to open the transformer jaw, and clamp them to the corresponding phase of tested conductor. If user needs to measure any phase of the 3 phase, then clamp them to that phase’s conductor.
3. Connecting method (see figure 6, 7, 8):
● When measuring 3 phase 4 wires, connect the Meter as figure 6.
